Abstract

The invention relates to a frequency modulation and electric energy combined clearing method, device and apparatus in the power market, and belongs to the technical field of power system dispatching operation. The method comprises the following steps: acquiring boundary data required by electric power spot market transaction and standby auxiliary service arrangement; obtaining declaration data ofmarket members; according to the boundary data and the declaration data, enabling the electric energy and frequency modulation auxiliary service combined clearing model based on the reserve capacity constraint to perform combined clearing on the electric energy and frequency modulation auxiliary service; and optimizing the standby auxiliary service based on the optimized standby auxiliary servicemodel according to a combined clearing result of the electric energy and the frequency modulation auxiliary service. An electric energy and frequency modulation auxiliary service combined clearing model considering standby capacity constraints is utilized. Standby capacity constraints are considered in combined clearing of electric energy and frequency modulation auxiliary services. The problem that in the prior art, a summarized power generation resource decision-making mechanism is not coordinated is solved, electric energy, frequency modulation and standby operation plans of a generator setmeet the requirement for safe operation of a power grid, and the safety of power grid dispatching operation is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power system dispatching operation, and in particular relates to a method, device and equipment for combined frequency regulation and electric energy clearing in the electric power market. Background technique [0002] The electricity spot market is an important part of the electricity market system, and together with the medium and long-term market, it plays the role of electricity commodity price discovery. The rapid development of the electricity spot market has promoted the change of the joint optimization mechanism of electric energy, frequency regulation, and ancillary services. [0003] At present, the joint optimization or joint clearing of electric energy and frequency regulation, backup auxiliary services is a key issue in the field of power system dispatching and operation. Under the power generation plan control mode, the dispatching organization is responsible for coordinating the p...
