Types of inverters and topologies for microgrid applications ABSTRACTInverters are the key actuator in the control of AC microgrids, since they manage the power flows of both the generators and energy storage devices. In general, there are three types of inverters depending on the control strategy: grid feeding inverters, grid forming inverters and grid supporting inverters. Those inverters can be implemented with different hardware topologies, each one of them with advantages and disadvantages. This paper presents a synthesis of the inverter topologies widely used in AC microgrids. Moreover, this paper also describes the inverters architectures and main control strategies.

Evolution of the Electricity Distribution Networks—Active Management Architecture Schemes and Microgrid Control Functionalities

“…The grid supporting inverters (GSIs) aim to maintain the power quality in the islanded microgrid by supplying active and reactive power with the droop controllers. The GSIs can be connected with the dispatchable DG units and the BESS units [102].…”

Robust Parallel Operated Inverters in Microgrid with SRF(Synchronous Reference Frame) – PLL(Phase Locked Loop) and SRF - Virtual Impedance Compensation Loop for Proportional Load Sharing

“…There are three types of inverters function wise in AC Microgrids. They are grid following or grid feeding, grid forming and grid supporting [3] .…”

Diseño de un Control de Corriente LMI para un Convertidor Modular Buck-Boost

“…La tensión obtenida en los sistemas de energía renovable, en su mayoría, presentan características DC no reguladas y por tal motivo existen los convertidores, encargados de regular la tensión del sistema [1], donde se tendrá una tensión mayor o menor a su salida en relación con la tensión de entrada. En cuanto a las topologías para estos convertidores, se clasifican en aislados y no aislados; dentro de los convertidores DC-DC no aislados se encuentran el Boost, Buck, Buck-Boost, Cuk y Sepic.…”
