WAM-based hierarchical control of islanded ac microgrids

Abstract

This chapter presents a wide area measurement system (WAMS) based hierarchical control of islanded AC microgrids (IACMGs) with static and dynamic loads. The proposed WAMS-based hierarchical controller consists of a lower-level decentralized controller, for each inverter-interfaced distributed generation (IIDG) unit, accompanied by an upper-level multi-input-multi-output (MIMO) centralized controller. Furthermore, this chapter also analyzes the impact of signal transmission time delays on the performance of the proposed WAMS-based hierarchical controller by performing simulation study on its application to the typical IACMG system. © Springer Nature Switzerland AG 2021.
