Introducing energy storage units in wind and photovoltaic systems can smooth output power and enhance system schedulability. These schedulable new energy resources can provide frequency and voltage support under VSG control strategy, thereby enhancing the stability and reliability of the power system.
The model includes new energy generation, energy storage system, and VSG control module to simulate load fluctuations and their impact on frequency response. The initial state of charge of the energy storage system is set to 50%, taking into account the frequency changes and response characteristics under different operating conditions.
The hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
Energy storage systems have emerged as an ideal solution to mitigate frequent frequency fluctuations caused by the substantial integration of RES.
Energy storage system is an optional solution by its capability of injecting and storing energy when it is required. This technology has developed and flourished in recent years, since super-capacitor, compressed air energy storage system, battery energy storage system and other advanced ESS are applied in various circumstances.
The energy storage adaptive coordinated control strategy ground on VSG technology is applied in the power system. Modern computer technology are crucial for ensuring frequency stability of the power grid and improving system adaptability (Yao et al. 2023).
