Abstract:

This paper focuses on the distributed wind power generation system; photovoltaic power generation system and battery storage system, in the active distribution network. Based on the selected decommissioned power batteries, the capacity configuration model of the distributed power supply and battery storage system is established, which aims at the whole system cost, system load shortage rate, and new energy waste rate. To address these issues, an improved harmony search algorithm is. Through the simulation analysis, the rationality of the retired battery management strategy and the effectiveness of the improved harmony search algorithm is verified. Both the distributed power supply and battery storage system can be optimized at the same time, which can not only effectively support the operation of the distribution network and improve the energy utilization rate but also reduce the cost of economic allocation. Considering the wind speed, solar irradiance, and load demand data of the summer typical day and winter typical day in an active distribution network, the multi-objective optimal allocation model includes the allocation of capacity and cost of the distributed generation and energy storage system, new energy abandoned power rate and loss of power supply probability. The improved harmony search algorithm is used to solve the problem. Finally, the correctness and effectiveness of the harmony search algorithm and optimal allocation model are verified by the configuration results.

Key words: outdated battery, second-use, battery storage system, multi-objective optimization, improved harmony search algorithm
