Large-scale Direct Purchase Electricity Trading Mode Under The Reform Of Power System

The direct-purchasing electricity trading mode of large users is one of the main manifestations of the power system reform.The Party Central Committee and the State Council promulgated the "Several Opinions on Further Deepening the Reform of the Power System" in 2015,and proposed that the existing power system should be fully reformed,especially It is necessary to focus on improving the trading mechanism of the electricity market and continuously promote the reform of the power trading system,which has also set off a new round of reforms in the Chinese electricity market.After the promulgation of "Several Opinions on Further Deepening the Reform of the Power System",the pilot work of large-scale direct purchase of electricity in China officially ended.The large-scale direct-purchasing electricity trading mode began to enter the development period,and the direct purchase of electricity by large users under the power system reform The trading model is studied,which is also the need for China's electricity market to be in line with the international electricity market system.By exploring the direct-purchasing electricity trading mode of large-scale users under the reform of power system,it is beneficial to introduce the competition mechanism to the power-selling side,to establish and improve the current power market system,and to facilitate the realization of power-using enterprises,transmission enterprises,and power generation enterprises.Win-win,it is also conducive to the mining of the potential of the power market,which is extremely important for the sustainable development of China's power industry.The full text is divided into six chapters.The first part is the question,which mainly analyzes the research background and significance,deeply discusses the research status at home and abroad,and proposes the research method.The second part is the theoretical basis and reform process of the electricity market.The third part is the development part of directpurchase of electricity by large users.The fourth part is the priority bidding method for direct-purchasing electricity transactions of large users under the reform of electric power system.Firstly,the priority strategy of direct purchase of large-sized users is designed.Secondly,the model of determining the priority of large users is established.Again,the priority of large users is analyzed.Level determination method.The fifth part is the electricity forecasting strategy for large-user direct purchase electricity transactions under the reform of electric power system.In order to avoid the situation of “peak-to-peak reverse”,the power supply benchmark is introduced,and the large-user electricity forecasting model is established as the starting point,and then the analysis is large.The user points the equilibrium point and contradiction point of the power;and based on the gray model to predict the power,the simulation results show that after applying this strategy,both the large user's electricity purchase cost and the large user's power consumption are obvious.Reduced ground.The sixth part is the design of the transaction mode of multiple large users and multiple power generation enterprises under the reform of electric power system,which can make the final transaction price of both parties accurately determine.The simulation results of the example show that the Bayesian-mixing strategy has strong Feasible and more advanced,it can enable large users to obtain more expected benefits and better strategies in the process of purchasing electricity transactions,and can improve the negotiation ability and belief renewal ability according to the other party's beliefs,so as to better carry out with the opponents.Negotiation,the final realization of the transaction link is the most succinct,and the negotiation process time is minimized.
