摘　　要：分别从线路潮流、网络损耗、电网静态电压稳定性、电能质量以及系统保护等方面,研究分散发电对电力系统运行造成的各种影响。以光伏发电为例,论证分散发电对配电系统总体影响的情况。案例研究表明,适度的分散发电能给电力系统带来诸如减少输电损失、降低生产成本、推迟发电容量、输配电容量投资等方面的好处。The various impacts of distributed generation on power system operation were studied in the aspects of power flow, network loss, static voltage stability, power quality, and system protections. The case of photovohaic generation was used to analyze the general influence of distributed generation on the distribution system, and the results showed that an appropriate size of distributed generation was beneficial to line loss reduction, cost decrease, and postponing investment in generation, transmission, and distribution capacity.
