Optimization method of energy storage system based on improved VSG
This paper presents a comprehensive analysis of a novel optimization method for energy storage systems under unbalanced load conditions, leveraging an enhanced control algorithm
The simulation results demonstrate that, under load disturbances, the photovoltaic energy storage system utilizing the adaptive VSG control strategy exhibits superior stability and dynamic performance. Compared to the conventional VSG control strategy, the adaptive approach significantly reduces frequency and output power fluctuations.
The storage supplies the active power to the network when the frequency drops, and vice versa. Meanwhile, the application of VSG with energy capacitor storage (ECS) system helps in smoothening the line power fluctuation caused by variable wind speed permanent-magnet synchronous generators.

The penetration of power electronic-based power generation in power grid reduces the total inertia, and thus increases the risk of frequency instability when disturbance occurs in the grid. VSG produces virtual inertia by injecting appropriate active power value to the grid when needed.
