计及柔性负荷资源的分布式智能电网安全域建模
Modeling of distributed smart grid security region considering flexible load resources
摘要
Abstract
With the increasing penetration of renewable energy resources(RES)and flexible loads(FL),their potential in enhancing the security regulation of MV/LV distribution systems has become increasingly evident.Considering the impacts of extreme renewable energy output conditions and flexible load behaviors,this paper proposes a distributed smart grid security region(DSG-SR)model that incorporates RES and FL.First,the operational characteristics of RES and FL are analyzed,and their corresponding mathematical equations are established,followed by discussions on constraints related to normal operation and N-1 security.Next,treating the operational modes of RES and FL as state variables,a DSG-SR model is established considering the extreme output scenarios of RESs and the FL response cost constraints.Finally,the application of the DSG-SR model is illustrated through two-dimensional cross-sectional plots,revealing the mechanism by which RES and FL influence the DSG-SR.The proposed model can serve as a practical tool for security analysis in distributed smart grids,providing key technical support for secure and stable operation and for the design of market mechanisms in distribution systems with high shares of RES and FL.关键词
