Study On Partition Transmission Pricing Method Considering Blocking Risk And Power Market

In the process of power market reform in countries around the world^[1],the establishment of an independent transmission company is the only way to reform.The transmission network is open to the whole society's power grid users,and promotes free competition on the power generation side and the power sales side.Under the traditional power transmission management mode,the direct result of eliminating the transmission resistance plugging method is that the transaction cost of the transmission network is significantly increased,causing the participants of the transmission network to bear the economic loss.Therefore,it is of practical significance to study transmission pricing under the premise of considering the risk of congestion.Based on the research of power market and congestion management,this paper proposes a partition transmission pricing model that takes into account the transmission network congestion risk and power transaction contract priority.The article introduces the power market in the United States,Australia,the United Kingdom^[2]from a macro perspective,and introduces the general situation of its congestion management.The paper then expounds the composition of transmission cost and introduces and analyzes the distribution method of transmission cost.Finally,the Baiel line trend tracking method is used to calculate the fixed cost allocation factor of the line.The idea of transaction contract priority order and transmission network partitioning is also introduced into the transmission fee pricing,and the transmission pricing model considering congestion risk is summarized.The paper gives a specific theoretical model and practical application case for the partition transmission pricing considering the risk of congestion.The actual case combines the actual situation of the electricity market in the southern region of China,and introduces the power trading center into the trading organization of the transmission pricing method.Finally,based on the actual case data,it is concluded that the new method can eliminate the problem of the transmission plug.It can also be seen that in order to ensure the normal operation of the transmission network,under the goal of maximizing market efficiency,the power-related institutions need to be constrained and adjusted.This comprehensive transmission pricing method can reasonably guide users to use electricity,peak clipping,and eliminate the risk of blocking to improve the efficiency of terminal power consumption,and at the same time,it will not increase the user's electricity consumption.
