Study On The Transaction Mode Of Frequency Regulation Auxiliary Service Market In Power System With High Proportion Of Renewable Energy

With the high proportion of renewable energy connected to the system,the construction of clean energy system has been steadily promoted,but it also brings some problems,especially the frequency stability problem.Therefore,the establishment and improvement of auxiliary service market has become a new way to solve China’s electricity energy transformation.At present,China’s electricity market reform is in the stage of development.The electricity market and auxiliary service market complement each other.To speed up the construction of frequency regulation auxiliary service market has become a key link of power market reform.At the same time the design complete ancillary services market transaction mode is an important part of the electric power market construction,steadily push forward the electric power market main body to join the market,foster the subject of kinds of electric power market,to arouse the enthusiasm of market participants frequency regulation,promote electric power market pattern diversification,improve product quality of frequency regulation,reduce system frequency regulation expense,Improving market conditions significantly improves overall social welfare.This paper first analyzes the transaction process of the frequency regulation auxiliary service market,and makes a detailed review and introduction of the organization of the frequency regulation auxiliary service market,the invocation of frequency regulation auxiliary services,the construction of frequency regulation performance indicators,and the compensation of frequency regulation auxiliary services.The difference between the construction of frequency regulation performance indicators and the way of cost compensation in the service market,the research on the transaction mechanism of the frequency regulation auxiliary service market of the power system is carried out,which lays the foundation for the establishment of the frequency regulation auxiliary service transaction mode;Secondly,the frequency regulation reserve capacity demand model is established,and the frequency regulation reserve capacity Determination is a prerequisite for frequency regulation market transactions,analyze the probability distribution characteristics of wind power and load fluctuations in the minute-level scale,and the frequency regulation demand brought by it,deduce the frequency regulation reserve capacity determination method for systems with high wind power penetration,and obtain The relationship between frequency regulation reserve capacity and wind power penetration rate in systems with high wind power resource penetration;further from the perspective of market operators,an electric energy-frequency regulation joint transaction model is designed that considers frequency regulation resource differences and frequency regulation performance indicators,making it easier to participate in fast frequency regulation resources In the market,the frequency regulation reserve capacity demand model is brought into and the clearing model is improved,and the market clearing model is improved.Compensation effect of electricity price compensation method on frequency regulation resources,and summarizes the influence of various clearing and compensation methods on the enthusiasm of market participants for frequency regulation and the degree of frequency regulation compensation;The service market transaction mode is established,and the joint optimization decision-making model of wind power and thermal storage electric heating is established.In this mode,wind power and thermal storage electric heating are combined as participants in the frequency regulation market.The analysis of examples shows that the benefits of both are improved under the joint operation mode.The effectiveness of the proposed operation mode is analyzed,and the influence of the frequency regulation market clearing price and electric heating heat load demand on the operation strategy of the consortium is analyzed.Provide guidance on operations.
