独立光伏发电混合储能系统容量优化研究

摘要

准确建立系统中各环节数学模型,综合考虑不同储能元件(超级电容器和蓄电池)的储能特性,以混合储能系统成本最低为优化目标,以独立光伏发电系统各项运行技术指标为约束条件,提出了一种基于单纯形法的容量优化配置方法,并进行了编程实现和算例验证.%Accurate mathematical models of all sectors in the system are established, and the different characteristics of energy storage elements (super-capacitors and batteries) are considered. A capacity optimization method based on simplex is proposed considering the lowest cost of hybrid energy storage system as the optimization objective, and with the technical indicators of independent photovoltaic power generation system as the constraints. And it is realized by programming proved by numerical example.
