Abstract

The invention discloses a frequency modulation auxiliary service market clearing calculation method considering unit frequency modulation performance. The method comprises the steps of sorting units participating in frequency modulation clearing, and forming a unit clearing sequence, and sequentially conducting frequency modulation performance verification, unit state verification, adjustment margin verification, manual intervention verification and total clearing capacity verification according to the unit clearing sequence. According to the method, the unit frequency modulation performance is considered in frequency modulation market clearing calculation, the high-quality frequency modulation performance unit is selected for frequency modulation on the basis of meeting the power system frequency modulation requirement, the frequency modulation service supply cost is reduced, the enthusiasm of a power generation enterprise to provide frequency modulation auxiliary service resources is helped to be aroused, and stable operation of the frequency modulation auxiliary service market is promoted.

Description

technical field [0001] The invention relates to a frequency regulation auxiliary service market clearing calculation method considering the frequency regulation performance of a unit, and belongs to the technical field of electric power system dispatching automation. Background technique [0002] Frequency is an important index to measure power quality. Automatic Generation Control (AGC) is the main means to realize power and frequency control of the interconnected grid, and its control effect directly affects the quality of the grid. The AGC unit is the main provider of frequency regulation services. In the traditional way, the frequency adjustment of the AGC unit is only for the purpose of ensuring the stability of the power system operation. The way to allocate frequency adjustment tasks is not considered from the perspective of economy and unit frequency adjustment performance. With the in-depth reform of my country's power operation system and the acceleration of the c...
