在电气岛上，频率偏移相当大，并且通常需要自动减载以响应干扰。此外，风能和太阳能发电厂通常不提供惯性响应，取代传统发电进一步削弱了这些电力系统。快速储能系统可以在发电机组故障后立即注入电力，从而在激活其主要储备期间为传统发电资产提供备份。本文依靠动态模拟来研究风能或太阳能发电占比较大的法国瓜德罗普岛的储能系统提供这种动态频率控制支持的情况。结果表明，快速储能通过充当合成惯性，可以减轻这些源在发生重大发电中断的情况下对所研究的岛屿电网动态性能的影响。可再生能源提出的其他问题（例如，可变性、预测准确性、低电压穿越等）尚未在该项目中得到解决。
In electrical islands, frequency excursions are sizeable and automatic load shedding is often required in response to disturbances. Moreover, the displacement of conventional generation with wind and solar plants, which usually do not provide inertial response, further weakens these power systems. Fast-acting storage, by injecting power within instants after the loss of a generating unit, can back up conventional generation assets during the activation of their primary reserve. This paper relies on dynamic simulations to study the provision of such a dynamic frequency control support by energy storage systems in the French island of Guadeloupe with large shares of wind or solar generation. The results show that fast-acting storage, by acting as a synthetic inertia, can mitigate the impact of these sources on the dynamic performance of the studied island grid in the case of a major generation outage. The other concerns raised by renewables (e.g., variability, forecast accuracy, low voltage ride-through, etc.) have not been addressed within this project.
