More electric technologies (METs) play an important role in meeting ever-growing demands for energy efficiency and emission reduction in the maritime transportation sector. As a result, ships with electrical power transmission are becoming popular compared to traditional mechanical power transmission based ships. Hybrid electric propulsion is an intermediate step in this trend where both mechan...
The interest in energy storage is currently increasing, especially from the perspectives of matching intermittent sources of renewable energy with customer demand and storing excess nuclear or thermal power during the daily cycle. Technologies to be considered for load leveling for large-scale energy systems, typically in the range of hours to days of discharge time, include pumped-storage hydr...
Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...
For a solar power plant, storing energy enables utilities to generate power when and as required and not just when sun is shining. There are two popular ways to convert solar energy to electricity – solar photovoltaic (PV) and solar thermal. In a solar PV plant sun’s energy is directly converted to electric energy using solar cells and therefore it requires a battery to store electric energy. A...
The demand for energy in the world has been growing rapidly [...]
The book contains 25 carefully selected papers covering new trends in energy storage systems. Internal combustion engine cars are planned to be sidelined by 2035 given that the European Commission recently imposed tougher CO2 emission reduction targets will effectively ban sales of diesel and gasoline vehicles beyond 2035. However, present- day electric (EVs) still give drivers some range charg...
Using the energy power supply concept, this paper proposes a DC voltage source with limited energy storage capacity, which models: the energy storage capacity of the batteries, the involved energy transfer process and the constant voltage output behavior when the battery has storage energy. Further, this circuit source is used for understanding the combined electrical circuitbased battery model...
Connection of electric storage technologies to smartgrids will have substantial implications for building energy systems. Local storage will enable demand response. When connected to buildings, mobile storage devices such as electric vehicles (EVs) are in competition with conventional stationary sources at the building. EVs can change the financial as well as environmental attractiveness of on-...
