This letter proposes discrete changes in the power output of emerging power technologies (EPT) for controlling oscillations and frequency excursions. For the former, a new perspective is proposed that connects oscillations with the transient shift of the system equilibrium point. This is transformative as discrete control can be applied to multi-modal systems for the first time, without any model aggregation. For the latter, new insights are provided in regard to the nature of the discrete actions. Applications to a 2-bus, 9-bus and 39-bus test systems are presented. Through the proposed scheme, EPT can be enabled with controls that recognize their characteristics, while expanding grid dynamic capabilities with the addition of new effective controllers.

寻求扩展的电网控制能力：对新兴电力技术的离散控制

这封信提出了新兴电力技术 (EPT) 的功率输出的离散变化，以控制振荡和频率偏移。对于前者，提出了一种新的观点，将振荡与系统平衡点的瞬态偏移联系起来。这是变革性的，因为离散控制可以首次应用于多模态系统，而无需任何模型聚合。对于后者，提供了关于离散动作的性质的新见解。介绍了 2 总线、9 总线和 39 总线测试系统的应用。通过所提出的方案，EPT 可以通过识别其特性的控制来启用，同时通过添加新的有效控制器来扩展电网动态能力。
