Research On Financial Transmission Right Mechanism And Its Application In China Power Market

The construction of electric power spot market is one of the important work contents of electric power market reform.The node electricity price mechanism is a price mechanism commonly used in the spot market,which can provide electricity price information in time-sharing locations,reflecting the value difference of electricity at different times and in different nodes.Under the node electricity price mechanism,grid power transmission capacity congestion will cause congestion fees between nodes,and congestion surplus will occur during market settlement.Corresponding congestion management mechanisms are needed to solve the congestion problem and the allocation of congestion surplus.For the smooth transition of the market reform and construction,the changes in the interests of relevant market entities before and after the reform are one of the key issues that must be paid attention to during the reform process.The financial transmission right mechanism is one of the effective means to solve the problem of congestion management under the node electricity price mechanism.It can separate the power transaction from the actual physical energy transmission,so that the use of the transmission right does not affect the actual dispatch of the power system,and effectively coordinate transmission and generation.To achieve efficient use of transmission capacity,rational use of transmission grid resources and maintain safe and stable operation of the system.In view of the problem of excessive changes in the interests of market subjects before and after the reform,the initial allocation of financial transmission rights can also be adjusted to achieve a steady progress in the reform.In order to solve the above-mentioned problems faced by China in the early stage of market reform,this paper studies the financial transmission right mechanism,combined with the current status of Chinese second round of power market reform,proposes a financial transmission right allocation mechanism that adapts to the current status of Chinese power market reform,to further Improve Chinese electricity market system.This article first sorts out the relevant theories of financial transmission rights,focusing on the analysis anddiscussion of the core issues of financial transmission rights;then,the spot market reforms have resulted in excessive changes in the interests of various market entities and there is no legal avoidance of the risk of blockage on the power generation side in the spot market And other issues,put forward solutions from the perspective of transmission rights,and established a financial transmission rights allocation model and solve it;established a mechanism evaluation scheme from both aspects of market efficiency and fairness goals,taking the standard deviation of the total social welfare and the change in market power generation interests as The evaluation index evaluates the financial transmission right allocation mechanism proposed in this paper;finally,the effectiveness of the mechanism is verified through the analysis of 14-node examples.Finally,the financial transmission right allocation mechanism proposed in this paper is applied to the Guangdong power market,and the application effect is verified through the IEEE-30 node example.
