摘要
随着分布式电源(DG)渗透率的提高,配电网运行的安全性和可靠性将面临挑战。从机理上分析了分布式电源接入对配电网电压分布、线路电流和网络损耗的影响,通过典型10 k V配电线路的仿真,研究不同分布式电源渗透率下,配电网的电压分布、线路电流和网络损耗等运行参数的变化规律,最后据此提出提升配电网分布式电源消纳能力的措施。研究成果对配电网中分布式电源的管理和规划具有重要的指导意义。
With the increase of distributed generation penetration, the safety and reliability of distribution network will face with challenges. This paper analyzes the effects of distributed generation on the voltage distribution, line current and network loss of distribution network from the mechanism, and studies the change rules of operating parameters including voltage distribution, line current and network loss with different penetrations through the simulation of a typical 10 kV distribution feeder. Finally, this paper puts forward several measures to enhance the distributed generation consumption ability of distribution network. The research results have important guiding significance for the management and planning of distributed generation in distribution network.
