摘要

现代电力系统“双高”特性明显，抗扰动能力弱，调频能力不足，亟须负荷侧的主动支撑能力，轨道交通负荷拥有潜在的“短时高功率”调节特性。该文首先建立面向系统频率支撑的列车微分动力学模型及运行控制约束；然后，构建离散-解析混合驱动的列车运行轨迹在线更新模型并考虑不同输入特征的轨迹跟踪控制方法；在此基础上，阐述单列车可控灵活性度量指标和多列车协同调频容量估计方法；最后，将列车主动支撑控制理论和方法应用于电力系统频率控制，证明轨道交通负荷支撑电力系统频率调控的可行性和有效性。

Abstract

Modern power systems are characterized by high penetration of renewable energy sources and power electronic equipment

with insufficient frequency control capacity. Grid support from the load side is urgently needed. Electrified rail transportation possesses potential grid support capability with high power level in a short period. In this paper

the differential dynamical model and operating constraints of rail transportation are established for system frequency support. The discrete-analytical hybrid-driven trajectory optimization method and the trajectory tracking control method considering different input characteristics are constructed. The single-train controllable flexibility and the multi-train coordinated grid support capacity are evaluated. Finally

the T2G (train-to-grid) support model

theory

and method are applied to varies system frequency control scenes

validating the feasibility and effectiveness of the presented T2G frequency support theory and method.
