分布式可再生能源接入对配电网电压分布的影响分析

Influence of Voltage Distribution of Distributed Renewable Energy Access on Distribution Network

分布式可再生能源在中低压配电网的广泛应用,对配电网产生一定的影响。线路由单一电源变为多电源,线路电压也发生了变化。通过对分布式可再生能源接入后的中低压配电网电压变化进行理论分析,结合仿真算例,对不同接入位置、不同接入数量、不同接入容量的分布式可再生能源接入的中压线路分布情况进行分析,得到分布式可再生能源接入位置、数量及容量对线路电压分布的影响方式。

The wide application of distributed renewable energy in the middle and low voltage distribution network has a certain effect on the distribution network.The line has changed from a single power supply to a multi-power supply,and the line voltage also has changed.In this paper,through theoretical analysis on the voltage in the low voltage distribution network changes after the access of distributed renewable energy,combined with the simulation example,the distribution of voltage of the distributed renewable energy access with different access locations,different number of access and different access capacity is analyzed.The impact of distributed renewable energy access location,quantity and capacity on the line voltage distribution is obtained.
