摘要
针对独立供电的微电网,分析后备电源电池储能、超级电容器、柴油机的运行策略,以此为基础提出微电网内考虑混合储能系统成本的最大化可再生能源利用率、最大化电池储能使用寿命和最大化因减少柴油机运行而减少的环境效益为优化目标函数的混合储能优化配置模型,并通过多变异位自适应遗传算法求得多元复合储能系统容量的优化配置。通过仿真计算验证所提策略的正确性与有效性。
For the stand-alone microgrid, this paper analyses the operation strategy of multi-element composite energy storage system, which includes batteries, super-capacitors and diesel engines. Considering the cost of such a composite energy storage system in microgrid, an optimal allocation model is presented for maximizing the utilization ratio of renewable energy, the lifespan of batteries and the environmental benefits brought by reducing diesel operation time. An adaptive multiple bit mutation genetic algorithm (GA) is adopted to achieve the global optimal solution and figure out the capacity of multi-element composite energy storage system. The validity and effectiveness of the proposed strategy are finally verified by the simulation calculation.
