A Study on Islanded and Parallel Operation of Inverters in a Microgrid Using Droop Control Strategy
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
Microgrids (MG) have gained major importance in the recent years, where much attention is given to the control of microgrid. In this context, this paper presents the droop control strategy in an islanded microgrid. Initially, the MG is operated in grid connected mode, where it is later switched to autonomous operation. The droop control technique is used to control the voltage and frequency under varying load conditions. Further, to realize the effectiveness of the control method, a system with parallel inverters is designed to share the load equally among the inverters. The model of the microgrid is designed and implemented in MATLAB/Simulink enivironment. Finally, the simulation results shows the effectiveness of the droop control in controlling the frequency, as well as equal load sharing is realized when inverters are operated in parallel.
