Cost-Effectiveness Analysis of Solar and Wind Power Generation in Microgrid Systems: A Case Study of Changbin Industrial Zone

The study centers on a comprehensive cost-effectiveness analysis of solar and wind power generation within the microgrid system located in the Changbin Industrial Zone. This region, characterized by favorable solar irradiance and wind conditions, is an ideal location for developing and implementing renewable energy systems. Through extensive simulations, we examined the impact of temperature fluctuations on photovoltaic (PV) module efficiency and the influence of varying wind turbine heights on energy output. Our findings revealed that temperature plays a crucial role in determining the performance of PV modules, with higher temperatures leading to a noticeable decline in efficiency. Conversely, wind power generation is significantly affected by the height of wind turbines, where increased height results in enhanced energy capture due to stronger and more consistent wind speeds at elevated altitudes. Furthermore, the study underscores the importance of considering seasonal variations, as these can significantly influence the overall efficiency and reliability of renewable energy systems within a microgrid. By optimizing wind turbine heights and incorporating strategies to mitigate the effects of temperature fluctuations on solar panels, the study demonstrates that it is possible to significantly improve the overall power generation efficiency of the microgrid system. Improving efficiency reduces the cost per kilowatt-hour of electricity generated, thereby enhancing the economic viability of renewable energy projects. The insights gained from this analysis are expected to provide valuable guidance for future renewable energy planning, particularly in regions with similar climatic and geographical conditions. Such strategic planning is essential for maximizing the return on investment and ensuring the long-term sustainability of renewable energy systems.
