Analysis of the Characteristics and Applications of Wind-Solar-Storage Systems in the Smart Grid

Abstract

At present, with the rapid development of smart grid, scenery storage system, as the core carrier of multi-energy complementarity, has shown significant advantages in improving the energy absorption capacity of renewable energy, enhancing the flexibility and stability of power grid. However, the intermittent and uncertainty of renewable energy generation poses many challenges to the grid operation. This paper takes wind energy, photovoltaic and energy storage as the basic entry point, combines the actual situation, extends the overall architecture of the landscape storage smart grid and analyzes the architecture. Then, the key technologies of the wind light storage system under the background of the smart grid are systematically analyzed. For example, the characteristics and application progress of technologies such as renewable energy grid, energy storage, demand side response, virtual power plant and other technologies, although these technologies have been successful, some problems remain. At the end of this paper, the research bottlenecks, optimizable items and prospects for the future are also discussed.
