dc.description.abstractDC microgrid had gained its popularity into the modern world with the increased in DC loads globally. The advancement of the semiconductor technology had made power conversions in Direct Current (DC) much reliable and efficient. Energy Storages (ESs) were used in the DC microgrid to mitigate the variations between the loads and the generations. However, different type of ESs, such as batteries and ultracapacitors, exhibit different characteristics and had different properties. Thus, a Hybrid Energy Storage System (HESS) implementation would be beneficial for the operation to attain optimal response with the complementary properties of different ESs. With multiple ESs connected, an Energy Management System (EMS) would be required to manage the power distribution and State of Charge (SoC) restoration of the ESs. This project will conduct studies on different control algorithms to manage the HESS in a DC microgrid. The droop control, which was done to achieve power sharing between batteries. An integral droop control, which puts the ultracapacitor in standby during steady state operation due to its low energy capacity. The SoC restoration, during transition, of the ultracapacitor would also be explored using an improved integral droop control with an additional level of control. The setup of the project consists of triple ESs with triple boost converters integrated to a common DC bus to simulate a DC microgrid. dSPACE DS1006 processor module was used for the implementations of the control algorithm that was built in the MATLAB Simulink and dSPACE Control Panel.en_US
