In the dynamic landscape of the energy sector, the pursuit of carbon neutrality has sparked innovative collaborations among power generation entities. A groundbreaking study led by DUAN Shaowei, CAI Ye, TANG Xiafei, TANG Liang, and TAN Yudong from the State Key Laboratory of Disaster Prevention & Reduction for Power Grid at Changsha University of Science and Technology, and the Economic and Technical Research Institute of State Grid Hunan Electric Power Co., Ltd., has shed light on the complex interplay between pumped storage stations, wind power stations, and photovoltaic power stations. This research, published in ‘Dianli jianshe’ (Electric Power Construction), delves into the formation and stability of cooperative alliances driven by the shared goal of achieving carbon peak and carbon neutrality.
The study introduces a novel approach to understanding the long-term stability of these alliances through evolutionary game theory. Unlike traditional game theory methods, which often assume complete rationality, this approach acknowledges the inherent complexity and randomness of the game process. By constructing a benefit coordination model and optimizing the output of each entity, the researchers have revealed the mechanisms behind the formation and potential breakdown of these cooperative alliances.
The findings are both intriguing and practical. The research suggests that pumped storage stations can play a pivotal role in future cooperative alliances, acting as stabilizing entities that ensure the consumption of new energy. “Pumped storage stations can act as a buffer, absorbing excess energy from wind and solar sources during peak production times and releasing it when demand is high,” explains DUAN Shaowei, the lead author. This dynamic not only enhances the reliability of the power grid but also maximizes the utilization of renewable energy sources, a critical factor in achieving carbon neutrality.
The study further identifies three distinct stages in the evolution of these alliances: the initial stage, the development stage, and the rupture stage. These stages are characterized by the proportion of new energy installed capacity. Interestingly, the research highlights the potential for solar power stations to withdraw from the alliance prematurely due to random interference factors, underscoring the need for robust risk management strategies.
The implications of this research are far-reaching. For power grid companies, the insights provide a roadmap for maintaining the stability of cooperative alliances, ensuring a more resilient and efficient energy system. “Our findings offer a theoretical framework for power grid companies to navigate the complexities of multi-agent cooperation,” says CAI Ye, a co-author of the study. “By understanding the dynamics of these alliances, companies can better plan for the integration of renewable energy sources and ensure a stable power supply.”
As the energy sector continues to evolve, the research by DUAN Shaowei and his team offers a compelling vision of a future where pumped storage stations, wind power stations, and photovoltaic power stations work in harmony. This collaborative approach not only supports the transition to cleaner energy sources but also paves the way for a more sustainable and resilient power grid. The study, published in ‘Dianli jianshe’ (Electric Power Construction), marks a significant step forward in the quest for carbon neutrality and underscores the importance of innovative research in shaping the future of the energy sector.
