摘要
针对光伏微网中混合储能的容量优化配置问题,以经济性为目标考虑微电网和大电网的交互功率成本建立系统经济优化模型,并提出一种改进的多目标乌鸦算法进行求解,获得优化配置结果。考虑分时电价设计微电网的系统运行策略,建立系统的运行成本模型,在此基础上建立不同类型储能介质的投资模型。利用以经济最优为目标,获得不同类型储能介质的容量优化配置占比,并对比多目标粒子群算法进行算例验证。结果表明提出的IPMOCSA求解精确度更高、收敛速度更快,混合储能配置成本节省了5.13%,配置方法对实际应用有一定参考性。
Aiming at the capacity optimization allocation problem of hybrid energy storage in photovoltaic micro-grid,the system economic optimization model was established by taking the interactive power cost of micro-grid and large grid as the objective,and an improved multi-objective crow search algorithm is proposed to solve the problem and obtain the optimal allocation results.Considering the time-of-use electricity price to design the system operation strategy of the micro-grid,establish the operating cost model of the system,and build the investment model of different types of energy-storing media.Using improved multi-objective crow search algorithm as the goal of economic optimization,the optimal allocation ratio of different types of energy storage media is obtained,and the multi-objective particle swarm optimization is used to verify the examples.The results show that the proposed improved multi-objective crow search algorithm solution has higher accuracy and convergence speed.The cost of hybrid energy storage configuration is saved by 5.13%,and the configuration method has certain reference for practical applications.
