Research On Energy Management Strategy Of Micro-Grid Based On MAS

In recent years,with the rapid development of renewable energy,distributed power supply it has received extensive attention and application.However,due to the distributed power supply is intermittent and volatility,large-scale grid will bring energy management complexity and operation instability etc.In order to give full play to the advantages of distributed power supply,puts forward the concept of micro power grid.Micro power grid is an independent control system,can run for interconnection,can also be independently to the local load power supply.But because of the distributed power easily affected by natural conditions,so the adjustment of the energy storage unit for the stable operation of the micro grid is necessary.This article in view of the micro grid energy management issues,put forward a kind of based on MAS(Multi Agent System)micro grid energy management strategy.In this paper,the main research contents are as follows:First,the paper introduces the research background and significance,the current micro grid research at home and abroad and the research status of micro grid energy management system based on MAS.Paper expounds on the multi-agent system,this paper introduces the basic structure of multi-agent,analyses the advantage of multi-agent in micro grid application,this paper introduces the micro grid structure of three kinds of energy management,elaborated in this paper,the micro grid unit in the composition and functions of each Agent unit,is proposed in this paper,the micro grid energy management strategy based on MAS.Secondly,a mathematic model of the micro grid units,and gives optimization of genetic algorithm based on improved particle swarm-results.On each unit in the micro grid model,the paper puts forward a single micro grid parallel operation of the real time control strategy,for the regulation of resectable load cell,energy storage unit and the unit interaction of power distribution network is optimized to get a single micro grid economic and stable operation of the optimal solution.Compared with genetic algorithm and improved particle swarm-the result of the genetic algorithm,the simulation in MATLAB,and proves that the improved particle swarm-genetic algorithm can get a single grid is the optimal solution of the stable economic growth.Again,the establishment of containing multiple micro power grid game model,and game algorithm based on benefit compromise is given.In this paper,the multiple micro grid power exchange between them,according to the benefit of compromise algorithm game recognised by all the micro grid power trading scheme,both the individual interests of each micro grid,avoid sacrifice the interests of the individual micro grid,not in the interests of the whole micro grid system is more as the goal,Narrowed its micro power grid operation cost or increase their return on micro grid.And simulation in MATLAB,we get the single micro power grid has been further economic and stable operation of the optimal solution,and each information interaction between the micro grid without a central management unit,realized the distributed energy management.Finally,the JADE platform,this paper introduces the functions and characteristics of the platform,based on multi-agent system structure of JADE,this paper expounds the communication mechanism between multiple Agent,this paper introduces the communication process,set up will be handled in the micro grid unit within each Agent on the JADE platform building and simulation,Got the Agent unit of information interaction process,and analyzes the micro grid coordinate the process of energy,to verify the feasibility of micro grid energy management based on MAS.
