This paper investigates small signal stability and designing advanced centralized control to enhance robustness and dynamic performance of a modern distribution system with high penetration of distributed generators (DG). The paper mainly concerns comparison of classical, H 2 and H ∞ control strategies on system stability. The target performance is to satisfy stability of the system and improve nominal performance of DGs. Therefore, first we design a base controller for the system using classic control. Then, H 2 and H ∞ control systems are designed in order to warrant both nominal stability and dynamic performance of the system. Finally, the results of three control strategies are compared and the general findings of the paper are discussed.
