考虑分布式电源接入的配电系统典型算例设计

目前,针对未来分布式电源广泛接入配电网场景,缺乏统一、规范的典型算例。为此,结合我国配电网实际情况,构建了农村、城市和工业园区3类典型场景。在此基础上,提出了典型场景算例的设计原则和方法,并基于负荷类型、配电网典型特征、分布式电源渗透率等条件,分别设计了典型场景下的配电网算例,给出了详细的算例参数和典型日数据。同时,给出算例的分析指标与方法,从过电压/低电压测试、分布式电源消纳计算等角度进行了详细的分析测试。结果表明,所设计算例合理可行,可为分布式电源接入相关研究提供良好的案例基础。

Typical Case Design of Distribution System Considering DG Integration

At present, there is a lack of unified and standardized typical examples for the scenario that distributed generation is widely connected to the distribution network in the future. Therefore, combined with the actual situation of China’s distribution network, three typical scenarios of rural, urban areas and industrial park are constructed. On this basis, the design principles and methods for typical scenarios are proposed. According to the load type, typical characteristics of distribution network, and the penetration rate of distributed generation, the distribution network examples in typical scenarios are designed, respectively, and the detailed parameters and typical daily data are given. At the same time, the analysis index and method for the example are given, and the detailed analysis and test are carried out from the perspective of over / low voltage test and distributed generation accommodation calculation. The results show the rationality and feasibility of the design example, which can provide a good case basis for the related research of distributed generation access.
