As the penetration of electric vehicles increases the number of chargers for these vehicles are also increasing and therefore, will increase the electric energy grid consumption. To integrate these needs with the green energy, the use of electric chargers with a solar photovoltaic installation makes perfect sense. However, these charges can also be used for the support of the reactive power compensation...
As a distributed generation system increases, a stable power supply becomes difficult. Thus control of power leveling (PL) unit is required to maintain the balance of power flow for irregular power generation. The unit is required to respond to change of voltage and bidirectional power flow. So the bidirectional buck/boost DC/DC converter is applied for the control of PL unit in this research. The...
This paper presents a basic sensitivity analysis of the conversion losses in a dc microgrid by varying the system parameters. A simple residential apartment with 20 units with a photovoltaic (PV) system is taken for the analysis. The conversion losses are calculated with the measured electricity consumption and the estimated output of the PV system. Modelica, an object-oriented modeling language,...
This paper is mainly concerned with the development of a new state-of-the-art prototype, high-efficiency, phase-shift, soft-switching, pulse-modulated, full-bridge DC-DC power converter with a high-frequency power transformer, which is designed for utility-grid-tied photovoltaic (PV) power inverters. The proposed high-frequency transformer (HFTR) link DC-DC converter topology is based on a new conceptual...
