Problems solved by technology

However, the single-agent method does not consider the actual situation of other regional interconnected grids, and only performs local optimization according to itself
When some areas cannot be controlled according to their own optimization control area control error (Area Control Error, ACE) within the allowable range, this kind of method cannot realize the cooperative control of different areas

Embodiment

[0072] This embodiment is based on the overall framework of the China Southern Power Grid, with Guangdong Power Grid as the main research object. The simulation model is a detailed full-process dynamic simulation model built for the actual engineering project of the Guangdong Electric Power Dispatching Center. For detailed model parameters and simulation design principles, please refer to "Dynamic Optimal CPS Control of Interconnected Grid Based on Q-Learning" published by Tao, Zhou Bin, and Chen Jiarong (Proceedings of the Chinese Society for Electrical Engineering), see Figure 5 shown. In this simulation model, the China Southern Power Grid is divided into four regional power grids of Guangdong, Guangxi, Guizhou and Yunnan. The sampling time of Guangdong Power Grid and other provincial power grids is 15 minutes, and the amplitude does not exceed 1500MW (corresponding to the largest single fault of Guangdong Power Grid - DC single fault). Pole blocking) finite broadband whit...

Abstract

The invention discloses an intelligent electricity generation control method based on an intelligent body equalization algorithm. The method comprises the steps of (1) analyzing system characteristics, determining a state discrete set S, (2) determining a joint action discrete set A, (3) collecting the real-time operating data delta f and delta P of the power grid of each area when each control cycle is started, calculating the instantaneous value of ACEi(k) and the instantaneous value of CPSi(k) of each area, (4) obtaining an instant reward value of the power grid i of each area through a current state s, (5) solving relative equalization linkage strategies through linear equalization and selected equalization selection functions, (6) executing corresponding operation on all the power grids j of all the areas, and (7) returning to the step (3) when a next control cycle comes. The intelligent electricity generation control method based on the intelligent body equalization algorithm has the advantages that better equalization points can be found in a control process, the capacity of coordination electricity generation of the power grids of all areas is improved, and the stability and the robustness of a power system are improved remarkably.

Description

technical field [0001] The invention relates to an intelligent power generation control technology of a power system, in particular to an intelligent power generation control method based on an intelligent body balancing algorithm. Background technique [0002] The modern power grid has developed into an interconnected system with multiple control areas based on the power market mechanism. Automatic Generation Control (AGC) is the main means of power and frequency control in the interconnected grid, and its control effect directly affects the quality of the grid. The power deviation and frequency variation of the tie line in the interconnected power system change with the change of the load on the user side. How to track the random change of load and improve the frequency quality of the power grid by controlling the active output of the generator is a hot issue in the field of control today. Automatic power generation control is a closed-loop control system based on dispatc...
