Abstract

Due to the increased share of renewables in the power network, maintaining a stable network has become more challenging. The supply from the renewables is highly time-varying which causes fluctuations in the power network. In this thesis a new controller to regulate the power generation, based on two existing controllers, is tested for generality. The aim of this research is to solve the optimal power dispatch problem using the new controller with any strictly convex cost function. First the existing controllers and proposed controller are analyzed and simulated with linearized power dynamics in a four area power network. Then the proposed controller is simulated with three different strictly convex cost functions and randomized initial values. The results show that the controller is able to regulate the frequency deviation back to zero and the power generation to an optimum of the power dispatch problem. Therefore, it can be stated that the proposed controller is a good alternative to the existing controllers since it only needs frequency measurements to calculate the power generation and it can deal with more general strictly convex cost functions.
