摘要
With a large number of distributed generations integrated,the power supply structure and operating mode of traditional distribution network have changed. Researching the influence factors of operation risk for distribution network with distributed generations is helpful to improve the safety and reliability of power grid. The probabilistic models of distributed generation intermittent output and load demand are established. Monte Carlo method is used to simulate random operation scenarios,Cholesky decomposition ordering is used to make wind speed,light intensity,load and other random variables meet the spatio-temporal correlation,represent scenarios and their probability are determined by scenario clustering,and the operation risk of distribution network is calculated. In addition,the influence factor tracing of distribution network operation risk is carried out in terms of the configuration of distributed generations and important loads,the connection position of tie lines,and the proportion of automatic control switches. © 2021, Electric Power Automation Equipment Press.
