The present situation of the economic development, power demand and load characteristics of Shandong province was analyzed in this paper. The economic development was forecasted with the consideration of domestic and foreign macroeconomic situation. The total electricity consumption of Shandong province was predicted by electricity intensity, sub-industry forecast, sub-region prediction, regression...
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,...
Taking advantages of proportional-integral-differential (PID) control in voltage regulation, and those of linear optimal control in dynamic stability, a new excitation control scheme based on fuzzy logic control is proposed. The method adjusts the weights of voltage regulation tunnel and auxiliary stabilizing tunnel on-line according to different operating conditions by a fuzzy controller, aiming...
