摘　　要：针对电力市场环境对AGC的影响问题,以三区域互联电力系统为研究对象进行讨论。首先,构建三区域互联AGC模型,对模型预测控制在AGC中的应用进行了分析;然后,考虑到MPC在不同系统中控制效果的差异性,提出了一种基于系统补偿的控制方法,拟通过补偿环节的设计以改变系统结构,使MPC能够适应控制对象的变化;在此基础上,根据电力市场环境下配电网与发电厂签订供电合同的两种控制需求,在AGC系统中增加配电网参与矩阵以及区域参与矩阵的概念,对所提方法进行验证。MATLAB仿真表明,相比于传统MPC,增加补偿环节后系统能够具备更好的控制效果。The deregulated power market has brought new challenges to the traditional automatic generation control(AGC).In this paper,the influence of the power market environment on the AGC was studied with the three-area interconnected power system as the research object.First,the three-area interconnected AGC model was constructed,and the application of model predictive control(MPC)in AGC was analyzed.Then a control method based on system compensation(CPS)was put forward.It was designed to change the system structure through the design of compensation link,so that the MPC controller has better control effect.According to the power market environment,the two control requirements of the power supply contract between the distribution companies(DISCO)and the generation companies(GENCO)were taken as an example to verify the proposed method.And the concept of the DISCO Participation Matrix(DPM)and the Area Participation Matrix(APM)was added in the AGC system.The MATLAB simulation shows that the system can have better control effect compared to the traditional MPC after the increase of the compensation link.
