Power grid active power real-time control method considering both regulation characteristics and economic and environmental protection performance

Abstract

The invention discloses a power grid active power real-time control method considering both regulation characteristics and economic and environmental protection performance. The power grid active power real-time control method is characterized in that the power grid active power real-time control method comprises a power station real-time active power output acquisition module, a sensitivity calculation module, a control strategy calculation module and a control strategy module; the above four modules independently and circularly operate according to the respective cycles thereof; a time limitfor avoiding active power frequent fluctuation adjustment is set according to the adjustment characteristics of each power station; relaxing of the power station active power frequent fluctuation adjustment time limit demand can be determined by using the optimized economic and environmental performance of power generation as a target, and power grid active power real-time control strategy optimization calculation of power balancing, the transmission device capacity, the stable cross section quota, and frequency-modulation peak-shaping constraints and according to the sensitivity of the active power frequent fluctuation adjustment time limit change to a target function, the consideration of the power station adjustment characteristics and the economic and environmental performance.

Description

technical field [0001] The invention belongs to the technical field of power grid dispatching operation and control. More precisely, the invention relates to a real-time active power control method of a power grid that takes into account both the regulation characteristics of a power plant and the economic and environmental protection performance. Background technique [0002] In order to cope with changes in the load in the grid and the power generation capacity of new energy grid-connected stations, it is necessary to adjust the output of power plants. In the decision-making and calculation of real-time control of active power in the power grid, not only the requirements of power balance must be met, but the constraints of power transmission equipment capacity, stable section limit and frequency regulation and peak regulation in the power grid must also be considered. [0003] Different types of power plants have different regulation characteristics, even the same type of ...

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"
