Robust Multi-objective Control-Based Frequency Regulation

This chapter formulates the proportional integral‐based frequency control problem with communication delays as a robust static output feedback optimization control problem. The H2/H∞ control is used via an iterative linear matrix inequalities algorithm to approach a suboptimal solution for the assumed design objectives. The proposed method was applied to a control area power system through a laboratory real‐time experiment. Finally, the genetic algorithm, as a well‐known optimization technique, is successfully used for tuning of PI‐based frequency control loop by tracking the robust performance indices obtained by mixed H2/H∞ control design.
