With more and more renewable energy resources integrated into the power grid, the system is losing inertia because power electronics-based generators do not provide natural inertia. The low inertia will cause the microgrid to be more sensitive to disturbance and thus a small load change may result in a severe deviation in frequency. Based on the basic VSG …

Battery energy storage performance in microgrids
Battery system consists of a charge controller, a bank of batteries, protection devices, possibly a DC-DC converter, and the wiring that attaches the battery system to the microgrid. Each battery is a collection of cells with a common electrolyte and specific material for the anode and cathode poles.
A microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a mission-critical site or building. A microgrid typically uses one or more kinds of distributed energy that produce power. In addition, many newer microgrids contain battery energy storage systems (BESSs), which, when paired
