In a coal-fired power generation system, energy efficiency is increasingly focused on due to the fact that the key indices of power plant such as coal cost and emission are closely related to energy efficiency. However, many coal-fired power plants lack effective energy efficiency program due to: diversified unit equipment type, insufficient or outdated original parameter setting, or diversified operation...
Building load profiling plays an important part in the development of optimal energy management systems. Heating, Ventilation, Air Conditioning (HVAC) systems consume around 40% to 50% of the total energy consumed by buildings. Using this load data, optimal operation scheduling can be determined to reduce the peak energy requirement and minimize the overall energy consumption. In this paper, EnergyPlus...
In recent decades there has been a wide spread of renewable energy system due to environmental demands. Consequently due to the nature of the renewable energy system, it is efficient to use distributed generation in electrical power system. Therefore, this paper articulates the energy efficiency of low voltage direct circulating (DC) distribution system. There are two case studies taken into consideration...
As the number of DC loads are growing in our daily uses, the low voltage DC (LVDC) distribution system is becoming important. Power supplied through the low voltage AC (LVAC) distribution system needs both the AC/DC rectifier and the DC/DC converter to supply the DC loads. In comparison, LVDC system would only need the DC/DC converter to supply the DC loads. Integration of renewable energy sources...
Application of renewable sources of energy is vital for the mankind due to global warming. Residential buildings consume major portion of electricity. Therefore, a grid-connected photovoltaic system of domestic level with battery storage backup (PV/storage system) is addressed in this article. This system has a significant effect on decreasing energy costs and contributes to meet the requirements...
