Abstract

This paper presents a planning method for micro energy networks, integrating renewable energy sources such as photovoltaic, wind energy, combined heat and power systems, and energy storage. The proposed optimization approach is developed to minimize operational costs by implementing dynamic operation strategies. Through a variable-step search space method, the optimal power output for each generation unit within the system is determined. The results demonstrate that the model can effectively maintain energy balance throughout different seasons while optimizing operational costs. The study also clarifies the impact of time-based electricity pricing on system performance. Furthermore, it highlights the importance of integrating renewable energy sources into microgrids to enhance sustainability and energy efficiency. The proposed method ensures flexibility and reliability of the operational model under varying load and weather conditions. Overall, this study contributes to advancing renewable energy planning, improving cost efficiency, and developing environmentally friendly energy solutions for future energy systems.
