Multi-objective Optimization for Short-circuit Current Limitation Schemes in Multiple DC Infeed Power Systems
摘要
Abstract
Based on the multi-infeed short circuit ratio,the influence on multi-infeed short circuit ratio caused by current limiting measures is analyzed,and a mathematical model of multi-objective optimization for short-circuit current limitation schemes is developed.The objective functions considering the voltage support ability,the costs of limitation schemes and short-circuit capacity margin are presented.The procedure of optimizing short-circuit current limitation schemes in multi-infeed DC systems is presented as follows.Firstly,using a branch screening strategy to reduce the dimensions of the decision variables.Then,the nondominant sorting genetic algorithm Ⅱ is used to find the Pareto optimal solutions.Simulation results of actual power grid planning show that the model proposed has good applicability.关键词
