Problems solved by technology

In the past, the performance measurement method of manual or automatic response test was only used to measure a small number of time periods or individual instruction processes of the power generation unit, which could not meet the requirements of automatic performance measurement and calculation of each clearing period of the power generation unit. Instead, disturbance tests or test instructions were used. Frequency modulation performance measurement will affect the fairness among frequency modulation ancillary service providers in the market environment, therefore, traditional performance measurement methods are not suitable for frequency modulation ancillary service market environment
At the same time, when the traditional performance measurement method measures the regulation rate of the power generation unit, it generally calculates the regulation rate of the power generation unit according to a fixed cycle, and the calculation result of the rate index obtained is unstable and inaccurate
