Research On Competition Decision Of Power Quality Differentiation In Electricity Sale

In the market environment where the sales side is released,the electricity sales market will gradually form a “multi-buyer-multi-seller” pattern.The sales company and the user become equal market participants,and can choose the transaction object independently.The user's choice of choice will inevitably increase competition in the electricity sales market.In order to gain market share and win more economic benefits,electricity sellers are no longer simply trading with users,and will cater to users' needs or facilitate users' use in improving the quality of electric energy products,service levels and adding other value-added services.Based on the competition of power quality,this paper proposes a method based on master-slave game to differentiate the power quality of multi-sales power consumers.First,perform power quality differentiation analysis and grading evaluation.From the perspective of power quality compatibility of equipment groups,a power quality comprehensive evaluation index system based on equipment compatibility is constructed,and an indicator weight determination method considering power user loss is proposed.The extensional evaluation method is used to comprehensively quantify the grid power quality.Secondly,it studies the decision-making method of differentiated power quality power supply for a single power seller.The power quality pricing model is established on the basis of the theory of energy quality pricing.The income model of the main body of sales and the user profit function are established.The particle swarm optimization algorithm is used to optimize the solution,and the decision of the power quality difference of the single power sales subject is obtained.Finally,in the electricity market where there are multiple power-selling entities and multiple load clustering regions,the research on the differentiated power quality decision-making method of the market-selling multi-market subject is carried out.The power quality is used as the decision variable to construct the game model of the electricity seller,and the non-cooperative static game method is used to optimize the power quality level of the electricity supplier.The user game model is constructed by considering the user's power purchase cost and high-quality energy use cost.The optimization algorithm clarifies the power quality level of the user's purchased electricity and the transaction object.The idea and process of power quality competition for power sales competition decision based on master-slave game are given,and a case study is carried out.
