摘　　要：为提高风光互补发电系统效率、降低建设成本和增强供电可靠性,提出一种系统优化配置的设计方法。综合考虑风力发电和光伏发电出力的相关性及储能蓄电池寿命等因素,建立以系统发电成本最低为目标和以负载失电率为约束条件的优化函数,用改进和声搜索算法对目标函数进行优化。整个求解过程通过二次优化完成,在初次优化结果的基础上,对得到的风电机组功率根据市场实际情况进行修正,然后对目标函数重新优化,最终得到光伏发电和储能装置容量的优化结果。通过实例对提出的优化配置方法进行模拟验证,结果表明经过优化配置后的风光互补发电系统能够满足负载供电需求并降低建设成本。In order to improve the utilization efficiency and reduce reliability for wind power and solar power hybrid systems, an optimal construction costs as well as enhance power supply configuration method is proposed in this paper. The correlation between wind power and solar power as well as the life of energy storage battery are comprehensively considered, so an optimization function that contain optimization object with the lowest cost of power generation and constrained condition with the loss of load probability is established. An improved harmony search algorithm is used to optimize objective function. The process of to obtain solution is completed for two times optimization. After initial optimization results are obtained, the capacity of wind power is revised according actual rated power in the market. Then the objective function is optimized again. Finally, the capacity of solar power and energy storage device is obtained. An example is done to prove the correctness of the proposed method of optimal configuration. The results showed that the proposed method makes the designed wind power and solar power hybrid systems to meet the load demand for power supply and reduce construction costs.
