Modelling and Control Optimization of Diesel Synchronous Generators in LV Microgrids

Abstract

This work investigates the power sharing of distributed energy resources, such as diesel synchronous generators and inverter-coupled batteries, in islanded microgrids after load transients. Firstly, the necessary accuracy of the diesel synchronous generator model for dynamic simulation and small signal stability studies is examined. Secondly, the controller parameters are optimized deploying a genetic algorithm to enhance the transient load sharing between synchronous generators and battery inverters.
