Abstract

The invention discloses a day-ahead power spot market clearing method, system and device and a storage medium. The method comprises the steps of determining a unit startup combination through a safetyconstraint unit combination model, and obtaining a frequency modulation plan according to the unit startup combination and a frequency modulation market rule; determining a standby plan according tothe standby capacity, the standby quotation and the security constraint standby clearing model; and determining a unit power generation plan according to the unit startup combination, the frequency modulation plan, the standby plan and the safety constraint economic dispatching model. According to the embodiment of the invention, the standby capacity market which is relatively independent from theelectric energy market and the frequency modulation market is constructed, the real-time condition of the standby capacity is fully considered, and standby resources can be efficiently scheduled, sothat a reasonable, reliable and high-executability power generation plan is obtained, the stable operation of a power system is ensured, the power generation efficiency of the power system is improved, and the method can be widely applied to the technical field of power markets.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a method, system, device and storage medium for clearing the day-ahead electric power spot market. Background technique [0002] The backup service is an indispensable and important technical means to ensure the reliability of the power system, and its commercialization will help provide a new way for the system to obtain sufficient backup services. Due to the differences in the supply capabilities and costs of service providers, it is feasible to introduce competition into the field of backup services, and the introduction of competition to form prices will help motivate backup service providers to improve efficiency and carry out technological innovation. The establishment of the backup service market can help equipment owners to coordinate between the provision of electric energy and the provision of backup services, and can make the opportunity cost, operating c...
