基于PI控制的电力市场短期均衡模型

利用电力市场价格与发电量之间互相影响的循环特性,将控制理论知识引入到短期电力市场模型中,建立了基于PI控制的短期电力市场古诺均衡模型,并将微分方程转变成传递函数形式,从而得到整个电力市场古诺模型的传递函数,判断出系统均衡解稳定的充分条件。最后,本文利用Matlab工具,以IEEE30节点6发电机作为测试系统求解电力市场短期均衡解,结果表明电力市场引入PI控制器后,即使市场均衡条件发生变化,系统依然能够快速获得新的均衡解。

Power market short-term equilibrium model based on PI controlling

In this paper,a short-term equilibrium model based on PI controller is set up.With the application of control theory,sufficient conditions are presented.With MATLAB,the IEEE 6-generator 30-bus system is used to demonstrate the proposed method.Results show that after introducing PI controller into the proposed equilibrium model,power market equilibrium can be got easily and stably even when power demand is changed suddenly.
