Research On Bidding Strategy Of Power Electricity Retailers Based On Stackelberg Game

In March 2015,the release of "No.9 document of power reform" opened the prelude of a new round of power system reform.More and more provinces gradually opened up the power sale side trading market and actively participated in the reform process;As an important participant in the electricity market,how to make profits in the market needs further discussion.First of all,we need to fully understand the situation of the electricity market,and at the same time,we need to innovate the profit model to improve the profitability and viability.The reform of the electricity selling side has been gradually promoted,showing three major development trends:First ofall,the electricity retailers of power generation enterprises have strong comprehensive competitiveness in the electricity selling market,and become the main body of electricity selling;second,at themoment,China’s electricity retailers are still in the development stage of highly relying on "price differences",and most small and medium-sized electricity retailers in low price differences areas are under great operating pressure;thethird oneis electricity retailers with various core resources have more advantages,such as power generation companies(with business chain advantages),power construction power sales companies(with channel and cost advantages),and new electricity retailers(with strong business model innovation ability,which can use network analysis to find profit points of value-added business).At present,theelectricity retailers are subject to price reduction by power generation companies in the market,the increase of profits to users,the greater industry pressure and the increasing pressure of sustainable development.In order to survive and develop in the market,the electricity retailers need to formulate effective bidding strategies.According to the positioning of power sales companies in the reform,they need to provide personalized and diverse value-added services for users,including energy-saving related services,personalized electricity service customization,etc.This thesis is mainly based on electricity retailers as the main research object,and studies the two game situations that electricity retailers face in power transactions.One situation is facing a competitor retailer,and the other is facing power users;The article is based on the Stackelberg game model for bidding strategy game research.Firstly,it studies the competitive strategy game for electricity prices between electricity retailers of different sizes and types.Through the establishment of their respective game models,they are then verified by simulation.The effectiveness of the model and the impact of its related parameters on the bidding strategy;secondly,it studies the electricity price game between the electricity retailers and the electricity users,analyzes the factors that affect the choice made by the electricity user,and establishes the electricity retailerand the electricity user respectively.Based on the game model under the influence of quality level,the electricity retailer’s purchase and sales strategy is analyzed.Because electricity retailers face some potential risks and other factors,they need to make accurate judgments on prices,electricity,etc.during the game between the two parties,and at the same time,they also propose a solution to get an equilibrium solution,thereby achieving a game equilibrium.Based on the aboveanalysis,the competitive game model of electricity retailers shows the dynamic real-time pricing schemes of electricity retailers of different sizes when trading in the electricity market.The results can reflect the overall change trend of electricity prices at the optimal equilibrium price,and consider the actual impact.Factors in price changes,establish a game model to simulate real game scenarios,and finally get the result that the two companies will eventually reach equilibrium in terms of prices,and analyze the simulation results to provide relevant basis for the formulation of strategies when electricityretailers compete in actual power transactions.Show the results of the group game of electricityretailers.The research on electricity sales strategy of electricityretailers puts forward a game model based on Stackelberg game and power quality pricing as the main influencing factor.During the analysis process,multiple electricityretailers play games with multiple users,and the reference price and rationality of electricity users are introduced.Based on the selected model,the optimization model of user income and the income of electricityretailers are established respectively,and the optimal electricity price is found through the Stackelberg game solving model.The calculation example analysis shows that the power pricing method based on Stackelberg game can determine the reasonable selling price,can meet the power quality and income requirements of users,and ensure the profitability of the electricityretailers.In general,this thesis combines the game theory and modeling research methods to study the influencing factors and price change trend of electricity retailers,and puts forward relevant suggestions for the formulation of bidding strategies of electricity retailers.The research results have certain theoretical value and practical significance for the sustainable operation and profitability of electricityretailers in the new environment of power market operation.
