Proactive Sequential Phase Swapping Scheduling for Power Distribution Systems with a Finite Horizon

A phase swapping system is provided for swapping phases in a power distribution system. The system includes an interface circuitry configured to receive, from sensors arranged at buses in the power distribution system, real-time states at current time step, wherein each of the real-time states are associated with a complex power flowing from an upstream bus to a downstream bus, one or more processors and a non-transitory computer-readable storage medium having stored thereon executable instructions that, when executed by the one or more processors, cause the phase swapping system to perform steps of determining a multi-step phase swapping action by using the real-time states and a trained optimal policy generating phase swapping commands based on the multi-step phase swapping action, and transmitting, via the interface circuitry, the phase swapping commands to phase swapping devices arranged at around the sensors, wherein the phase swapping devices are configured to perform the multi-step phase swapping action based on the phase swapping commands.
