Have you ever considered how challenging it is to optimize the performance of switched reluctance generators while keeping both efficiency and torque quality in balance? The recent publication in Eletrônica de Potência (Open Journal of Power Electronics) introduces a performance optimization procedure for switched reluctance generators operating below base speed, in the current-controlled region. The approach determines optimal firing angles using a particle swarm optimization (PSO) algorithm, designed with a cost function that balances reduced torque ripple with improved energy efficiency. The study also compares the method with a traditional exhaustive search algorithm, showing how PSO drastically reduces computational complexity. In addition, an original statistical analysis highlights the consistency of the results, and experimental validation demonstrates the effectiveness of the proposal in a wind energy conversion system. This work brings an innovative and practical perspective to optimization in renewable energy systems and electric machines.

⚡ Why Synchronous Condensers Are Making a Comeback As our power grids evolve with renewable integration, one “classic” technology is quietly becoming critical again: Synchronous Condensers (SCs). Think of them as the unsung heroes of the modern grid. Unlike generators, they don’t produce active power — but they deliver invaluable services: ✅ Voltage stability: by dynamically supplying or absorbing reactive power ✅ Short-circuit strength: essential for grid protection systems ✅ Inertia support: stabilizing frequency during disturbances With the rise of inverter-based resources (IBRs) like solar and wind, traditional system inertia and fault levels are declining. SCs are stepping in to bridge that gap, ensuring reliability and resilience — especially in regions rapidly shifting toward renewables. What’s exciting is that utilities worldwide are now combining SCs with STATCOMs and advanced controls, creating hybrid solutions that balance fast response with mechanical inertia. 👉 In many ways, the grid of the future is learning to stand on the shoulders of this century-old technology. 💡 Question for you: Do you see synchronous condensers as a temporary bridge until grid-forming inverters dominate, or a long-term backbone of stable grids? #PowerSystems #SynchronousCondenser #GridStability #RenewableEnergy

🔋 ⚡ 💻 Because of the greenhouse effect and other pollutants, the production of electricity from traditional energy sources has been causing serious environmental problems in recent years. Numerous strategies have been proposed to address climate change and environmental damage. Implementing a microgrid based on renewable energy sources is one of the important methods because of its high efficiency and ease of use, as well as the fact that it has been essential to the production of clean energy. Microgrids with integrated renewable energy sources are becoming more and more important in the fast‐changing electrical energy production scenario. In a recent study just published in Energy Science & Engineering Wiley, we proposed an adaptive sliding mode controller based on third‐order fuzzy logic which can eliminate disturbances by default without the need to know their limits. We examined a hybrid alternating current/direct current microgrid that uses renewable energy sources, such as a 33 Ah storage battery, a 4.5 kW solar system, and an 8 kW wind turbine. The primary goal was to use an intelligent control technique based on type‐3 fuzzy sliding mode control to increase the direct current link voltage stability during islanding scenarios.

🔌 Grid-Following Inverters: The Technical Backbone of Modern Grids Grid-following inverters are the fundamental components enabling today's rapid integration of renewable energy sources. Their primary function is to act as a controlled current source, injecting power into the grid while strictly adhering to its existing conditions. The core of a grid-following inverter's operation is its ability to synchronize with the grid using a Phase-Locked Loop (PLL). The PLL ensures the inverter's output is perfectly aligned with the grid's voltage. This synchronization is captured by the relationship: Vgrid =Vm ⋅ cos(ωt+θ) [1] Here, Vm is the grid voltage magnitude, ω is the angular frequency, and θ is the phase angle, which the PLL tracks precisely. Based on this, the inverter's controller generates the current reference signals (Idref, Iqref) in a rotating reference frame (d-q frame) to control active and reactive power flow: ● Active Power (P): Controlled by the d-axis current. P = 3 ÷ 2 (Vd ⋅Id + Vq ⋅ Iq ) [2] ● Reactive Power (Q): Controlled by the q-axis current. Q = 3 ÷ 2 (Vq ⋅ Id −Vd ⋅ Iq ) [3] ● In grid-following mode, the inverter aligns its d-axis with the grid voltage vector, making Vq approximately zero. This simplifies the power equations to: P≈ 3 ÷ 2 (Vd ⋅ Id) [3] Q≈ - 3 ÷ 2 (Vd ⋅ Iq) [4] ● This allows for the independent control of active power (via Id ) and reactive power (via Iq), enabling the inverter to follow grid commands. ● Conclusion: While a highly effective strategy for today's centralized grids, grid-following inverters are dependent on a strong grid for stability. The rise of renewables is changing this, paving the way for #gridforming solutions that can create their own stable voltage and frequency. What are your thoughts on the future balance between grid-following and grid-forming technologies? 🤔 Will they coexist, or will one eventually dominate? #PowerElectronics #GridFollowing #RenewableEnergy #ElectricalEngineering #SmartGrid #PowerSystems #EnergyTransition
