摘要
含风、光、储的独立微电网,科学配置合理的储能容量,能满足负荷供电需求,保证系统安全稳定运行。针对三种具有代表性的应用场景,分别提出了储能系统配置评价指标;以储能系统全寿命周期费用最优为优化目标,计及系统运行要求及蓄电池设备的特性约束,建立了孤网运行的微电网蓄电池储能系统的优化配置模型,并采用改进的粒子群算法进行求解;在容量配置的基础上,探讨了储能系统拓扑结构优化的方法。编写了优化设计软件并进行算例验证。
For an independent microgrid containing wind power,photovoltaic power and energy storage system,it is of great importance to configure reasonably the capacity of energy storage system to meet the electric power need of load and to make the microgrid system function safely and stably.Aiming at three typical scenarios,different indexes were presented.An optimal sizing method based on the modified particle swarm optimization was proposed.The method solves the optimal design problem on the premise that microgrids function safely.Various restrictions of batteries were taken into account,and finally the best sets of batteries were selected to achieve the optimal economic.In addition,the optimal design of topological structure of energy storage system was discussed.And optimization software was programmed and verified by calculation examples.
