随着现代电力系统的自动化、智能化水平不断提高,电力系统的动态性越来越强。现代电力系统不仅包含非线性动态,还包括一些离散事件以及相应的操作变量。由此可见,电力系统是一个复杂化、多样化的混合系统。利用动态模型和仿真模型来描述电力系统的非线性动态、离散事件以及相应的操作变量,综合各类模型,建立电力系统的混合系统模型。针对电力系统的混合系统模型,将显示模型预测控制技术应用于电力系统中,对电力系统的电压进行及时有效的控制,能够提前预测并避免电力系统电压崩溃,还能对电力系统故障做出快速反应,充分证明了该方法的科学性、合理性以及有效性。
With the automation and intelligentization of modern power system, the dynamic of power system is getting stronger and stronger. Modern power systems contain not only non-linear dynamics but also discrete events and corresponding manipulated variables. Thus, the power system is a complex and diversified hybrid system. The dynamic model and the simulation model are used to describe the nonlinear dynamic and discrete events of the power system and the corresponding operating variables. The hybrid system model of the power system is established by combining various models. Aiming at the mixed system model of power system, the model predictive control technology is applied to the power system to control the voltage of the power system in time and effectively, which can predict and avoid the power system voltage collapse in advance and make the power system fault fast Reaction, fully proved that the method is scientific, reasonable and effective.
