Abstract

In this paper, a modelling method for the parallel operation of inverters in a micro-grid system is proposed. Conventionally, the droop method has been applied to achieve a simple structure and no-interconnections among power sources. The small signal model of the wireless parallel inverter allows obtaining the behaviour of the system in function of frequency and voltage droop. The model is simple and eases to unstainable, and can give reference to the next step for the dynamic stability analysis and dynamic equivalency in power system. Simulation has been carried out on the system with two inverters in parallel. The results have validated the model developed.
