Research On Pricing Strategies Of Energy Service Providers Based On Game Theory

With the rapid development of the energy internet and the in-depth reform of the liberalized energy market,the construction of an internationally leading energy internet enterprise with Chinese characteristics has been accelerated,and energy service providers have emerged.Energy service providers link up with energy companies and directly communicate with energy users.As a core member of the energy market,maintaining real-time energy balance,coordinating multi-party income balance,and avoiding fluctuations in energy wholesale prices and spot prices are of great significance.In this context,this article proposes a comprehensive energy pricing mechanism that includes energy companies,energy service providers and users in the energy supply chain.The main contents are as follows:First,it introduces the research status of integrated energy system,integrated energy market and its pricing strategy.A comprehensive energy market framework including energy service providers has been established,and the working principles and mathematical models of the internal coupling components of energy service providers have been studied.In addition,the basic concepts,basic elements and basic classifications of game theory are explained,and related analysis methods of non-cooperative games,Bayes games and Stackelberg games are introduced.Second,in order to maximize the benefits of energy service providers,a non-cooperative game model between energy service providers based on retail price elasticity has been established.Coordinating the revenue of the energy supply chain through the revenue sharing contract mechanism.At the same time,the energy service provider will select the contract terms provided by the energy company and set the retail price of energy to maximize its own revenue.The Nikaido-Isoda function is used to transform the non-cooperative game model between energy service providers into optimal problem solving,which proves the existence and uniqueness of Nash equilibrium.The simulation proves that the proposed model and method can realize the multi-party income balance under the guidance of energy service providers in the integrated energy system,and analyzes the impact of different income sharing factors on the income of energy companies,energy service providers and energy supply chains.Finally,based on Bayesian game theory and Stackelberg game theory,the pricing problem of energy service providers and energy users in the energy market is studied.In order to protect the privacy of energy use information between users and maximize the energy consumption income of users,a horizontal game model between energy users based on Bayesian game is established;in order to optimize the income of energy service providers,the establishment Based on the vertical game model of energy service providers and users based on the Stackelberg game,the energy service provider is the leader of the game,and the user is the follower of the game.In addition,a price adjustment mechanism based on the balance of energy supply and demand is designed to achieve the balance of supply and demand in the energy market,and a distributed iterative algorithm is used to solve the system pricing model,thereby obtaining the optimal retail price and adjusted price of energy.
