摘要
智能配电网中引入分布式储能(Distributed Energy Storage,DES),可以减少负荷峰谷差,提高供电可靠性,降低网络损耗,改善电压质量。在满足电压、电流等约束条件的前提下,以配电线路升级改造费用最小、网络损耗费用最小以及DES总投资费用最小建立多目标优化模型,并采用国外9节点标准单辐射系统对模型进行优化配置研究。
The introduction of Distributed Energy Storage(DES)in the smart distribution network can reduce load peak-to-valley difference,improve power supply reliability,reduce network losses,and improve voltage quality.Under the premise of satisfying the constraints of voltage and current,this paper establishes a multi-objective optimization model with the least cost of upgrading and reconstruction of distribution lines,the least cost of network loss,and the least total investment cost of DES.The 9-node standard single-radiation system is used to optimize the model configuration.
