Preemptive control: A paradigm in supporting high renewable penetration levels

Abstract

This paper investigates a preemptive approach to cope with solar induced grid voltage intermittencies. To do so, this paper proposes a combination of a predictor and a voltage controller to eliminate the delays associated with conventional sample based voltage regulation. Unlike model predictive controllers, the proposed preemptive approach focuses on the input disturbances and does not neglect them as zero mean wiener processes. Additionally, due to the utilization of input predictors, the controller is no longer bound to causal response to the sampled data and can preemptively compensate for upcoming events. After introducing the proposed controller, simulation results are provided to compare the effectiveness of this approach in comparison with the existing voltage regulator schemes.
