Analysis Of The Trading Strategy In The Integrated Energy Market Of The Energy Internet

With the rapid development of the Internet information technology,building an energy Internet that deeply integrates renewable energy and Internet information technology has gradually become an important method to solve energy problems.On the physical level,the development of integrated energy utilization technologies,such as CHPP and P2 G,provides the possibility for the construction of the energy Internet.On the application level,marketization is the future of the energy Internet,but the theory of the integrated energy market transaction of the energy Internet is not perfect at present,which needs to be further studied.In this paper,the trading strategy in the integrated energy market of the energy Internet is studied.Based on the optimization of participants’ behaviors and the network operation,the equilibrium state of the market in the game is solved and the trading strategies in the market of the energy Internet are analyzed.Firstly,the operation mechanism of the energy Internet and the concept of the integrated energy entity are introduced.Combined with the general model of the energy Internet,the internal model of the integrated energy entity is established.Under the premise of satisfying the terminal energy supply,the optimal energy purchase strategy of the integrated energy entity is proposed.Using the time and space flexibility of utilization brought by the energy conversion,the purchase amount of all kinds of energy and the working state of the conversion equipment are optimized to achieve the goal of the highest revenue.Meanwhile,the influence of factors such as prices of energy on the energy purchase strategy is analyzed.Secondly,the mathematical models of the energy networks of electricity,gas and heat are established respectively,which constituted the balance constraint of the energy Internet network.The energy Internet optimization models under the fixed operation mode and collaborative operation mode are proposed.Under the fixed operation mode,the energy supply from the integrated energy entity to the end users and the energy supply from the energy producer to the load are respectively optimized,while the integrated energy entity participates in the operation with its own economic optimal energy purchase strategy as the fixed load.Under the cooperative operation mode,the integrated energy entity participates in optimization as variable loads under the constraint of energy supply to end users.The system operator maximizes social welfare through the transformation of different types of energy loads on the energy InternetFinally,the trading strategy and equilibrium state of the integrated energy market by integrating the optimal purchasing strategy of the integrated energy entity and the economic operation of the network are analyzed.Under the environment of the integrated energy market,the impact of interconnection on the cross-elasticity of energy commodities is described,and the price adjustment strategy of energy suppliers is established.Based on the game theory,the scenario of the complete information dynamic cooperative game of the integrated energy market is analyzed.Under the dynamic price,the optimal paths of the trading strategies of participants are obtained through repeated game process.The game process and the change path of trading strategy in the integrated energy market of the energy Internet are analyzed through an example in detail.
