Abstract

The invention discloses a unit primary frequency modulation capability evaluation method and system based on edge calculation, and the method comprises the steps: obtaining the initial information data of a conventional power supply, and building an initial generator set primary / secondary frequency modulation model according to the initial information data; acquiring real-time information data, updated in real time, of a conventional power supply, training the primary / secondary frequency modulation model of the initial generator set based on the real-time information data, and performing action response of primary / secondary frequency modulation by the generator set according to a trained output result; and evaluating the primary frequency modulation capability upper limit of the unit in real time according to the action response of primary / secondary frequency modulation.

Description

technical field [0001] The present invention relates to the technical field of power system operation and control, and more specifically, to a method and system for evaluating the primary frequency regulation capability of a unit based on edge computing. Background technique [0002] The real-time power balance characteristic of power system makes generation control an important research topic. The grid frequency is a key parameter that affects the stable operation of the power system. The goal of power generation control is to balance the power between the generator and the load while adjusting the grid frequency stability. The frequency regulation methods of the power grid mainly include primary frequency regulation and secondary frequency regulation. On the whole, the characteristics of the primary frequency regulation of the power system are related to the characteristics of all generating units operating in parallel, and are also related to the working conditions of the...
