Description

Technical Field

[0002] As renewable energy becomes increasingly prominent in the energy mix, teaching and training platforms for solar energy, wind energy, and power supply and distribution technologies are gaining increasing attention. These platforms aim to provide students and researchers with a platform for practice and research, helping them better understand and master these key technologies.

[0003] The existing teaching and training platforms still have shortcomings in some aspects, which are mainly reflected in the following aspects: First, traditional light energy teaching and training platforms often only focus on the basic principles and equipment operation of photovoltaic power generation, and lack simulation and optimization of light energy conversion efficiency and the influence of environmental factors. This makes it difficult for students to gain a comprehensive understanding and experience in actual operations. Secondly, wind energy teaching and training platforms usually only focus on the working principles and basic operations of wind turbines, and there are relatively few simulations and practices in aspects such as wind energy utilization efficiency and wind field planning. This limits students' comprehensive understanding and application capabilities of wind energy technology. In addition, power supply and distribution training platforms often only focus on the basic operations and equipment management of distribution networks, and lack the practice and simulation of emerging technologies such as smart grids and distributed energy. This makes it difficult for students to quickly adapt to and respond to new technological challenges in their future work;

Therefore, it is necessary to develop a new teaching and training platform that includes solar energy, wind energy, energy storage, and power supply and distribution technologies to provide a more comprehensive and in-depth practice and learning environment.
