摘要
对交直流混合微电网中电源进行优化配置能够减少换流损耗,降低系统成本。针对独立交直流混合微电网特有的结构和能量流动方式,考虑能量传输效率,提出了改进的能量管理策略。优化配置模型以经济性最优为目标,综合考虑环保性和供电可靠性,采用改进的人工蜂群算法对模型进行求解,得到独立交直流混合微电网的分布式电源优化配置结果。最后,通过算例进行仿真验证,结果表明,交直流混合微电网相对于纯粹交流微电网和直流微电网能够降低系统运行成本,使用改进后的能量管理策略能得到经济性更优的微电网电源配置方案。
The optimal allocation of power supply in AC / DC hybrid microgrid can reduce the converter loss and system cost. According to the unique structure and energy flow pattern of AC / DC hybrid stand-alone microgrid,this paper proposes the specific energy management strategy with considering the power transmission efficiency. The optimal allocation model aimes at the optimal economy,and comprehensive consides environmental protection and power supply reliability. This paper adopts modified artificial bee colony algorithm to solve the model,which can obtain the optimal allocation result of distribution generation in AC / DC hybrid stand-alone microgrid. Finally,through the comparison and analysis of examples,it show s that AC / DC hybrid microgrid can save the operation costs of the system compared with AC microgrid or DC microgrid,and the application of improved energy management strategy can obtain the allocation scheme of power supply in microgrid with better economy.
