由可再生能源集成驱动的系统惯性减小对一次频率控制提出了重大挑战。道路运输电气化不仅通过从化石燃料消费转向更清洁的电力消费来减少碳排放，而且还可能提供灵活性，以促进可再生能源的整合，例如支持一次频率控制。在此背景下，本文开发了一个技术经济评估框架，以量化一次频率控制的挑战，并评估电动汽车在提供一次频率响应方面的好处。采用简化的GB电力系统动态模型，分析了系统惯性下降对一次频率控制的影响以及电动汽车提供一次频率响应的技术潜力。此外，一个先进的随机系统调度工具，明确建模的惯性降低效果，以评估成本和排放驱动的一次频率控制，以及电动汽车在提供一次频率响应下的两个代表性的GB 2030系统场景的好处。本文还确定了电动汽车提供的PFR和“智能充电”策略之间的协同作用，以及风力涡轮机的合成惯性的影响。
System inertia reduction, driven by the integration of renewables, imposes significant challenges on the primary frequency control. Electrification of road transport not only reduces carbon emission by shifting from fossil fuel consumption to cleaner electricity consumption, but also potentially provide flexibility to facilitate the integration of renewables, such as supporting primary frequency control. In this context, this paper develops a techno-economic evaluation framework to quantify the challenges on primary frequency control and assess the benefits of EVs in providing primary frequency response. A simplified GB power system dynamic model is used to analyze the impact of declining system inertia on the primary frequency control and the technical potential of primary frequency response provision from EVs. Furthermore, an advanced stochastic system scheduling tool with explicitly modeling of inertia reduction effect is applied to assess the cost and emission driven by primary frequency control as well as the benefits of EVs in providing primary frequency response under two representative GB 2030 system scenarios. This paper also identifies the synergy between PFR provision from EVs and “smart charging” strategy as well as the impact of synthetic inertia from wind turbines.
