AI Technical Summary
In existing technologies, the rotational inertia of the sending-end grid in asynchronous interconnected grids decreases, and frequency problems become prominent. The fixed control parameter strategies of energy storage and DC frequency limiting controllers (FLCs) lack adaptability, leading to frequency instability of the receiving-end grid and making it unable to adapt to disturbances of varying degrees.
By establishing a multi-scenario, multi-source frequency control parameter joint optimization method, the frequency response parameters of energy storage and FLC are dynamically adjusted. Based on the unified grid frequency model and scenario set, a genetic algorithm is used to solve the rolling optimization model to optimize the joint frequency regulation performance of energy storage and FLC.
Improve the frequency control capability of the sending and receiving power grids under large disturbance scenarios, enhance the frequency regulation economy under small disturbance scenarios, reduce the operation frequency of energy storage and FLC, and improve the system frequency stability and economy.
