dc.description.abstractThe project aims at investigation and development of multiple-bus hybrid alternating current/direct current (AC/DC) distribution network for future communities to increase efficiency and reduce cost. Multiple types of AC and DC distribution network topologies were discussed to find out about their advantages and disadvantages. Typical semiconductor devices used in power electronics were discussed to find out about the key factors which can affect power conversion efficiencies. Operations in line frequency rectifiers, DC-to-DC converters and power inverters in power electronics were investigated and analyzed with different circuit topologies, with focus on their conversion efficiencies. Key variables such as firing angle of controllable switches and line inductance were considered in the calculation of conversion efficiencies. Several resonant power converter topologies used in residential and industrial applications were simulated in MATLAB and analyzed. Simulation results from MATLAB have shown that resonant power converters provide high conversion efficiencies in residential and industrial applications. Photovoltaic (PV) array sizing was done by calculating the maximum electricity consumption of a typical resident household, as well as analyzing the technical specifications of a solar panel PV. PV array sizing serves as the basis for its simulation in MATLAB, which was performed to access its efficiency using Maximum Power Point Tracking (MPPT) algorithm in AC distribution network. Simulation results prove that MPPT varies the PV's reference DC voltage during changes in the solar irradiation, in order to extract maximum power from the PV array. Finally, a hybrid AC/DC network was proposed for higher conversion efficiency.en_US
