Study on credibility theory-risk evaluation of Henan grid transfer capability
摘要
Abstract
The uncertainty of electrical power load has much effect on power grid's transfer capability. From the point of spreading synthetical load model by State Grid Company, a risk assessment algorithm based on credibility theory for power grid's transfer capability is developed, which is based on the risk source of uncertainty of electrical power load parameter. The risk aroused by uncertainty of electrical power load parameter is investigated, including sensitivity/adaptability analysis of load parameter, grid's transfer capability limit, load parameter's expected value model of fuzzy-random variable, and grid's transfer capability risk assessment. The simulation result of Henan grid indicates that the algorithm can assess the risk of Henan grid's transfer capability from the view of security and economics, and it is important to the security and reliability of Henan grid.关键词
