On the search for expanded grid control capabilities: Discrete control on emerging power technologies
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
