This article presents a comparison of three control strategies for managing active and reactive power, voltage, and frequency of power electronic inverters. The first strategy mimics the behavior of conventional synchronous machines, while the other two use the concept of droop control, which is a classic technique in power systems and microgrids. These three strategies have been implemented in a test system with a single inverter connected to an infinite bus. In addition, we propose a tuning strategy for generalized droop control based on optimal control theory for linear systems.
