Development of Hybrid Generation Technology Learning Devices in Electrical Engineering Education

The increasing complexity of renewable energy systems and hybrid generation technologies requires innovative educational approaches to prepare electrical engineering students for modern power system challenges. This study presents the development and evaluation of a hybrid generation technology learning device that integrates photovoltaic, wind turbine, battery storage, and grid connection components within a single educational platform. The system achieved 87% photovoltaic efficiency and 82% wind generation efficiency with measurement accuracy within ±3%. Educational effectiveness was evaluated through a controlled study involving 120 students across three institutions. Results demonstrated significant improvements in learning outcomes, with experimental group students achieving 20.4% higher post-test scores compared to control groups (p < 0.001, Cohen's d = 1.24). Knowledge retention testing after six weeks showed sustained advantages (74.1% vs 58.9%). Students exhibited 40% more conceptual connections and enhanced practical skills development. Cost-effectiveness analysis revealed 44% lower ownership costs compared to commercial alternatives. The learning device successfully addresses gaps in existing educational resources while providing economically viable solutions for widespread institutional adoption in electrical engineering programs.
