Study on the construction of auxiliary service market under largescale new energy access

Abstract

At present, all countries are accelerating the construction of a new type of power system based on renewable energy, and the random volatility and intermittency of new energy resources, and the low resistance and weak support of new energy power generation and grid-connected equipment exist objectively. In order to maintain the safe and stable operation of the power system, the demand for auxiliary services such as frequency regulation, peak regulation, voltage regulation, standby and black start is increasing. Therefore, with the increase of new energy penetration rate, it is necessary to explore the impact of the increase of new energy penetration rate on the cost of auxiliary services. Combined with the background that the foreign power market has been running for a long time, auxiliary service varieties are more abundant, and the new energy penetration rate of some countries or TSOs has reached a higher level, the author has conducted a study on the impact of the increase in the penetration rate of new energy on the cost of auxiliary services in foreign countries, explored the impact of the increase in the penetration rate of new energy on the cost of auxiliary services, and provided reference and guidance for the classification of auxiliary service products, the design of pricing mechanism and other key issues of the construction of the auxiliary service market in China. The study explores the impact of the increase of new energy penetration on the cost of auxiliary services, and provides reference and guidance for the division of auxiliary service products, design of pricing mechanism and other key issues of auxiliary service market in China.
