In the dynamic landscape of energy transition, researchers from Sichuan University are making waves with a novel approach to modeling the future of flexible power generation units. As the world pivots towards renewable energy to meet “carbon peaking” and “carbon neutrality” goals, the stability of power grids is under scrutiny. Enter the work of LI Kecun and his team at the College of Electrical Engineering, Sichuan University, who have developed a dual-timescale dynamic model that could revolutionize how we understand and optimize flexible gas units and energy storage systems.
The study, published in ‘Dianli jianshe’ (Power System Engineering), addresses a critical gap in the current market: the lack of clear self-profit development trends for flexible units. Traditional models often fall short in accurately capturing the intricacies of electricity price generation processes. LI Kecun explains, “Our model combines system dynamics with spot market clearing, providing a more realistic simulation of electricity price scenarios and the resulting self-profit growth trends for flexible units.”
The dual-timescale dynamic model introduced by the team integrates a spot market-clearing model based on unit commitment optimization. This integration allows for a more precise validation of operational constraints and calculation of spot market-clearing results. “By simulating different subsidy schemes, we can provide valuable insights for power system planners and policymakers,” says LI Kecun.
The implications of this research are profound. As the energy sector grapples with the transition from traditional to renewable energy sources, the stability of the power grid remains a paramount concern. The model developed by LI Kecun and his team offers a robust framework for simulating and optimizing the investment and development of various power generation types, including flexible gas units and energy storage systems.
This research is poised to shape future developments in the energy sector by offering a more comprehensive understanding of market dynamics and operational constraints. As the electricity market continues to evolve, the insights gained from this dual-timescale dynamic model could pave the way for more efficient and sustainable power generation strategies. The study not only highlights the importance of flexible units in maintaining grid stability but also provides a roadmap for policymakers and industry leaders to navigate the complexities of the energy transition.
