Real-time generation schedule and closed-loop control evaluation analysis method thereof

Abstract

The invention discloses a real-time generation schedule and a closed-loop control evaluation analysis method thereof. The closed-loop control evaluation analysis method is characterized by comprising the following steps: determining the real-time generation schedule and closed-loop control unit cluster classification; calculating a real-time generation schedule (CGS) regulating standby demand index; calculating a real-time generation schedule regulating standby adequacy index; calculating a power grid security monitoring index; calculating a real-time generation scheme closed-loop control depth index. The real-time generation schedule and the closed-loop control evaluation analysis key indicator and calculating method thereof are scientific and reasonable; the closed-loop control effect is objectively evaluated, and the tracking situation of the generation unit to the real-time scheme is analyzed online and immediately fed back, so as to form the more effective closed-loop control strategy, improve the real-time power grid running risk response capability, meanwhile reduce the manual intervention of scheduling operators and the frequently repeated regulating situation of a lot of units, prolong the service life of the generator unit, and improve the economic benefit of a power plant.

Description

Technical field [0001] The invention belongs to the field of power system dispatch automation, and relates to a real-time power generation plan and a closed-loop control evaluation and analysis method thereof. Background technique [0002] In recent years, the coordinated and rapid development of my country's UHV and all levels of power grids is gradually forming a super-large AC and DC power grid. As the power network becomes larger and larger, the operation of the power grid is becoming increasingly complex, and the pressure of peak and frequency regulation is increasing. The operation mode of different control target units changes frequently. To improve the control quality of automatic power generation control (AGC), it is necessary to rely on real-time power generation plan to perform three grid frequency adjustments according to the system load trend, adjust and track the power generation plan of the planned unit, avoid frequent adjustment of the unit and unreasonable allocat...

AI Technical Summary

Problems solved by technology

At present, the real-time power generation plan and its closed-loop control are still in the stage of in-depth research and trial, lack of a comprehensive, reasonable and targeted evaluation and analysis index system, and it is difficult to make a scientific and objective evaluation of the closed-loop control effect
