Study Of Circulating Current Phenomena In Multiple Parallel Inverters Operating In Microgrid

Now a days, renewable energy is used as an alternative way of generating clean energy. Increasing use of ‘green’ energy benefits the global environment and hence makes it a global concern. Literature review indicates that, microgrid (MG) can offer a power system with features like increased reliability, flexibility, cost effective and efficient energy. The parallel operation of small inverters gives modularity to the system and provides extra reliability and redundancy. This paper deals with study of circulating current phenomena in parallel inverters. Accurate power sharing means minimization of the circulating current among the modules. However the issues related to synchronization of parallel inverters, power sharing amongst the inverting units and minimization of circulating currents still remains an important topic for research.
