Abstract: The disclosed system provides an adaptive control system technique generally related to distributed energy resources (DERs) located in distribution circuits. More specifically, the system technique relates to a DER with both active and reactive generation capability. In an embodiment, the system measures a voltage phase angle and a current phase angle of distribution feeder circuit, and measures a voltage value output by a power converter. The system calculates an active power setpoint value and a reactive power setpoint value of the power converter based on the measured voltage value, and the measured voltage phase angle and current phase angle. The system then sets the active and reactive power setpoint values on the power converter. The disclosed system automatically adjusts the setpoints to real-time load characteristics of the distribution feeder circuit, increases distribution feeder hosting capacity, and enables DERs to integrate in distribution feeders more efficiently.

Abstract: An apparatus and method efficiently integrating inductive and conductive charging systems, including embodiments directed towards enabling user selection of either, or both, of conductive and inductive charging. Conductive charging and inductive charging both have, in certain contexts or when judged by different criteria, advantages over the other. Systems and methods relying on one or the other would not have as wide-spread value to a user with opportunities to access both types of charging modalities.
