Multi-objective Hierarchical Scheduling Method for Emergency Power Supply in Power Enterprises Based on Differential Evolution Algorithm and Crossover Operator
In order to achieve efficient emergency repair of power system faults and reduce fault risks,a multi-objective hierar-chical scheduling method for emergency supplies in power enterprises based on differential evolution algorithm and crossover operator is proposed.This method combined the global scheduling needs of power enterprises to determine the multi-objective upper-level and lower-level scheduling objective functions for emergency supplies in power enterprises,while designing corre-sponding constraint conditions.We used differential evolution algorithm to solve the dual layer scheduling objective function.To ensure the diversity of solutions and algorithm convergence,we introduced evolutionary process information optimization algo-rithm to optimize the mutation probability of the mutation operator,thereby ensuring the effectiveness of solving the objective function.The test results show that the reverse generation distance and dispersion were below 0.034 and 0.28,respectively.Plan emergency material allocation paths based on the location of emergency material supply points and the fairness of emergen-cy material dispatch and satisfaction with resource coverage were both above 0.92.After scheduling,the risk consolidation function results of the power system were all below 0.14.
