煤电机组耦合储能灵活性调峰技术研究进展OA

Against the backdrop of energy transition,the installed capacity of renewable energy sources has been steadily increasing,which leads to a substantial widening of the peak-valley load gap in power systems.Concurrently,the demand for enhancing stability and flexibility in power supply systems continues to escalate.Under these circumstances,the integration of(coal-fired power plants)CFPP with energy storage systems(ESS)to participate in peak shaving has emerged as an imperative technological trajectory for the power industry.A comprehensive analysis of CFPP-ESS coupling systems is conducted,focusing on the key technical advancements and practical challenges.A systematic review of state-of-the-art energy storage technologies—including pumped hydro storage,electrochemical energy storage,and compressed air energy storage—is presented,with detailed discussions on their operational principles and application-specific performance metrics.The operational status of CFPP-ESS coupling systems is investigated through a multi-dimensional framework,encompassing technical implementation strategies,dynamic response characteristics and real-world performance evaluations.Critical challenges—including techno-economic compatibility,cost-benefit trade-offs,and market mechanism adaptability—are rigorously examined.Based on these findings,a suite of solutions is proposed to address technical bottlenecks and optimize economic viability.The outcomes of this research are expected to offer actionable insights for optimizing operational strategies and informing policy-making frameworks,thereby accelerating the sustainable deployment of CFPP-ESS hybrid systems in modern power grids.
