摘 要: | 随着分布式发电(DG)的大量接入,微电网的安全稳定运行正面临较大的考验,精准切负荷控制策略的重要性愈发突出。为了最小化过切量,提升负荷控制的经济性,需对微电网精准切负荷的控制策略进行改进。首先,介绍了智能负载原理,通过调节电力弹簧(ES)电压的大小实现智能负载功率的动态变化;然后分析了应用权重法与轮次法的传统精准切负荷控制策略,在此基础上提出了一种基于智能负载的精准切负荷控制策略,通过负荷的动态响应实现最小化过切量,并将其应用于权重法与轮次法;最后,算例分析表明,所述方法可有效降低系统过切量,提升负荷控制的经济性。

Abstract: | With the larger and larger amounts of distributed generation, the safe and stable operation of distribution network is being greatly tested, the importance of precise load-shedding control strategy is becoming more and more prominent. In order to minimize the overcutting value, and to improve the economy of load control, the control strategy of precise load-shedding in distribution network needs to be improved. At first, the traditional control strategy of precise load-shedding is analyzed; then, a new precise load-shedding control strategy based on smart loads is proposed, and applied in weight method and round method respectively; at last, the cases analysis indicate that, the proposed strategy can reduce the system overcutting value effectively, and enhance the economy of load control. |
