With the acceleration of energy transition, the application of renewable energy in electrical engineering is becoming increasingly widespread. However, its utilization efficiency still faces many challenges. This paper analyzes the current status of renewable energy application and points out problems such as intermittency, insufficient energy storage technology, difficulties in grid connection, and incomplete technical standards. In response to these issues, it proposes technical measures such as optimizing energy storage systems, developing smart grids, promoting multi - energy complementarity, and improving technical standards, and discusses the practical application effects and cases of these measures. The research results show that, through technological innovation and policy support, the utilization efficiency of renewable energy can be significantly improved, providing strong support for achieving sustainable development goals.
