Battery Energy Storage Systems (BESS) for Grid Sustainability, Stability, Reliability, and Resilience

Battery energy storage systems (BESSs) are critical for integrating renewable energy, supporting data center growth, and enhancing grid performance, with AI/ML approaches enabling efficient, chemistry-flexible state monitoring and health prediction. Key advances include improved SOC/SOH estimation, grid-forming controls, safer architectures, and tools for co-optimizing BESS with other energy sources and demand-side flexibility.

Behind-the-meter DC Microgrid

Behind-the-meter DC microgrids can boost efficiency, resilience, and renewable use—especially in data centers—by simplifying power conversion and resource integration, though they also pose challenges with protection, grounding, and AC system compatibility.

Flexible Loads

As energy systems face new challenges beyond peak demand, customer-side solutions are evolving into flexible load programs and virtual power plants, integrating customers directly into grid operations.

Inverter Based Resource (IBR) Modeling

Accurate modeling of Inverter Based Resource (IBR) plants in power system studies is essential for planning and the secure operation of power systems. The IEEE Power & Energy Society (PES) provides technical resources and opportunities for industry professionals to stay informed and engaged in IBR modelling.

Machine Learning for Microgrids: Resiliency, Stability, Control, and Operation

Microgrids are a critical component of the electrical grid energy transition. Concurrently, machine learning applications to smart grids have received significant attention in recent years. This Trending Technologies explores the dynamic intersection of the two technologies: microgrids and machine learning advancements.

Microgrid Protection

Microgrids require control and protection systems. The design of both systems must consider the system topology, what generation and/or storage resources can be connected, and microgrid operational states (including grid-connected, islanded, and transitions between the two).

Earthing of Marine Systems

Earthing (grounding) of maritime systems (waterborne vessels and ports) is an interesting issue with significant specificities in comparison with inland cases, but also with a significant impact on normal steady-state operation.
