Description
Basically, droop control is not actually a controller, but it is a concept in which, inverters are assumed to operate on the basis of their capacities. Droop based VSI (voltage source Inverter) are more effectively used where different Renewable Energy Source ( RES) are connected in parallel. For this operation, the inverter is to be controlled for which, PI and PR controller can be used. In droop Controlled Voltage Source Inverters, It is the general trend to increase the electricity production using distributed power systems. An AC Micro-Grid system transfers the DC power from a Distributed Energy Resource (DER) unit, for example, a photovoltaic (PV) solar array, wind-power, or a fuel cell transfers power to the utility grid and it has the capacity to operate autonomously. To achieve good power sharing and wireless communication between renewable energy sources, one of the most popular approaches is to employ droop control for active and reactive power regulation. The renewable energy sources can meet the new load requirements in a manner determined by its frequency and voltage droop characteristics.
