摘要

煤电是传统的灵活性资源，在由基础保障性电源向系统调节性电源的转型过程中，需统筹好新建、在役和到龄煤电机组的关系，以解决灵活性不足导致的电力供应不足或者新能源消纳难题。因此，该文提出典型与极端场景下考虑煤电机组转型的灵活性资源协同规划方法，实现多场景下的灵活性提升。文中建立包含在役煤电机组灵活性改造、到龄煤电机组退役、延寿、转应急备用的煤电转型模型，并嵌入源网荷储多元灵活性资源的调节能力及成本模型中；以煤电转型路径、其他灵活性资源建设为决策变量，提出源网荷储灵活性资源协同规划模型；基于权重实现典型与极端多场景的结合，迭代投资决策与日前日内运行优化2个子模型实现有效求解；最后，以改进的IEEE 24节点系统为例，分析多场景下灵活性不足问题的时空特性，实现电力系统灵活性与经济性的协同提升。

Abstract

Coal power is a traditional flexible resource. In the process of transformation from basic guarantee power to system regulation power

it is necessary to coordinate the relationship between new

in-service and ageing coal power units to solve the problem of insufficient power supply or new energy consumption caused by insufficient flexibility. Therefore

a collaborative planning method of flexible resources considering the transformation of coal-fired power units in typical and extreme scenarios is proposed

which realizes the improvement of flexibility in multi-scenarios. In this paper

a coal-fired power transformation model including flexibility transformation of in-service coal-fired power units

retirement

life extension and emergency reserve of ageing coal-fired power units is established and embedded in the adjustment ability and cost model of source-grid-load-storage resources. Taking the transition path of coal power and the construction of other flexibility resources as decision variables

a collaborative planning model for source-grid-load-storage flexibility resources is proposed

which is based on the weights to realize the combination of typical and extreme multi-scenarios

and the two sub-models of iterative investment decision along with day-ahead intra-day operation optimization to realize an effective solution. Finally

taking the improved IEEE 24-bus system as an example

the spatial and temporal characteristics of the problem of insufficient flexibility in multi-scenarios are analyzed

and a collaborative increase in power system flexibility and economics is realized.
