Research On Energy Management Method Of Smart Community Based On Game Theory

In the 21st century,the society has a rapid development,the demand and usage of traditional energy and green energy in human society are increasing.In this study,the research related is done for the purpose of the way to meet the power consumption command of the users in the community.Besides,the efficiency of power consumption need to be improved,too.And the users in the community ought to enhance the frequency of the distributed energy,increasing the overall interest of the community.As a kind of cluster form of buildings,the energy consumption of community is the focus of people's research.On the basis of smart community,this paper studies the mode of energy trading,and discusses the object and mode of energy management.First of all,this paper explores the smart community energy trading mode,introduces the basic architecture of the community microgrid,constructs the energy trading mode between the community and the microgrid,and analyzes the current trading market.Under this trading mode,how to reasonably optimize the scheduling of their own energy,make the energy distribution of the microgrid more reasonable,and reduce the cost of community users.The simulation results show that different types of building communities have different effects on users' power use.Secondly,aiming at the problem of community energy generation is not timely,a new community energy management model based on the master-slave game is proposed on the basis of the previous chapter: under the traditional community microgrid power supply mode,a community energy manager mode is proposed.Under the control and allocation of the community energy manager,the community users stagger the power consumption time of other users,the users save a lot of energy management steps.In addition,it help reduce the power cost as well as decrease the waste of the energy of microgrid.What's more,it maximize the interests of the users.At last,the superiority of the proposed model is verified.Then,according to the situation of excessive or insufficient renewable energy generation in the community,the excess community energy is added into the energy trading relationship between microgrid and users as distributed energy storage.From the perspective of interests,the community users sell the surplus energy through the third-party management,which optimizes their own energy structure on the one hand,and increases their income on the other hand.Based on the smart community with energy storage devices,this paper establishes a Stackelberg game model of smart community microgrid.It is proved that the game model has a unique equilibrium.The simulation shows that the model can help to improve the utilization rate of the distributed energy in community,which guarantees the consumption of the power energy for users as well as increase the economic benefit of the users in community.Besides,the model can alleviate the energy shortage problem of the microgrid.Finally,the superiority of the proposed method is verified.To sum up,this paper mainly studies the smart community oriented micro grid energy scheduling,micro grid energy trading and user demand response,mainly uses the knowledge of game theory to solve the community power generation is not timely,power generation peak is inconsistent with power consumption peak.At the same time,it also looks forward to the problems of residents' electricity habits in the future.
