基于源-荷运行模式划分的微电网经济运行随机优化方法
A stochastic optimization method for economic microgrid operation based on"source-load operation"mode classification
摘要
Abstract
The volatility of renewable energy output and the randomness of user-side electricity consumption behav-ior have led to increasing source-load uncertainties,posing significant operational risks to microgrids.To address this issue,an economic operation decision-making method for microgrids based on source-load operation mode clas-sification is proposed to achieve economic operation under uncertain conditions.First,a multivariate time series rep-resentation based on information granules is used,and the traditional affinity propagation(AP)is improved with spatial weighted matrix distance(SWMD).A multivariate time series clustering algorithm is applied to quantify cor-relations between variable dimensions,enabling the classification of microgrid operation modes.Second,a source-load probabilistic forecasting model for the target day is established using similar-day data under the same operation mode,and typical source-load forecasting scenarios are obtained through scenario generation and reduction.Fi-nally,the adaptive weighted particle swarm optimization(AW-PSO)is employed to solve the stochastic optimiza-tion model for microgrid operations.Case study results show that the proposed method effectively handles source-load uncertainties while reducing operational costs.关键词
