ABSTRACT
In this chapter, a new control scheme of secondary voltage and frequency control based on a discrete-time neural inverse optimal distributed cooperative structure is introduced for islanded microgrids. A neural adaptive secondary controller for each distributed generator (DG) is developed to achieve the desired goals. The designed controllers are composed of an on-line neural identification scheme on the basis of an RHONN using the EKF and a nonlinear control strategy. Additionally, the control scheme does not require information of all installed distributed generators, nor a distributed generator model, which improves reliability. The controllers are verified through simulation for an islanded AC microgrid.
