摘　　要：分布式发电是建设坚强智能电网的重要组成部分,大量分布式电源的接入会给配电网的运行、控制带来巨大挑战。针对分布式电源接入东北地区实际配电网后电压及网损的变化情况进行仿真计算,确定分布式电源的容量选择原则。通过分析不同出力、不同位置情况下电压及网损的变化情况,对实际配电网中分布式电源的选址、定容提供参考依据。Distributed generation is an important part for building a strong and smart grid. With too many distribution generations connected to the distribution system, the operation and control of it would be a tough challenge. Through simulations of voltage behaviors in a practical grid connected with large numbers of distributed generations in northeast of China, a principle is given in this paper for capacity determination of distributed generations. Guidances to the locating and capacity determining of distributed generations in practical grid are proposed through the analysis on voltage and network losses under different output powers and at different locations.
