Abstract
This paper proposes a control scheme that computes the maximum available power capacity for a charging site (CS) in real time without causing voltage or congestion issues in the distribution grid. The controller uses a measured variable consisting of one or multiple local measurements near or at the CS. As a result, the proposed control scheme can operate autonomously without the need for a central controller. A three-step method is developed to evaluate and select different measurements with their setpoints for the controller. Finally, a case study of a distribution grid is used to demonstrate the measurement selection method and to simulate the controller. Results show that the proposed framework can achieve near-optimal performance despite only relying on local measurements.
