Research on the Abnormal Discontinuation of Active Distribution Network with Comprehensive Risk and Benefit

The risk, cost and profit factors of the automatic distribution network are analyzed in this paper, based on which, the multi-objective optimization model is established by evaluating the risk of the restoration sub-process, the restoration control cost and the restoration benefit. The heuristic algorithm based on the greedy strategy is used to optimize the distribution network restoration problem. The simulation results show that the abnormal outage restoration strategy of this paper can take into account the uncertain risks in the process of distribution network restoration and maximize the power supply in the power loss area under the premise of maximizing the economic restoration benefit, Thereby improving the reliability of the distribution network and the economics of the restoration process.
