摘　　要：新能源并网有效缓解了我国能源短缺与环境污染问题,但新能源发电存在间歇性、波动性和不确定性,在并网时对配电网的电压影响较大,使得配电网的结构及控制更复杂。针对新能源并入10 kV配电网,重点讨论了配电网的无功电压与潮流分布特性。分析新能源并网对电压波动的影响机理,研究发现,在配电网末端并网不仅能降低新能源并网对配电网的不利影响,还能对配电网整体电压分布起一定的支撑作用,提升配电网电压合格率,保障配电网供电质量。The integration of new energy into the grid has effectively alleviated the energy shortage and environmental pollution problems in China.However,the output of new energy is intermittent,fluctuating,and uncertain,which has a significant impact on the voltage of the distribution network during grid connection.At the same time,it also makes the structure and control of the distribution network more complex.Regarding the integration of new energy into the 10 kV distribution network,the distribution characteristics of reactive voltage and power flow in the distribution network were mainly discussed.Analyzing the impact mechanism of new energy grid connection on voltage fluctuations,it was found through research that grid connection at the end of the distribution network can not only reduce the adverse impact of new energy grid connection on the distribution network,but also play a certain supporting role in the overall voltage distribution of the distribution network,improve the voltage qualification rate of the distribution network,and ensure the quality of power supply in the distribution network.
