Influence of the Access of Distributed Generation on the Distribution Network System of Inner Mongolia Power Grid and Countermeasure Analysis

Abstract

Solar energy resource is highly rich in Inner Mongolia regions, and the customers utilized electric are scattered in the vast grassland. Thus, the distributed generation with its unique performance and high quality, has been developed rapidly in recent years. However, the large-scale distributed power supply has brought many unpredictable impacts when they are accessed to the distribution network, even seriously affecting the safe and stable operation of the distribution network. In this work, the technical barriers caused by distributed power generation to the grid-connected have been explored. In addition, the constraints and key influencing factors of distributed generation on distribution network have also been analysed and a safe and stable operation strategy to access distributed photovoltaic power supply into the network has proposed. The results here could provide a theoretical guidance for the rapid formulation and optimization of the distributed power accessing into grid network in Inner Mongolia power grid.
