Problems solved by technology

[0003] At present, my country has preliminarily established power market auxiliary services such as conventional power supply deep peak regulation, but the research on the primary frequency regulation auxiliary service market is not enough. In particular, the primary frequency regulation performance of multiple types of power supplies is significantly different, and the output performance during transient periods is different. The contribution is also different. In addition, because the system itself has a certain ability to resist frequency disturbances, under different frequency change depths and dynamic stages, the power grid's demand for frequency modulation services will show great differences, resulting in changes in supply and demand relationships, directly affecting services. price

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, and in particular relates to an energy-based primary frequency modulation auxiliary service market transaction settlement method, and also relates to an energy-based primary frequency modulation auxiliary service market transaction settlement device. Background technique [0002] With the development of large-scale new energy sources and the development of high-voltage direct current transmission, the degree of power electronics in my country's power grid is getting higher and higher, and the proportion of conventional power sources continues to decline, resulting in prominent frequency problems in both the sending-end power grid and the receiving-end power grid. In order to alleviate the system frequency limit and stability problems under severe faults such as grid DC blocking, in addition to frequency support through traditional conventional power sources, t...
