Research On Modeling And Method Of Electricity-heat Integrated Demand Response Based On Double Auction Retail Energy Market

With the rapid development of high-efficiency and low-carbon energy supply technologies,such as combined heat and power(CHP),heat pump(HP)and so on,the coupling interaction between different energy systems is becoming closer.In this context,the concept of regional integrated electricity-heat energy system came into being.However,with the increase of renewable energy penetration,the matching between renewable energy and energy coupling equipment has become one of the bottlenecks restricting the development of integrated energy system and renewable energy technology.In order to promote the absorption of renewable energy and improve the energy efficiency of electricity-heat integrated energy system,integrated demand response(IDR)has become the focus of attention of scholars at home and abroad.At present,the research on integrated demand response is still in its infancy at home and abroad.There are many research points that can be further explored,such as the modeling of integrated demand response resources,the design of multi-energy market framework,and the formulation of integrated demand response strategies.Therefore,based on the above background,this paper studies the modeling and method of electricity-heat integrated demand response based on the retail bilateral bidding energy market.The main work is as follows:(1)Considering the electro-thermal coupling relationship of regional electricityheat integrated energy system,the regional distribution network and heating network models are constructed,and two kinds of distributed energy station models are proposed.Considering the controllable resources at the demand side,the models of electric water heater and space heating load are established to provide a model basis for demand response.(2)The electricity-heat coordinated market models considering the net revenue of integrated energy service providers and the social surplus of both suppliers and consumers are proposed respectively.The bidding strategy of electricity/heat comtumers participating in the market is constructed considering the characteristics of energy consumption of users.And then the electricity-heat coordinated market model based on the net revenue of integrated energy service providers and the surplus of both suppliers and consumers is established respectively.(3)An integrated demand response control architecture for electric/heat load is proposed.A temperature-based control strategy with deadband and a zero deadband control strategy based on temperature setppoint are proposed for electric load.The heat power regulation based control strategy is proposed for heat load.
