As the global energy landscape shifts towards sustainability, a new study offers a transformative approach to managing energy storage in power systems. Researchers led by Chao Xing at the Electric Power Research Institute of Yunnan Power Grid Co., Ltd. have unveiled a two-layer optimal scheduling model that integrates composite energy storage with thermal power, addressing the critical challenges posed by the increasing uncertainty in renewable energy sources like wind and solar.
The study, published in the journal ‘Energies’, highlights the pressing need for effective peak regulation strategies as renewable energy generation surges. “The rise in new energy capacity complicates peak regulation, making it essential to find innovative solutions,” explains Xing. This research proposes a model that not only enhances the economic viability of thermal power generation but also optimizes the performance of energy storage systems, particularly in managing the fluctuations caused by renewable sources.
At the heart of this research lies a dual-layer scheduling framework. The upper layer focuses on minimizing net load fluctuations through pumped storage, while the lower layer aims to reduce the overall peak load costs. By employing an improved gray wolf algorithm, the model processes these complexities to create a day-ahead scheduling plan that can significantly enhance the operational efficiency of power systems.
The implications of this research extend beyond theoretical advancements; they hold substantial commercial potential for the energy sector. By improving the coordination between thermal power and composite energy storage, utilities can better manage costs associated with peak load demand, ultimately leading to lower energy prices for consumers and higher profitability for energy providers. “Our findings suggest that a balanced approach to energy storage can yield better economic outcomes for the entire system,” Xing notes.
Moreover, the study underscores the importance of adaptability in energy systems. As the capacity of pumped storage reaches its limits, the research indicates that enhancing the deep peak regulation capabilities of thermal power units, alongside the development of battery storage, can unlock new peak regulation resources. This adaptability is crucial as the energy market continues to evolve, driven by regulatory changes and technological advancements.
In a world increasingly focused on carbon neutrality, the findings from this study could pave the way for more efficient and economically sustainable energy systems. The integration of advanced scheduling models not only addresses current challenges but also sets the stage for future innovations in energy management.
