基于随机森林算法的综合能源配电网电能质量评估方法与网架优化模型
Power quality evaluation method and grid optimization model of integrated energy distribution network based on stochastic forest algorithm
摘要
Abstract
Aiming at the power quality problems of integrated energy distribution network,the grid optimization measures are adopted for optimization.Firstly,considering the four indices of voltage deviation,harmonic voltage,voltage fluctuation and three-phase imbalance,the analytic hierarchy process(AHP)is used to establish the power quality evaluation system of integrated energy distribution network,in which the subjective weight of each index of the evaluation system is determined based on fuzzy analytic hierarchy process.Then,taking the comprehensive energy distribution network optimization scheme as the control variable,considering the complementary operation of various energy forms in the system,taking the maximization of distribution network power quality evaluation index as the objec-tive function,and taking into account the necessary constraints such as distribution network topology constraints,node voltage constraints and network radial constraints,the distribution network reconfiguration optimization model is estab-lished.The operation principle of the stochastic forest algorithm is analyzed,and the model solution process is designed based on the stochastic forest algorithm.The simulation algorithm analysis shows that the established model can improve the power quality of distribution network,and verifies the correctness and effectiveness of the model.关键词
