Fuel efficiency optimization for microgrid systems employing multiple generators

摘要

A system designed to optimize fuel efficiency of a power grid includes a set of controllable generators designed to supply power to the power grid. Each generator in the set is associated with a controller, a set of loads designed to draw power from the power grid, and a grid controller designed to provide a load partitioned configuration for the set of controllable generators, based at least partly on the power draw of the set of loads.

1. A system designed to optimize fuel efficiency of a power grid, the system comprising:
a set of controllable generators designed to supply power to the power grid, each generator in the set being associated with a controller; a set of loads designed to draw power from the power grid; a set of data, control and power distribution components connecting the various system elements and subsystems; and a microgrid control system including a single system controller communicating with each of said controllers and designed to analyze and control generator engine torques on a system wide basis, based at least partly on microgrid monitored system loading and to manage system operation and specifically to provide a continuously variable load assignment capability for the set of controllable generators based at least partly on the power requirements of the set of loads; wherein the system controller is configured to invoke a gain scheduler to change a control loop gain when a load share is determined to be unstable thereby making the power grid a self-configuring, auto-tuning grid.
