Multi-unit automatic generation control frequency modulation method for thermal power plant and related device

Abstract

The application discloses a kind of thermal power plant multi-unit automatic generation control frequency modulation method and related device, comprising: 1) form operating information;2) form frequency modulation instruction limit;3) based on the list of participating frequency modulation unit establishes landing discrimination model TCPG;4) under the constraint of frequency modulation instruction limit, instruction sample distribution is established, and candidate frequency modulation instruction is generated from instruction sample distribution sampling;5) candidate frequency modulation instruction is input landing discrimination model, and landing score is calculated, and high-score candidate is screened based on landing threshold;According to high-score candidate, instruction sample distribution is updated according to CEM, and final frequency modulation instruction combination is determined from updated instruction sample distribution;6) according to final frequency modulation instruction combination, generate and issue automatic generation control frequency modulation instruction, receive corresponding frequency modulation instruction execution feedback, and update latent variable response state parameters according to frequency modulation instruction execution feedback, which can form thermal power plant multi-unit AGC frequency modulation instruction combination, and realize rolling closed loop.
