In a groundbreaking study published in ‘Sustainable Energy Research’, researchers have unveiled an innovative approach to optimizing photovoltaic storage capacity in rural new energy microgrids. Led by Huixuan Li from the Economic and Technical Research Institute at State Grid Henan Electric Power Co., Ltd., the research addresses the pressing issues of low energy efficiency and unstable operations that have long plagued these systems.
The study introduces a two-layer multi-objective collaborative decision-making framework, which is a significant advancement for rural energy infrastructures. By constructing both outer and inner optimization objective functions, the researchers tackled various constraints, including capacity allocation, transmission security, and energy storage self-discharge correction. This dual-layer approach not only enhances the operational reliability of microgrids but also ensures that energy is utilized more efficiently.
“The optimization method we’ve developed allows for a more nuanced understanding of how to allocate resources in microgrids,” Li explains. “By balancing multiple objectives, we can significantly reduce energy consumption and improve overall reliability, which is crucial for rural communities that often face energy shortages.”
The results of the study are promising, showcasing a remarkable reduction in total energy consumption, power deviation rates, and load loss costs. Specifically, the research noted maximum reductions of up to 90.5% in energy consumption and 114,700 yuan in load loss costs. Moreover, the load loss probability was kept below 2.2%, demonstrating a robust performance across various lighting and load demand scenarios.
This research not only provides a technical solution but also holds substantial commercial implications for the energy sector. As rural areas increasingly turn to renewable energy sources, the ability to optimize storage capacity can lead to more sustainable and economically viable energy solutions. With the global push towards greener energy, this study could serve as a blueprint for future developments in microgrid technology.
Li’s work represents a critical step forward in addressing the unique challenges faced by rural energy systems. As microgrids become more prevalent, the methodologies developed in this research will likely influence how energy providers approach the integration of renewable sources. The potential for improved energy efficiency and reliability could reshape the landscape of rural energy, making it a vital area of focus for both researchers and commercial entities alike.
