Abstract
Present wind power is intermittent and cannot be used as the baseload energy source. Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage named Wind powered Thermal Energy System (WTES) is conducted. The thermal energy is generated from the rotating energy directly at the top of the tower by the heat generator, which is a kind of simple and light electric brake. The rest of the system is the same as the tower type concentrated solar power (CSP). The cost estimation suggests that the energy cost of WTES is less than that of the conventional wind power, which must be supported by the backup thermal plants and grid enhancement. The light heat generator reduces some issues of wind power such as noise and vibration.
Highlights
Considerable amount of installation of the renewable energies to the power network arises lots of issues since the most of the renewable energies are intermittent [1]
This paper describes a novel idea named wind heat power (WTES), which is proposed for the first time, to solve the network issues
The use of energy storage is studied from various aspects [7,8]. Utilization of this thermal energy storage and employment of light and low cost heat generator are the key points of Wind powered Thermal Energy System (WTES)
Summary
Considerable amount of installation of the renewable energies to the power network arises lots of issues since the most of the renewable energies are intermittent [1]. This paper describes a novel idea named wind heat power (WTES), which is proposed for the first time, to solve the network issues. The sum of the thermal energy storage will become almost double in 2015 [3]. The use of energy storage is studied from various aspects [7,8]. Utilization of this thermal energy storage and employment of light and low cost heat generator are the key points of WTES. The present situation of the renewable energies' installation conditions in various regions is analyzed and the merit of WTES is described in this paper
