From the perspective of global warming suppression and depletion of energy resources, renewable energies, such as solar collector (SC) and photovoltaic generation (PV), are getting attention in distribution systems. Then, all electric houses with PV and HP are becoming widely used recently because of using time-of-day electricity rate system. If fixed battery can be introduced in the houses, the electricity...
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 proposes the power management unit used for the dc feeder in a house. The simulation results show the 7% reduction of the battery Wh rating.
This paper presents a simulation model of green energy devices, which is developed for analyzing energy balance of a micro-grid and for optimizing its management. Several renewable energy based electricity production and storage are modeled and analyzed in the making of strategies for sustainable micro-grid management. In this study, two different simulation models are described, which call a “long-term...
Abundance sunlight ray in Malaysia makes it perfect to be used with the current alternative green vehicle technology: the Light Electric Vehicles (LEVs). LEV is powered by battery packs, which can be rechargeable by any external source of electricity. Hence, it is one of the targets of this study to examine the reliability of such solar fuel station. As green alone is not enough to be the purchasing...
