Abstract: Starting with the implementation modes and significant importance of the integrated source-grid-load-storage (SGLS) system, this paper introduces the construction method of the collaborative control model for SGLS. The model is solved using an improved genetic algorithm, and simulation experiments are conducted for analysis. The research results show that by adopting this collaborative control method, the curtailment of wind and solar power in the power system is significantly reduced, the operating costs are substantially lowered, and the grid's ability to accommodate new energy sources is enhanced, which is conducive to promoting the development of the integrated SGLS system.
