Abstract

In this paper, we consider the problem of overvoltage arising in PV residential microgrids due to excessive power injection into the grid by the PV generators. We propose a decentralized switched controller to curtail excess active power in order to avoid overvoltage while considering the active power constraints. Under different power constraints the system will take different forms: LTI, switched or hybrid system. Convergence to the voltage limit is shown for all three cases.
