基于"源-荷"不确定性的配电网用电负荷分布式协同控制
Distributed Collaborative Control of Electricity Load in Distribution Networks Based on Source-Load Uncertainty
摘要
Abstract
With the continuous increase in the scale of distribution network construction and operation,a large number of electricity load control problems have emerged,especially the weakening of sample time series characteristics in electricity load data analysis,resulting in incomplete acquisition of local load characteristics,making it impossible for the distribution network electricity load prediction system to maintain the balance of energy in the power grid.In the past,the impact of"source-load"uncertainty was also rarely considered in the distribution network electricity load processing and distribution,which can easily lead to low probability of electricity load classification recognition,significant errors in electricity load prediction,and long-term problems such as high generation costs and insufficient distribution balance.In response to the above situation,the uncertainty of"source"and"load"was conducted research through probability distribution functions.A multi-objective function composed of two probability distribution functions was set as the constraint conditions for the coordinated output balance.The improved cluster eddy current search algorithm was used to solve the problem,and a coordinated control scheme for electricity load was obtained.The test results show that at 17:00,the power of photovoltaic device 1 is 1 050 kW,at 11:00,the power of photovoltaic device 2 is 980 kW,based on the source-load uncertainty root-mean-square error of less than 0.7%.The cost of the scheme based on"source-load"uncertainty is 453 200 yuan,and the balance degree is 0.94.The collaborative control method based on"source-load"uncertainty has a higher balance than the collaborative control method without"source-load"uncertainty,and the collaborative control technology is more reasonable.关键词
