【摘要】：分布式电源(DER)与配电网之间以及DER之间的通信不畅,会导致DER并网后对电网的电能质量、继电保护、孤岛问题产生不利影响,进一步影响整个电网的经济性和安全性。文中综合考虑技术性、经济性、适应性、扩展性和对DER的支撑性,设计了一种DER并网监控的解决方案,并提出了含DER的配电网通信方式适应性评价指标体系。根据DER并网监控通信需求,提出一种模糊一致的层次分析评价方法,并选择多种通信方式进行适应性评价。该评价方法结合了主客观需求,为含DER并网的配电网通信平台建设提供了可行性依据。
[Abstract]:The communication between (DER) and distribution network and between DER and distributed generation is not smooth, which will lead to the negative influence on the power quality, relay protection and isolated island of the power network after the DER is connected to the grid, and further affect the economy and security of the whole power network. Considering technology, economy, adaptability, expansibility and support to DER, a solution of DER grid-connected monitoring is designed, and an index system for evaluating the adaptability of distribution network communication mode with DER is put forward. According to the communication requirement of DER, a fuzzy and consistent AHP evaluation method is proposed, and a variety of communication methods are selected for adaptability evaluation. The evaluation method combines the subjective and objective requirements and provides a feasible basis for the construction of distribution network communication platform with DER.
