In a significant advancement for the energy sector, researchers from Shanghai Jiao Tong University have unveiled a novel coordination strategy aimed at mitigating power fluctuations within combined heating and power integrated energy systems (CMPIES). This innovative approach utilizes a virtual energy storage system, leveraging the thermal properties of buildings to stabilize energy output and enhance the operational flexibility of distributed generation resources.
Erjia Zhang, the lead author of the study, emphasizes the importance of this research in addressing the challenges posed by fluctuating energy sources. “Our strategy not only smooths the tie-line power fluctuations but also ensures that the comfort of customers is maintained while enhancing the overall efficiency of the energy system,” Zhang stated. This dual focus on reliability and customer satisfaction could have profound implications for how energy systems are designed and operated in the future.
The research meticulously analyzed the structure and energy coupling modes of CMPIES, which include a variety of controllable devices such as micro-gas turbines, heat pumps, batteries, and supercapacitors. By employing a weighted moving average filtering algorithm, the team optimized the reference power for tie-line operations. The strategy also incorporates a state map table that dynamically adjusts filter time constants based on real-time operational conditions, allowing for a responsive and adaptive energy management system.
The validation of this strategy through field data collected at the Green Energy University Laboratory in China showcases its practical applicability. The simulation results indicate that this coordination strategy not only smooths power fluctuations but also facilitates better integration of renewable energy sources, potentially increasing their penetration in the market. This could lead to a more resilient and sustainable energy grid, crucial for meeting global energy demands while minimizing environmental impact.
Zhang’s work points to a future where energy systems are not just reactive but proactive, adapting to fluctuations in supply and demand with greater agility. “By enhancing the controllability of devices and utilizing virtual energy storage, we can significantly prolong the lifespan of these resources while maximizing their output,” he added. This perspective aligns with the growing trend of integrating advanced technologies into energy systems, signaling a shift towards smarter, more efficient energy management practices.
As the energy sector continues to evolve, the implications of this research extend beyond technical advancements. By improving the efficiency and reliability of energy systems, it paves the way for increased investment in renewable energy technologies, potentially transforming the landscape of energy generation and consumption.
