This paper proposes a method for the optimal black-start reserve water of pumped storage. When pumped storage provides black-start ancillary service for power system, some capacity in the upper reservoir must be reserved and then the peak-load shaving benefit of pumped storage plant would be influenced. In order to make pumped storage plant bring the largest benefits to power system, a mathematical...
Power system restoration is a multi-objective problem with limited optional plans. Generally, multi-criteria decision-making (MCDM) method is employed to rank optional restoration plans and provide decision support for dispatchers. Weights set by decision-makers based on their experience may have subjectivity and then influence optional plans ranking result. In order to properly select attribute weights...
This paper presents a novel group multi-criteria decision-making method for power system skeleton restoration. The proposed method improves the technique for order preference by similarity to an ideal solution (TOPSIS) in supporting group decision-making. This method can comprehensively consider the safety margin and restoration rate of power system, and can be used to support the restoration decision-making...
Power system skeleton restoration is a typical semi-structured problem, difficult to establish accurate mathematical model to solve. Integrating heuristic rules and numerical calculation with genetic algorithm, the method for skeleton restoration scheme generating of every subsystem is proposed. In this method, fitness value is given by numerical calculation and global optimization is realized by...
Power system skeleton restoration is a typical semi-structured problem and difficult to establish accurate mathematical model. Constrains such as transient overvoltages, sustained power frequency overvoltages, self-excitation, and restoration duration are comprehensively considered in this paper. A model of group intelligent decision support system for power system skeleton restoration is constructed,...
