用户参与互动环境下含分布式电源的复杂配电系统可靠性评估

The study on reliability evaluation in the complicated distribution system with distributed generators under the interactive environment is of great importance and urgency in promotion of clean renewal energy use and guarantee of users' safety quality power utilization. In the meanwhile, it faces huge challenges. Therefore, this project will design an interactive utilization pattern which can stimulate users' interatction and bidding, and study reliability and power equivalent model of distributed generator system incorporating correlations of power outputs, reliability and power output model of energy storage system incorporating aging failures, reliability indices and evaluation approach of micro grid considering space/time correlations and reliability equivalent model. Power resource optimization allocation model and its solution based on the principle of risk sharing are established. On the basis of studying the strategy and algorithm of dynamic islanding partition taking control policy and reactive power balance into account, the sequence and probability of the service area of distributed generators are determined; reliability indices, evaluation approach and sensitivity algorithm of complicated distribution system will be studied, in the accordance with the characters of element configuration, topological structure, and strong randomness of operation state, in order to explore the weakness of system reliability. The aim is to construct theoretical system and practical method of reliability evaluation in the complicated distribution system with distributed generators under the interactive environment, breaking through the limitation of current study methods, to help sustainable development of clean renewable energy.
