Abstract: A power quality compensation system and a power quality compensation method are provided. The power quality compensation apparatus includes an input filter, a power electronic converter, a controller configured to control the power electronic converter, and a plurality of inductors connected to the power electronic converter. The power quality compensation method includes receiving signals from one or more sensors configured to detect voltage and current from an input side and an output side of the power quality compensation system, calculating reference signals, and using model predictive control to track the reference signals.

Abstract: A method for determining a control architecture for a network of protective relays of a power distribution system. The method includes receiving data specifying a topology of a plurality of relays in the network of protective relays. The method includes sequentially modelling each relay in the network of protective relays using a reinforcement learning algorithm, including modelling each relay as an agent configured to detect one or more local conditions on the power distribution system and configured to trip based on the one or more local conditions. The method includes determining, based on the sequential modelling, one or more control parameters for each relay in the network of protective relays.
