Review of energy harvesting technologies and applications in smart grid

Abstract

The demand for power sensors is growing rapidly, and the demand for energy supply is becoming more and more obvious. The disadvantages of the traditional single-battery power supply scheme are becoming more and more obvious. At the same time, with the development of kinetic energy, temperature difference, photovoltaic, electromagnetic and other energy collection technologies and integrated circuit technologies, new ideas are put forward for the energy supply of power sensors. Promoting energy harvesting technology and power sensor coupling in smart grids can improve social benefits and form a win-win situation for all parties. This paper firstly analyzes the urgent demand of smart grid for energy harvesting technology. Secondly, the development status of energy harvesting technology and related integrated circuits is analyzed. Finally, according to the shortcomings of energy harvesting technology in smart grid, the research direction of energy harvesting technology suitable for smart grid is proposed.
