Optimal Allocation of ESS in Distribution Network Containing DG Base on Timing-Voltage-Sensitivity Analysis
摘要
Abstract
Distribution power system voltage violation problem caused by distributed generation (DG) integration is becoming more and more significant.As have a flexible power regulation capability,energy storage system (ESS) is an effective way to support distribution network voltage control.A calculation method for ESS location based on timing sensitivity has been presented,in order to improve the distribution system voltage control ability.Firstly,the node voltage violation quantity was adopted as the weighting factor to improve the sensitivity index.Secondly,different node voltage adjustment direction was considered.Third,based on time series model,sequential sensitivity index was proposed.Fourth,and effect of different distribution network operation modes was accounted,increases the adaption of ESS allocation scheme.Finally,genetic algorithm was used to optimize the capacity of ESS.The modified IEEE33 bus system and a actual distribution system are simulated and result shows that:the method presented in this paper considering the variety characteristics of active distribution network,effectively improve the ESS voltage support ability of active distribution network,taking into account the different node voltage adjust demands.Moreover,the observed allocation scheme and can meet the requirements of different distribution network operation modes.关键词
