为满足国家建设智能电网的要求,未来的新型农村电网应充分考虑分布式电源的发展,实现分布式电源与配电网的互动。针对未来分布式电源在农村电网中应用的可能性,提出了用序优化理论结合二次电流矩粗糙估计的方法来解决配电网中分布式电源的选址和定容问题,并对某农村6k V24节点配电网系统进行了测试分析,结果证明该方法能够有效地确定分布式电源的接入位置和容量,接入后网损减小且对电压有支撑作用。
In order to meet the national requirements of building smart grid, the new rural power grid in the future should fully consider the development of distributed power and realize the interaction between distributed power and distribution network. Aiming at the possibility of applying distributed power in rural power grid in the future, a method of order optimization theory combined with the estimation of secondary current moment is proposed to solve the problem of location and capacitance of distributed power in distribution network. 6k V24 node distribution network system is tested and analyzed. The results show that this method can effectively determine the access location and capacity of distributed power supply, reduce the network loss after access and support the voltage.
