Research on Electricity Market Trading Mechanism Considering Peak‐to‐Valley Ratio and Multitime Coupling

Abstract

With the development of the economy and society, electricity demand is increasing. However, there are some problems on the power grid side, such as the excess capacity of power installed, abandoned power of renewable energy, low overall utilization rate, and high pressure of stable operation. The problem stems from the inconsistency between the peak of electricity production and consumption and the lack of obvious power price signals. In this article, the market development objectives are combined with the time-divided transaction, and two objectives of market development are proposed: (1) Reduce the peak-valley difference of power supply and demand; (2) Expand the peak-valley price difference in the market. Combined with the physical properties of the power market, a multiperiod coupling trading mechanism is designed. The results show that the speculative and profit-seeking behavior of power producers will be stopped under the proposed trading mode, the potential of users for peak-valley filling will be effectively developed, the peak-valley gap of the power system can be controlled within a reasonable range, and the peak-valley gap of power trading can be further amplified.

Research on the Trading Mechanism and Trading Strategy of Electric Power Market under the Background of new Electric Power System

“…The node electricity price is taken as the short-term marginal cost pricing method reflecting the power value of different moments and different positions as the transaction mechanism to construct the power market under the background of the new power system. [2] As can be seen from Figure 1, the transaction needs to declare its segmented quotation curves through the market participants before starting, and the market pre-clearing results should be calculated with the goal of the minimum power purchase cost. If no clean energy power is generated in the clearing result, the result is taken as the final clearing result; but if the new energy is abandoned in the result, the compensation generator system is started.…”

“…In order to ensure the effectiveness of the trading mechanism of power spot market and deal with the problems of distributed energy power consumption and the construction of power spot market, a large number of scholars at home and abroad have studied the consumption mechanism of distributed electricity and power market. At present, Cui D and some foreign scholars have made some discussions on the current foreign market trading mode of new energy, and made relevant research on the price system to promote the consumption of clean energy under the background of the current competitive electricity market., They have introduced MTDG technology based on blockchain technology, and constructed the corresponding trading mechanism, settlement mechanism and reward and punishment mechanism..Literature [2] to literature [4] reflects the domestic scholars on the contract for difference and optimization strategies in the provincial power market, which provides effective reference for the design of new energy consumption mode and spot market mechanism under the background of the current new power system. Based on the current research background at home and abroad, combined with the current clean energy affordable given rules and electricity spot market trading operation mechanism, puts forward the optimization of clean energy given trading mechanism, with distributed electricity build compensation mechanism, on the premise of protecting the rights and interests of the market, improper planning of clean energy electricity quotation, in order to increase the cost of market trading mechanism to regulate the electricity spot market trading mechanism.…”
