Abstract: With the expansion of distribution network construction scale and diversification of power sources, mismatches between power supply and load demand often occur, leading to high energy consumption and poor system stability. Coordinated operation of multiple power sources, such as energy storage systems and diesel generators, can effectively smooth load fluctuations and improve power reliability. This paper proposes an optimized power configuration method for distribution construction based on a microgrid–multi-source collaborative system. It uses BiLSTM to capture load and output patterns, and optimizes parameters with a fruit fly algorithm. The method improves supply-demand matching, boosts efficiency, and cuts costs, making it practical for real - world applications.
