Photovoltaic (PV) power has a huge resource of supply, wide range of usage, and low impact on environment and it is considered as a key factor of the supply mix in the future for China. PV power is still in its infancy in China. It has higher cost than coal-fired power, and needs policy support....

This paper describes an approach to optimize the capacity of battery used in a grid-connected photovoltaic system (PV/storage system). Scheduling of the battery after installation has to be considered for the optimal design; because battery degradation cost is mainly a function of system...

The Recast of the EPBD (Energy Performance of Buildings) Directive from the 2010 introduced the definition of a “nearly zero energy building”, covering its energy needs from renewable sources. In energy efficient buildings the energy needs depend strongly on the running conditions. Thus,...

This paper presents an alternative design of wind turbine. Wind turbine design includes subsystem elements necessary to satisfy rigorous grid codes imposed by transmission system operators (TSOs). While the addition of these components assures compliance they have an impact on the overall...

Hydrogen is a kind of green fuel, and is considered as the substitute oil fuel for future. Although many of literature of photocatalyst water splitting have been presented, little of the literature focused on their energy conversions. Therefore, investigation of their energy conversions is...
