Real-time control method of power grid active power taking into account regulation characteristics and economic and environmental performance

Abstract

The invention discloses a real-time active power control method for a power grid that takes into account both regulation characteristics and economic and environmental protection performance. Operate in an independent circulation mode according to their respective set periods, and set the time limit for avoiding frequent fluctuations in active power according to the adjustment characteristics of each power plant. By aiming at the optimal economic and environmental performance of power generation, taking into account power balance and transmission equipment Real-time control strategy optimization calculation of grid active power with capacity, stable section limit, and frequency and peak regulation constraints. According to the sensitivity of the adjustment time limit for frequent fluctuations in active power to the objective function, decide whether to relax the adjustment time limit for frequent fluctuations in active power of the power plant and realize the regulation characteristics of the power plant. Both economic and environmental performance are taken into consideration.

Description

Technical field [0001] The present invention belongs to the field of power grid scheduling operation and control technology, and more particularly, the present invention relates to a grid, and a power grid that is equipped with power plant adjustment characteristics and economic environmental performance control methods. Background technique [0002] In order to respond to changes in the power generation capacity of the grid and the power generation capacity in the grid, the power plant will be adjusted. In the control decision calculation of power grids, it is necessary to meet the power balance requirements, considering the constraints such as power transmission equipment, stabilize and defrared limit and frequency modulation peaks in the grid, but also consider the adjustment characteristics and economic environmental performance of power plants. [0003] Different types of power plants are different, even if the same type of power plant regulation characteristics are differen...

Problems solved by technology

[0004] As for how to take into account the regulation characteristics and economic and environmental performance of the power plant, the existing real-time active power control technology of the power grid is to keep the active power output of the power plant unchanged within the set time limit as a constraint condition for decision-making optimization, and there is no adjustment based on the active power of the power plant. The degree of influence of the overall economic and environmental performance of grid power generation on the regulation characteristics of power plants is treated as a "soft constraint"
