考虑含分布式电源的城市配电网损耗边界值研究

Research on the Boundary Influence of Urban Distribution Network Loss with Distributed Generstion

为了在配置分布式电源(DG)时,尽量减小接入对电网的不利影响,从配电网网损的角度,对分布式电源接入城市配电网网损影响的边界条件进行定量分析,得出相关影响规律,给出了降低含分布式电源的配电网网损的相关建议。以某实际供电馈线为例,进行了仿真验证。

The influence of the distributed generation( DG) accessed to the distribution network has been paid closely attention to the grid operating unit. It is one of the key work for new energy access that how to configure the distributed power to reduce its adverse impacts on the power grid. From the perspective of the power distribution network loss,the calculation method of the network loss was studied before and after the distributed power accessed.The boundary conditions on the network were analyzed and the regularity of influence was got. Also the advices on reducing the network loss were given when the DG accessed by the influence regularity. And a practical power feeder line in Guangxi was taken as an example to verify the research result by simulation.
