含分布式电源配电网可靠性的评估方案研究

A study of reliability assessment schemes of distribution network with DGs

在原有配电网引入分布式电源的情况下,提出一种基于应用改进最小路法结合可靠性指标求解评估含分布式电源distributed generation(DG)的配电网可靠性评估方案。以IEEE-RBTS Bus6系统为例进行不同方案的仿真。仿真结果表明,所提出的可靠性评估模型可以明显地改善配电网系统对用户提供电能的可靠性。

A modified minimal path method-based reliability assessment scheme（ method） of distribution network considering distributed generations（ DGs） was proposed to resolve the reliability of power grid. A distributed source model was established and power circle method was used to determine the maximum range of the island. IEEE-RBTS Bus 6 system with the island model was set as an example to verify the proposed algorithm. The results show that the reliability evaluation scheme is effective in improving the distribution network reliability.
