Optimal Dispatch Of Regional Integrated Energy System Considering Demand Side Response And Renewable Energy Consumption

With the rapid development of the society,the demand for energy is increasing day by day.Regional Integrated Energy Systems play an important role in the on-site integration of renewable energy and the cascade utilization of energy.The regional integrated energy system includes many kinds of energy conversion equipment,which can meet the energy demand of users by coordinating the operation of the equipment.However,there exists the problem of benefit distribution among different subjects in the system,and it is the key point to realize the full absorption of renewable energy to arouse the enthusiasm of demand side.The main objective of this paper is to find the optimal solution to the above problems by using the idea of game theory,in order to improve the efficient energy use and safeguard the self-interest of the subjects.This paper first introduces the severe situation of energy problem in our country and the effective solution of regional integrated energy system to the problem,including modeling and analysis methods,optimization scheduling strategy,demand response technology and so on.Secondly,the paper models the equipment,energy coupling part and renewable energy output in the regional integrated energy system,and then introduces the three stakeholders in the regional integrated energy system,they are energy suppliers,integrated energy users and integrated energy operators respectively,and the mathematical models of the three stakeholders are established,Through the analysis of the interaction process between the stakeholders in the model and the multi-energy flow process of the system,the preliminary simulation results are obtained through the example,and the simulation results are analyzed,demand-side response has great potential for the integration of renewable energy in regional integrated energy systems,but taking into account the conflict of interest between the demand side and the energy supply side,as well as the high sensitivity of users to electricity prices,then a demand response model based on dynamic non-cooperative game is adopted to verify the uniqueness of Nash equilibrium and realize the coordinated decision-making of demand response and energy utilization.On this basis,the concept and principle of incentive demand response and cooperative game are introduced,and a new optimal scheduling model is established to prove the existence of Nash equilibrium solution.The simulation results show that the model can not only fully achieve renewable energy absorption and reduce carbon emissions,but also can reasonably distribute the benefits.Finally,the results are analyzed and summarized,and a series of feasible strategies and models are proposed for the optimal scheduling and management of regional integrated energy systems,and from the theory and practice of two aspects of its in-depth study and research.On this basis,it points out the future research direction and expects to make greater contribution to sustainable development.
