【 摘 要 】

Load shedding control is one of the key technologies for stable operation and efficiency optimization control of power system. Aiming at optimized load overcut rate optimization problem for second/minute level precision load shedding efficiency, a precise load shedding control method based on user demand response clustering is proposed. Firstly, based on the analysis of the characteristics of the precise load control system, the authors construct the optimal mathematical model of the precision load shedding control strategy with minimum load overcut rate using the user load clustering. Secondly, the particle swarm algorithm is used to achieve the minimum load overcut rate control strategy model. Finally, through the analysis of the example, the proposed method can reduce the 30% load over-cut rate and the load over-cut rate volatility compared with the traditional method, and verify the effectiveness of the proposed method.
