Here’s why and how Australia is changing gears.   𝗪𝗵𝘆 𝘁𝗵𝗲 𝘀𝗵𝗶𝗳𝘁  - 𝗗𝗲𝗺𝗮𝗻𝗱 𝗿𝗲𝗱𝗲𝗳𝗶𝗻𝗲𝗱 – High-renewables grids now lack “system-forming strength + flexibility”, not more spinning steel.  - 𝗠𝘂𝗹𝘁𝗶-𝗿𝗼𝗹𝗲 𝗮𝘀𝘀𝗲𝘁𝘀 – GFM BESS delivers strength while earning from arbitrage, frequency regulation and congestion relief, cutting total cost.  - 𝗟𝗼𝗰𝗮𝗹𝗶𝘀𝗲𝗱 𝗿𝗲𝗶𝗻𝗳𝗼𝗿𝗰𝗲𝗺𝗲𝗻𝘁 – Placed at Renewable Energy Zone (REZ) and bottlenecks to lift connection capacity directly.  - 𝗦𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝗲𝘃𝗼𝗹𝘂𝘁𝗶𝗼𝗻 – Firmware updates enable droop control, black-start and fault-ride-through to match new standards.   𝗞𝗲𝘆 𝗰𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲����  - 𝗙𝗮𝘂𝗹𝘁 𝗹𝗲𝘃𝗲𝗹𝘀 – GFM current limits demand adaptive protection coordination.  - 𝗖𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝗰𝗲 – Model alignment, parameter tuning and hold-point testing across scenarios.  - 𝗠𝗲𝗮𝘀𝘂𝗿𝗲𝗺𝗲𝗻𝘁 & 𝗽𝗮𝘆𝗺𝗲𝗻𝘁 – Defining verifiable “system-strength capability” and enforceable performance terms.  - 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗰𝗼𝗼𝗿𝗱𝗶𝗻𝗮𝘁𝗶𝗼𝗻 – Weak-grid voltage control and relay integration.  - 𝗦𝘂𝗽𝗽𝗹𝘆 𝗰𝗵𝗮𝗶𝗻 – Long-lead parts, EPC interfaces and controller updates.   𝗥𝗼𝗮𝗱𝗺𝗮𝗽  - 𝗦𝗵𝗼𝗿𝘁 (1–3 yrs) – Hybrid mix: renewables + condensers + GFM BESS. Condensers anchor VAR and faults; GFM builds stability.  - 𝗠𝗶𝗱 (3–7 yrs) – GFM-led fleet with condensers at critical nodes. Mature the “standard – testing – payment” loop.  - 𝗟𝗼𝗻𝗴 (>7 yrs) – GFM + digital protection replace most new condensers, keeping rotating back-up only where needed.   This is not about “opposing condensers” but “buying the right capability”. As the grid’s challenge shifts from “generating power” to “ensuring stability and usability”, assets must evolve from single-function to programmable multi-capability.   ✅ 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆  Australia’s system-strength strategy is entering a phase where GFM BESS complement synchronous machines – with payments finally reflecting true grid value.    🤔 𝗤𝘂𝗲𝘀𝘁𝗶𝗼𝗻  Which barrier is most critical for large-scale GFM BESS rollout – testing, fault-levels, or performance verification?   #TechToValue #GridForming #BESS

Multiphase Flow Modeling Techniques chart! 1. Particle-Based Methods: MPS & SPH   - MPS (Moving Particle Semi-implicit) and SPH (Smoothed Particle Hydrodynamics) are versatile Lagrangian approaches.   - MPS handles incompressible flows with strong surface tension, while SPH excels in simulating free-surface and highly dynamic flows. - Conservation of mass and momentum for individual fluid particles are solved, with fluid properties interpolated between neighboring particles. 2. Lattice Boltzmann Method (LBM)   - LBM is a mesh-based, mesoscopic method that simplifies fluid dynamics simulations, particularly for complex geometries.   - LBM solves the Boltzmann kinetic equation and is suitable for simulating multiphase flows with free surfaces and phase interfaces. 3. Grid-Based Methods:   - With Interface Capturing: Grid-based techniques, like Volume of Fluid (VOF) and Level-Set, track phase interfaces.   - VOF is ideal for sharp interface representation, while Level-Set offers smooth interface tracking, suitable for complex topology changes. - Conservation equations (mass, momentum) are solved along with an additional advection equation for interface capturing. 4. Grid-Based Methods:   - Without Interface Capturing: Eulerian Multiphase Model treat each phase as a separate fluid with mass and momentum equations.   - Eulerian Multiphase Model effectively captures dispersed phase behaviors by solving separate continuity and momentum equations for each phase, considering interfacial forces and phase interactions. - It solves separate continuity and momentum equations for each phase, coupled with models for dispersed phase behaviors (e.g., particle trajectories in DPM). - Discrete Phase Model (DPM): A Eulerian-Lagrangian approach used to simulate dispersed phase behavior, such as suspended particles in a continuous fluid. - DPM solves Lagrangian equations of motion for individual particles, accounting for drag, lift, and other forces, coupled with the continuous phase flow. - Discrete Element Method (DEM) is a particle-based method used to study granular materials and their interactions under various flow conditions. - DEM considers contact mechanics and collision forces between discrete particles, allowing simulations of particle packing, flow, and compaction.

⚡ The official report on the Iberian blackout confirms it was mainly a voltage instability event. The system had already experienced "intense voltage fluctuations" in the days before the incident. Wide-area oscillations prompted the system operator to increase grid meshing and reduce exports to France. These measures, unfortunately, decreased line flows, which paradoxically raised voltages due to the line charging effect, causing power plants to trip on over-voltage. This triggered a cascading failure, worsened by some plants tripping improperly before voltage limits were reached. The main conclusion from the report is a "lack of voltage control resources"; either they were poorly scheduled, or those allocated failed to provide sufficient power, despite an overall adequate generating capacity.   🔦 For the voltage control to be effective, it is important to consider the difference between high R/X and low R/X ratio systems. In high-voltage grids (transmission networks), which typically have a low R/X ratio, voltage magnitude is primarily sensitive to reactive power. Here, the voltage drop can be approximated by ignoring resistance and focusing on the reactive component. This is why traditional grid operators use reactive power to regulate voltage in these systems. Conversely, in low voltage (LV) systems and distribution networks, the high R/X ratio means voltage magnitude is more sensitive to active power injection. In these systems, the effect of resistance is significant, and the voltage drop approximation includes both active and reactive components. For instance, a PV plant can regulate voltage by reducing active power injection or providing negative reactive power, as per standards like IEEE 1547-2018. If reactive power alone is insufficient, active power control, which involves elements such as heat pumps, electric vehicles (EVs), or battery storage, may be necessary.   🪫 A notable point from the Iberian blackout report is the recommendation to "allow asynchronous installations to apply power electronics solutions to manage voltage fluctuations." This indicates that the voltage control capabilities of inverter-based resources (IBRs) were not fully utilised. Although IBRs offer considerable potential, challenges persist, particularly for real-time smart inverter Volt/Var Control (VVC). These include susceptibility to control instability caused by incorrect parameter selection, as smart inverter settings are sensitive to feeder configuration and operating conditions. An inappropriate droop (slope) setting can lead to control instability or voltage oscillations. There is an inherent trade-off between maintaining control stability and achieving accurate set-point tracking, which can cause voltage violations. Additionally, the non-adaptability of droop VVC to changing conditions can hinder deployment. #blackout #renewables #gridmodernization #powerelectronics #gridforming #voltage #cleanenergy

𝗦𝘁𝗮𝗿𝘁𝗶𝗻𝗴 𝗮𝗻 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗮𝗹 𝗖𝘆𝗯𝗲𝗿𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗣𝗿𝗼𝗴𝗿𝗮𝗺 𝗳𝗿𝗼𝗺 𝗦𝗰𝗿𝗮𝘁𝗰𝗵? 𝗛𝗲𝗿𝗲’𝘀 𝗠𝘆 𝗥𝗼𝗮𝗱𝗺𝗮𝗽 Industrial operations run our daily lives—think metro trains, water systems, power grids, even the checkout at your supermarket. All of this is powered by Operational Technology (OT), which directly impacts physical processes and public safety. But OT systems are under attack more than ever. Many still run on 20-year-old software, are tough to update, and can’t just be “patched” like regular IT systems. Real-world consequences can be huge: from power outages to critical failures in hospitals and transport. So, where do you even begin with OT security? Here’s my take (as discussed with Prabh in his latest podcast): 1. Understand What You Have: Start with an asset inventory. Visibility is everything. You can’t protect what you don’t know exists. 2. Identify Risks: Figure out what could go wrong. Every asset, old or new, has its own risks—especially those running legacy software. 3. Involve Your Operations Team: OT staff are focused on keeping the plant running. Bring them into the conversation from Day 1. Awareness and buy-in are key. 4. Tailor Your Approach: There’s no copy-paste. Every factory, plant, or substation is unique. Build processes that fit your environment, not just what the textbook says. 5. Prioritize the Basics: ✏️ Incident response plans: Who does what when things go wrong? ✏️ Control remote access: Limit those USB sticks, dongles, and remote sessions. ✏️ Access control: Don’t give everyone full admin rights. ✏️ Network segmentation: Create “islands” to limit the spread if something goes wrong. ✏️ Training: Make cybersecurity real for your OT staff. One weak link can break everything. 6. Use the Right Frameworks: IEC 62443 is a great start, covering people, process, and technology. Pair it with industry guidance like NIST 800-82. 7. Continuous Improvement: Cybersecurity isn’t a one-off project. Monitor, learn, and adapt. OT threats evolve—your defenses should too. Why does all this matter? Because OT is critical. Downtime isn’t just about lost money—it can risk lives. And with more cyber threats targeting OT, our collective vigilance matters now more than ever. I’ve built the OT Security Huddle community for this reason: to share, discuss, and solve real OT security problems together. Whether you’re just getting started or deep into your journey, you’re not alone.

The 28 April #blackout impacting #Spain and #Portugal is yet another reminder of the complexities we face in modern #powersystems. It is still too early to pinpoint the exact cause, initial analysis (and many excellent posts here) points towards subsynchronous #oscillations across the European network leading to sequential generation disconnections (have we seen this before South Australia?), ultimately tripping the critical France-Spain interconnector and resulting in a total system loss.   Such events inevitably bring greater focus to #GridForming (GFM) converters essential in weaker systems like Australia's but increasingly relevant even in strong grids like the European due to their oscillation damping capabilities.   Yet, as promising as #GFMs are, it is crucial to acknowledge their inherent limitations. After all, they're still #powerelectronics #converters. They have their own [power] comfort zone, they are serious about their [current] boundaries and they do sometimes have commitment [#synchronisation] issues 😁 .   Our recently published work highlights some of these limitations: 1. Synchronisation challenges: GFM converters are prone to synchronisation instability when active power references cannot be reached due to limits in the converter current and the requirement for current limiters. This can lead to instabilities in GFM converters after being subjected to large frequency disturbances as the current limiter restricts the power transfer capability of GFM converters. Our work led by Tony Xu can be found here: (Composite Power-Frequency Synchronization Loop for Enhanced Frequency Response Considering Current and Power Limits of Grid-Forming Converters: https://lnkd.in/gJhNZ9DB )   2. Effective Damping of GFMs under power and current limitations: While we can design the GFM with a certain damping coefficient in its control, power limiters will reduce the available damping power during large disturbances. This might lead to frequency / power oscillations due to insufficient damping against what we originally designed. In a worst-case scenario, the damping power can drop to zero if a fully loaded GFM converter needs to respond to a frequency drop. The work led by Shan Jiang, Ye Zhu demonstrated such occasions (Bandwise Power-Synchronization Loop for Frequency Response Improvement in Grid-Forming Converters: https://lnkd.in/gUTKxnta)   Phase Jumps: In #GFL systems, a larger phase jump typically means worse conditions for the converter. However, the synchronisation modes of GFMs set different requirements, and smaller phase jumps closer to a critical angle can actually create worse conditions for a GFM converter (more on this from Shan in June 😊 )   Such incidents underscore the urgent need to rethink grid connection standards and consider mandating site-specific testing for increasingly power electronics-defined power systems. #gridintegration #renewables #stability

As power systems transition toward higher shares of Inverter-Based Resources (IBRs), traditional Root Mean Square (RMS) models are no longer sufficient to fully capture the dynamic interactions between converters and the grid. ✓ RMS models provide averaged, simplified representations that are effective for conventional synchronous machines. ✓ However, IBR control dynamics — such as phase-locked loops (PLL), fast inner control loops, and ride-through strategies — can lead to sub-synchronous oscillations, control interactions, or stability issues that RMS models simply cannot detect. This is where Electro-Magnetic Transient (EMT) models become indispensable EMT simulations operate at microsecond-level time steps (10–20 µs) and include detailed switching and control behaviours. They allow engineers to: ▪️Analyze sub-synchronous oscillations and converter-grid interactions. ▪️Validate protection schemes under unbalanced faults. ▪️Accurately assess plant performance during disturbances. ▪️Ensure interoperability between multiple IBR technologies (e.g., hybrid BESS + PV). In essence: ▪️RMS = quick overview. ▪️EMT = high-resolution “slow-motion” insight into system dynamics.

The grid-forming failure mode the industry hasn’t hit yet isn’t a single misbehaving inverter. It’s several grid-forming units interacting, and the standard study isn’t built to see it. Almost every grid-forming study models one converter against a simplified grid. That checks whether the unit is stable on its own. It says nothing about what happens when the grid on the other side is itself a second grid-forming source, with its own controls and possibly another vendor’s firmware. Two voltage-forming sources sharing a network have to divide power by adjusting their angles relative to each other. That’s a feedback loop, and feedback loops can oscillate. The result can be power swinging back and forth between units at a low frequency, or resonances between their control loops that don’t exist when either runs alone. A mix of vendors makes it more likely, because each was tuned for stability against a passive grid, not against the other. This is the same kind of problem that has already caused real events with grid-following fleets. Grid-forming penetration is only now reaching the level where multi-unit effects start to matter. What to test before it bites: simulate multiple distinct units rather than one averaged one, include mixed vendors and tunings, and analyze how each unit’s behavior interacts with the rest. The single-unit study is necessary, not sufficient.

Here I attached the Cybersecurity Technology Stack. This poster is a complete visual guide to the key cybersecurity tools and technologies across all major categories from SIEM, EDR, XDR, SOAR, TIP, PAM, CSPM to deception technologies, UEBA and more. I created this to help professionals and newcomers get a clearer picture of what solutions are available and how they fit into the larger cybersecurity ecosystem. When I first started working in cybersecurity operations, most environments focused heavily on perimeter defence and endpoint protection. But attackers have evolved. Today, a proper setup requires multiple integrated layers that work together. No single tool is enough. What matters is how these tools connect to give visibility, control and speed in detection and response. If you're building or reviewing your cybersecurity stack, these are the key areas I recommend you consider: 1. Visibility with SIEM •Start with a strong SIEM platform. This will collect logs across your infrastructure from endpoints, firewalls, cloud and identity systems and help detect patterns or anomalies. 2. Real-time Threat Detection with EDR or XDR •Next, deploy EDR to get deep visibility into endpoint activities. If your budget allows, move towards XDR to combine endpoint, network and cloud telemetry into one detection layer. 3. Response Automation with SOAR •As alerts come in, you need a fast and consistent way to respond. A SOAR platform can automate triage, enrich alerts with threat intel and reduce the time analysts spend on manual tasks. 4. Threat Intelligence Integration •No matter how good your SIEM or EDR is, you need context. Use Threat Intelligence Platforms (TIP) to enrich data with external threat indicators and insights. 5. Secure Privileged Access with PAM •If an attacker gets access to a privileged account, the damage can be severe. Implement PAM to secure, manage and audit access to critical systems and credentials. 6. Vulnerability Management •A well-monitored environment still becomes weak if patching is not managed. Use vulnerability scanners and patch management systems to identify and remediate weaknesses quickly. 7. Cloud Security Posture and Identity Management •As more workloads move to the cloud, ensure you have CSPM tools and proper IAM controls in place to prevent misconfigurations and abuse of identity-based access. 8. Advanced Detection with NDR, UEBA, and Deception •For mature setups, consider adding Network Detection & Response, User Behaviour Analytics and deception technologies. These give you deeper layers of defence and help detect stealthy attacks. Building a modern cybersecurity setup is not about chasing tools, but designing an architecture where each solution complements the other. You want detection, correlation, automation and response to happen as smoothly as possible. This is the mindset behind the stack I designed. Every component in this poster plays a role in defending against modern threats.

The Cybersecurity and Infrastructure Security Agency (CISA), together with other organizations, published "Principles for the Secure Integration of Artificial Intelligence in Operational Technology (OT)," providing a comprehensive framework for critical infrastructure operators evaluating or deploying AI within industrial environments. This guidance outlines four key principles to leverage the benefits of AI in OT systems while reducing risk: 1. Understand the unique risks and potential impacts of AI integration into OT environments, the importance of educating personnel on these risks, and the secure AI development lifecycle.  2. Assess the specific business case for AI use in OT environments and manage OT data security risks, the role of vendors, and the immediate and long-term challenges of AI integration 3. Implement robust governance mechanisms, integrate AI into existing security frameworks, continuously test and evaluate AI models, and consider regulatory compliance.  4. Implement oversight mechanisms to ensure the safe operation and cybersecurity of AI-enabled OT systems, maintain transparency, and integrate AI into incident response plans. The guidance recommends addressing AI-related risks in OT environments by: • Conducting a rigorous pre-deployment assessment. • Applying AI-aware threat modeling that includes adversarial attacks, model manipulation, data poisoning, and exploitation of AI-enabled features. • Strengthening data governance by protecting training and operational data, controlling access, validating data quality, and preventing exposure of sensitive engineering information. • Testing AI systems in non-production environments using hardware-in-the-loop setups, realistic scenarios, and safety-critical edge cases before deployment. • Implementing continuous monitoring of AI performance, outputs, anomalies, and model drift, with the ability to trace decisions and audit system behavior. • Maintaining human oversight through defined operator roles, escalation paths, and controls to verify AI outputs and override automated actions when needed. • Establishing safe-failure and fallback mechanisms that allow systems to revert to manual control or conventional automation during errors, abnormal behavior, or cyber incidents. • Integrating AI into existing cybersecurity and functional safety processes, ensuring alignment with risk assessments, change management, and incident response procedures. • Requiring vendor transparency on embedded AI components, data usage, model behavior, update cycles, cybersecurity protections, and conditions for disabling AI capabilities. • Implementing lifecycle management practices such as periodic risk reviews, model re-evaluation, patching, retraining, and re-testing as systems evolve or operating environments change.
