摘　　要：在电力市场和碳交易市场的背景下,为满足高比例新能源并网所带来的电力系统灵活性需求,且节省投资建设成本,提出一种考虑电碳耦合和灵活性供需平衡的源网荷储协同规划方法。首先,通过电价和碳交易价格建立电碳耦合关系;其次,对柔性负荷可调节潜能进行分析,根据电碳耦合下的自适应分时电价建立价格型需求响应模型;再次,分析电力系统中灵活性资源所具备的灵活性供给能力,建立灵活性供需平衡模型;然后,建立基于全生命周期理论的源网荷储协同规划双层模型,上层模型以电力系统建设投资的等年值综合成本最小为优化目标,下层模型以电力系统年运行成本与年碳交易成本之和最小为优化目标;最后,采用改进的自适应遗传算法对所建立的模型进行求解。算例结果验证了所提方法能够为源网荷储协同规划工作提供参考。In the context of the power and carbon trading markets,addressing the flexibility requirements of power systems with a high penetration of renewable energy while minimizing investments and construction costs is crucial.This paper proposes a collaborative planning method for source-grid-load-storage,incorporating electricity-carbon coupling and flexible supply-demand balance.First,the electricity-carbon coupling relationship is established by considering electricity prices and carbon trading prices.Second,the adjustable potential of flexible load is analyzed,and a price-based demand response model is developed based on adaptive time-sharing tariffs under electricity-carbon coupling.Third,the flexibility supply capacity of various resources within the power system is assessed,leading to the formulation of a flexibility supply-demand equilibrium model.This model is further refined using a full life-cycle theory.Subsequently,a two-layer source-grid-load-storage cooperative planning model is proposed,with the upper layer aimed at minimizing the integrated cost of construction investment using the equal annual value method,while the lower layer seeks to minimize the sum of the annual operational cost of the power system and the annual carbon trading cost.Finally,the improved adaptive genetic algorithm is used to solve the model.The case study results demonstrate that the proposed method provides a valuable reference for the collaborative planning of source-grid-load-storage systems.
