Distribution network reliability considering weather and distribution generation
摘要
Abstract
The impact of distributed generation and adverse weather on distribution network reliability is studied. This paper illustrates a distribution network reliability calculation model considering the act of weather and DQ uses the maximum economic benefits as objective function to determine the island, and then improves the minimal path method of the traditional reliability calculation and makes it suit to calculate the distribution network reliability considering weather and DG. Four types of programs including without DG and weather, only DG, only weather, and both DG and weather are calculated and compared from the aspects of load points, feeders and system reliability indices. The calculating results indicate that the reliability of distribution network is reduced when considering weather factors, especially in adverse weather conditions, and improved in the island when DG connected. Considering both DG and weather, the reliability of distribution network can reflect the actual condition more accurately, which proves the validity of the method and the model.关键词
