Research On Trusted Transaction Of Microgrid Energy Based On Blockchain

With the rapid development of microgrid in the power industry,the micropower trading begins to market,which has important theoretical research and social value.The existing blockchain based microgrid energy trusted transaction has the following problems.The first is that the existing microgrid energy trusted trading model based on blockchain is mostly aimed at a specific level,ignoring the relationship and interaction between the whole model data,which leads to the lack of flexibility of the model.Moreover,the existing microgrid energy trusted trading model based on blockchain uses single chain storage mode,which leads to a large number of repeated storage of all the data generated by the model,and there is a waste of storage resources.The second problem is that the existing blockchain based microgrid energy trusted trading model focuses on energy management and scheduling control between microgrids,and does not fully consider the bidding problems existing in the market-oriented trading of microgrid energy,which leads to the difficulty of trading strategies to adapt to new market changes.In view of the problems of lack of flexibility and waste of resources in the power trusted trading model of microgrid based on blockchain in problem 1,a power trusted trading model of microgrid with doublechain storage structure is proposed.The model is divided into physical layer,data information layer and network finance layer,and multi-agent is set up in each layer,which can improve the flexibility of the model.The storage mode of the model is physical blockchain and transaction blockchain.Each chain has different functions and different data types.It can effectively solve the problem of storage resource waste in microgrid trusted trading model based on blockchain.Aiming at the bidding problem of microgrid energy trusted trading model based on blockchain in problem 2,this paper studies the power trusted trading strategy of microgrid with incomplete information game and the power trusted trading strategy of microgrid with continuous bidirectional auction mechanism.The former takes into account the different types of distributed power supply in microgrid,and analyzes the power trading strategy of microgrid by using incomplete information game theory.Under the condition of satisfying the balance of supply and demand,the Lagrange multiplier method is used to optimize the profits of both parties to the transaction,so as to optimize the trusted trading of microgrid electric energy.Through the simulation of experimental data,the results show that under the trading strategy of incomplete information game,the profits of both parties are balanced in the electric energy transaction,which ensures the interests of both parties.Considering the fluctuation of electric energy price in microgrid electric energy trading market,the latter uses continuous two-way auction mechanism to analyze the electric energy trading strategy of microgrid.In the electric energy transaction of microgrid,the adaptive learning theory is used to adjust the quotation of both parties,so that both parties can make reasonable quotation according to the market environment.Through the simulation of experimental data,the results show that under the trading strategy of continuous two-way auction mechanism,the two parties can dynamically adjust the quotation according to the market transaction information,which has a good adaptability to the market-oriented trading of microgrid electric energy.In this paper,the reliability trading problem of microgrid based on blockchain is studied.This paper puts forward a reliable trading model of microgrid based on blockchain,which solves the problems of lack of flexibility and waste of resources,and ensures the credibility of electric energy trading.The experimental results show that compared with the existing trading strategies,the trading strategy of this paper can better adapt to the market-oriented environment of microgrid energy trading.This provides a certain reference value for the construction of microgrid energy trading platform.
