Abstract

Energy fulfilment by consumers independently by utilizing renewable energy, PV, has greatly improved and has been developed in the form of a Smart Isolated Microgrid (SMG) system. The need for electrical energy is no longer dominated by AC loads but also by DC. So, the application of power electronic devices is very helpful in supplying energy. This study uses a bidirectional converter system that is able to regulate the power flow from DC to AC microgrid or vice versa, by maintaining the quality of the voltage of the two microgrids. The SMG system modelling uses MATLAB-Simulink simulation and shows good performance. As the result of the SMG system simulation, the bidirectional converter works well as a maximum energy transfer device for RES-PV and fulfils AC and DC loads by acting as a rectifier and inverter. The results show the stability of the bus voltage is good. DC bus voltage drops by 4.25% and AC bus voltage below 10% of the voltage set by each bus. Total Harmonic Distortion (THD) is also low with a voltage THD value of 0.65% and a current THD value of 1.38%. The AC load and grid sides have very good current THD values, namely 0.37% and 0.17%.
