Utilization of Public Building Flexibility for Distribution Network Congestion Management and Method for Distributed Market Clearing
摘要
Abstract
To address the issues of line congestion and voltage congestion in distribution network caused by the wide-spread integration of distributed energy resources,a method for utilizing the flexibility of public buildings and a clear-ing method for the distribution-level flexibility market(DFM)in distribution network congestion management are pro-posed,which take advantage of the flexible regulation potential of thermal inertia of building energy use.First,a three-layer architecture of DFM involving a distribution system operator(DSO),flexibility aggregators and building users is constructed.Based on the day-ahead energy management scheme for building clusters and microgrid systems,the line overload and node voltage drop are identified through power flow analysis,and the flexibility demand is obtained.Sec-ond,the users'flexibility resources are aggregated to construct a DFM clearing model that balances the interests of both the DSO and the flexibility aggregators,and a distributed clearing method based on the alternating direction meth-od of multipliers(ADMM)is adopted,where only the optimization variables of the coupled boundary are exchanged to protect the user privacy.The flexibility prices and power can be synchronously optimized,so as to formulate a reason-able trading plan.The result of a case study demonstrates that the proposed method can effectively alleviate congestion in distribution network and bring flexibility service benefits to aggregators and users.关键词
