Abstract
This research work presents the comparative study of the performance of constant IQ droop, Constant Q and voltage Q droop controller on a dispatch controlled optimized hybrid grid tied microgrid system having electrical, industrial and EV (electric vehicle) loads. The optimized configuration of the microgrid on top of load following (LF) and cycle charging (CC) dispatch methods have been determined using a propri-etary derivative free algorithm and their voltage, active power, frequency and reactive powers have been evaluated for the three different control strategies. For the planned microgrid, it has been determined through the analysis in the proposed location, the two dispatch strategies offer similar optimization results and constant IQ droop control offers slightly better performance among the others. The results demonstrate the feasibility of the microgrid system with the proposed controller and operating strategy.
