This paper presents a robust control strategy for the autonomous operation of a microgrid consisting of electronically coupled distributed generation (DG) units. The DG units are connected to a point of common coupling, and supply a load, which can be unbalanced and/or nonlinear. In practice, the load is usually unknown in terms of network topology and parameters. However, it is assumed that the load...
This paper presents a comprehensive control scheme for the autonomous operation of a dc microgrid with high penetration of single-phase and unbalanced ac loads. An oscillatory component is introduced into current of dc microgrid through inverter-connected single-phase ac or three-phase unbalanced loads. In such a condition, a conventional droop controller cannot appropriately share the oscillatory...
