Abstract

In this paper, the control strategy for an overall microgrid is presented. The control has two main levels: (i) the droop control of the inverters, and (ii) the control of the static bypass switch, and the droop settings for the management of the power flow. Thus, a flexible microgrid is obtained to operate in either grid-connected or islanded mode. Results from line- interactive UPS inverters connected in parallel forming a microgrid are presented, showing the feasibility of the presented solution.
