Study on Operation Technology of Wind-PV-Energy Storage Combined Power Generation

Abstract

With the increasing demand for energy and the rapid development of new energy, the technology of generating electricity by wind and solar energy has gradually matured, and the penetration rate in the power grid is also increasing. In order to remedy problems of unstable power and low power quality caused by wind and solar power generation, it is necessary to study the combined power generation of wind power, solar energy and energy storage. In this paper, the strategy of energy storage inhibition control is summarized according to the simple suppression method, the suppression method considering certain constraints, the suppression method considering power prediction and artificial intelligence. In the study of energy storage to tame scenery fluctuation filtering algorithm is the most common method, adding certain constraints can make smooth effect better, and energy storage to tame with accurate prediction can make the system smoother. Multi-energy storage technology can give full play to the advantages of energy storage technology. The wind energy storage complementary system with the energy storage device can effectively reduce the adverse effect of the original wind energy complementary system on the power grid. It can smooth the output characteristics of the wind power generation system to a higher degree, increase the acceptance of renewable energy to the power grid, and achieve good economic and social benefits.
