Study On Electricity Power Market Under The Energy Internet Based On Nash Equilibrium

With the depletion of fossil fuels and the increase in environmental pollution problems,concerns about energy issues is increasing,then "Energy Internet" came into being.Energy internet build a smart system which take electricity power system as the core,with all kinds of renewable clean energy combined and the transport system coordinated.Energy internet bring ideas into energy systems which come from the internet:open,interconnected,equality,share,the ideas affect the electricity market as well.Compared to the electricity market in the traditional power system,the electricity market under the energy internet is more open,more complex,and more competitive.With the complexity of the economic behavior in the electricity market,the advanced of the research methods in the electricity market is essential.This paper Summed up the discussion of the energy internet and constructed a basic framework of it.Summed up the characteristics of the energy internet and the difference among the other smart systems.According to the development trend of the energy internet,constructed a structure pattern of the electricity market under the energy internet,and all part of it was analyzed.Based on the Game theory,constructed a model of tripartite static non-cooperative game model which contains State Grid Corporation,new power entities and users,explained the general form of game equilibrium solution.Applied the particle swarm algorithm to solve the Nash equilibrium solution.According to the programming results,analyzed the laws and problems of power distribution,electricity price and equilibrium influencing factors in electricity market.This paper based on the case analysis demonstrated the applicability of the research results.Based on the conclusion of this research,listed the problems worthy of further study and the suggestions of analysis.
