| Abstract:The scale of new energy grid-connected power generation in the distribution network become more and more common, but the intermittency and uncertainty of the new energy output power will have a great impact on the power quality of the distribution network. Based on the analysis of new energy output power characteristics, the influence principle of power quality of distribution network caused by new energy grid-connection is analyzed. The power quality simulation calculation model of distribution network is established, simulation calculation of the node voltage deviation and the total harmonic distortion rate of the node voltage under the situation that the new energy is connected to the network at different locations and capacities and under the different ways of multiple new energy sources. The research results of this paper can provide effective theoretical guidance and reference for new energy grid-connected power generation and power quality optimization of distribution network. |
