摘要
主动配电网的提出为分布式电源的高渗透率接入提供了有效的解决方案,控制运行方式的改变使得主动配电网运行模式下微电网的运行与传统微电网有所出入,分析了主动配电网运行模式对微电网可靠性的影响,构建元件的可靠性模型,探讨了基于蒙特卡罗模拟的含微电网的主动配电网可靠性评估方法,并对改造后的IEEE RBTS系统进行可靠性评估,对比分析在不同情境下的系统可靠性。算例的评估结果表明,微电网在主动配电网的运行模式下更能提高其可靠性。
The active distribution network （ADN） provides an effective solution for the high penetration of distributed generators. The change of control and operation mode has made the microgrid operation different from that in traditional mode. In this paper, the influerice of ADN operation mode on the microgrid reliability was analyzed and a reliability model of component was built. Based on Monte Carlo simulation a reliability evaluation algorithm for ADN containing microgrids was discussed, and the reliability of modified IEEE RBTS was evaluated with this algorithm. Moreover, the system reliability in different situations were compared and analyzed. The evaluation results have shown that microgrids in the ADN operation mode will effectively improve the power supply reliability.
