Access Mode Of Regional Generalized Demand Side Resource Under The Background Of Energy Interconnection

With the development of smart power distribution technology,big data and cloud computing technology,both sides of energy supply and demand will be more open and interactive more frequently.Under the background of the interconnection among power grid,natural gas network and fuel supply network,the behavior of demand side resources to participate in the power load response will become more complex.Especially,in the receiving side,there will be a large range of demand side resources with power attributes,including distributed power,smart controllable load resources,various types of energy storage equipment and electric vehicles based V2G.The large-scale access of these flexible demand side resources will have a certain impact on the safe and stable operation of the grid.Analyzing the characteristics of various types of generalized demand side resources and reasonably controlling all kinds of generalized demand side resources will break the one-way flow situation of power distribution from the distribution network to the user side so that the "network-load" has the dual interactive characteristics based on response and substantive electrical energy exchange.These typical generalized demand side resources will bring new challenges to the smooth operation of power grid,and at the same time,it will bring new opportunities to China’s DSM.Combined with the development trend of the future energy interconnection,this paper first sorts out the typical demand side resources in the future.Based on actual data,this paper studies the composition and classification of generalized demand side resources from different angles,and analyzes the development status of three kinds of generalized load resources,such as distributed power supply,electric vehicle and energy storage.Next,combined with the collected data,the paper uses Monte Carlo simulation(@risk)and probability analysis method to study the self supply and demand characteristics of all kinds of generalized demand side resources,and establishes the corresponding energy supply and demand model.Then,according to the demand and supply characteristics of all kinds of generalized demand side resources,the paper construct a decentralized and cluster access mode for typical generalized demand side resources in energy interconnection system,in which the centralized access mode takes the open market operation mechanism and the background of energy interconnection into account.Finally,the simulation analysis of the proposed access model is carried out.In the simulation,this paper analyzes the fluctuation of grid load after the access of typical generalized demand side resources considering the factors such as real time price and comprehensive energy price elasticity in the model of peak shaving and valley filling benefit based on Vensim.Through the analysis,this paper draws the future supply and demand characteristics of typical generalized demand side resources.The access mode of the typical demand side resource in energy interconnection system can reflect the flexible coupling between demand side resources and power grid in the open and interconnected energy consumption environment.And the access mode provides a guiding significance for the wide access of the typical demand side resources in the future.
