From Grid Connection to Grid Construction: Technologies and Scenarios of Wind-Solar-Storage Smart Grid Systems

Abstract

This essay takes the wind-solar-storage smart grid system as the research object and systematically analyzes its current development status, core technologies, energy storage optimization configuration algorithms and multiple application scenarios. The study points out that the current system is transitioning from “grid connection” to “grid construction”, with core technologies focusing on grid-construction control, intelligent prediction, multi-energy storage integration and the integration of smart grid characteristics. The article focuses on comparing and analyzing the performance of the dung beetle algorithm, the white shark algorithm and the gray wolf algorithm in solving the problem of optimal allocation of energy storage capacity, and discusses their effects in improving the economy and reliability of the system. The study further explored the application models and value of the system in typical scenarios such as large-scale base transmission, distributed microgrids, and power supply for critical loads. This paper aims to provide systematic theoretical references for the planning, design and operation of wind-solar-storage smart grid systems through an integrated analysis of technical paths, optimization methods and application practices.
