In order to implement the requirements of the power system reform, to ensure the safety, stability and economic operation of the power system, and to promote the consumption of new energy, all provinces in China have built the peak-control auxiliary service market, and explore the establishment of a new mechanism for sharing and sharing of peak-control auxiliary services. Based on the operating rules of the peaking auxiliary service market in Xinjiang, Shanxi, Gansu, Fujian, Jiangsu, Jiangxi, Northeast, Anhui, Ningxia, Shanghai, Shandong and other places, the author compares and evaluates the key content of the market operating rules from four aspects: market members and their responsibilities, deep peaking transaction details, emergency start-stop peaking transaction details, and measurement and settlement, and also finds a direction for the provinces to revise or adjust the rules of peaking auxiliary services in the future for the reference of power grid dispatching, power plant operations and other departments, in order to improve the understanding of relevant personnel of the peaking auxiliary service market.

The use of new energy to generate electricity in the power system and the large-scale increase of new energy grid connection has led to increasingly insufficient power system regulation, in order to solve this problem, the peak shaving auxiliary service market came into being.This article comprehensively analyzes the factors those affect the market clearing price of power peak shaving auxiliary services: The macro factors include energy economic policies (renewable energy and electric energy substitution), technological innovation, market operation rules, etc., and the micro factors include the quotation and demand of thermal power plants and wind power generation.The power peak shaving auxiliary service market is an important part of the power market. Its appearance makes the grid operation safer and more reliable, and the reasonable fluctuation of clearing prices and total market costs reflects the market’s sensitivity to peak shaving resource demand.This paper uses the BP neural network model to select 31 consecutive days of peak shaving auxiliary service clearing price data in North China for prediction.

This article mainly analyze the shortcomings of the inherent peak shaving auxiliary service mechanism in the high-proportion of new energy access scenarios in Northeast China, which restricts the enthusiasm of thermal power units to participate in peak shaving. For this reason, a dynamic peak shaving compensation benchmark is proposed which follows load changes. At the same time, in order to standardize market behavior and facilitate market supervision, a guiding formula is proposed for quotation of thermal power units. Based on the above, a dynamic auxiliary service market mechanism is established which used actual operating data of Liaoning province power grid as a calculation example to verify that the mechanism can effectively improve the enthusiasm of thermal power units to participate in peak shaving, which is conducive to market operation and supervision as well.

Trading Mechanism

In recent years, in order to promote the consumption of new energy, many regions in China have carried out new energy market-oriented trading exploration, including direct trading of new energy and large users, new energy and thermal power generation rights trading, new energy cross-provincial medium and long-term trading, new energy cross-regional spot trading, and the establishment of a peak shaving auxiliary service market. This research takes typical new energy-rich provinces as an example to quantitatively analyze the effectiveness of the typical trading mechanism of new energy consumption in promoting new energy consumption. It is an inevitable trend to promote the consumption of new energy through market-oriented transactions. Combined with the construction process of China’s power market, the market will fully play the role of optimizing the allocation of resources, accelerate the construction of a power market-oriented trading mechanism that adapts to the consumption of new energy, and further utilize the market mechanism to promote new energy the role of energy consumption.

With the increase of new energy power generation, the requirement of smart grid and the popularity of electric vehicles, the research focus on V2G. With Electric vehicles being distributed energy storage or distributed generation, peak regulation in power system is involved in important functions of V2G. In order to achieve peak regulation function, the paper has analyzed the control relationship between the electric vehicles, V2G station and electric vehicle charge\ discharge control center, presented charge and discharge control strategy based on the two levels of electric vehicle charge\discharging control center and V2G station control layer and introduced algorithms and examples to achieve these strategies.

Demand Side Response

.In recent years, the development of new energy has become a bottleneck. As a high-quality demand side response resource that can be flexibly dispatched, thermal load can be used to promote the consumption and utilization of new energy. Based on the theory of peak valley electricity price and power demand response mechanism, this paper designs a demand response model of thermal price type, which uses time-sharing heat price to guide users to use heat orderly on the heating side. The simulation results show that the reasonable setting of heat price and satisfaction constraints of different heating modes can effectively change the heating mode of the user side and alleviate the contradiction between the supply and demand of thermal power, reduce the heating cost and realize the economic operation of the system.
