Bidding System Research Based On Multi-Agent Micro-grid In JADE Platform

With the deepening reform of the power market,the monopoly of the power industry has begun to be broken,and the marketization of electricity will become a trend.The new power grid,the micro-grid,has been built and rapidly developed with its advantages of cleanliness,less pollution,low cost.Faced with the emergence of a large number of micro-grids,it is necessary to establish a micro-grid power market to solve the surplus power of the micro-grid.With the gradual maturity of micro-grid technology,the micro-grid will participate in the bidding of the power market in the future.Considering the inherent characteristics of the micro-grid,the traditional electricity market bidding mechanism is difficult to adapt to the new micro-grid power market.In this context,multi-agent systems can better adapt to the development needs of the micro-grid power market by virtue of their autonomy,interactivity,wide distribution,and mutual coordination.Based on the bidding demand of micro-grid and the related knowledge of multi-agent technology and game theory,this paper deeply studies the micro-grid bidding system and realizes the bidding of micro-grid in multi-agent system on JADE platform.Firstly,this paper makes a systematic and in-depth study on the multi-agent system,and carries out a series of analysis and interpretation of the agent prototype.Then introduced the basic concept of micro-grid and the organizational structure of multi-agent in micro-grid applications.Secondly,this paper proposes a multi-agent micro-grid bidding simulation system based on JADE.The agent technology is used to construct the distributed micro-grid bidding system architecture.Each agent in the system architecture is classified and deployed to elaborate its functional modules,and the interaction between information and communication mechanisms of multi-agent is established.The system has the characteristics of mutual coordination and mutual interaction.As a theoretical guide to the system,this paper introduces the game theory and the Gournot model under incomplete information as the basis for the application of theory.The trading algorithm and trading strategy are carefully designed,and the micro-grid bidding process is proposed to analyze and explain the operability of the corresponding algorithm in the Agent.Finally,the information interaction between multiple agents is implemented on the JADE platform.Taking micro-grid as the research object,the multi-agent quotation system of micro-grid was simulated by JADE platform and the feasibility of the method was verified.The system adopts the object-oriented language JAVA language to complete the corresponding game algorithm.The realization of this method helps to avoid the randomness of micro-grid bidding,and effectively improves the economic benefits of micro-grid power market transactions.
