Research on black-start scheme of power system with DC terminal location considering aftereffects
Based on the analysis of the relationship between the transmission capacity of the high-voltage direct current channel and the strength of the end-connect system, the influence of the coverage degree of the end-connected AC system and the total no-recovered load of the charged node on the safety and feasibility of the DC power increase in the late stage , this paper designs a black-start scheme of power system with DC terminal location considering aftereffects. The optimization goals are as follows: the total generation output in the early stage is as much as possible, the system operation is as safe and reliable as possible when the DC power is increased and the feasibility of DC power greatly rapid increase is as high as possible in the late stage. Then the mixed particle swarm optimization algorithm and Dijkstra algorithm are combined to solve the Pareto optimal solution set when all the constraints are taken into comprehensive consideration. Then triangular fuzzy number and anti-entropy method are used to determine subjective and objective weights, the Pareto optimal solution is sorted by the modified technique for order preference by similarity to ideal solution(M-TOPSIS) to determine the most satisfactory restoration scheme. In the end，effectiveness of the proposed method is validated by the optimization results on the New England 10-unit 39-bus power system with DC terminal.
