Abstract

Our system improves the efficiency and functionality of a grid-interactive or grid-tied power system that utilizes one or more local power sources and one or more local energy storage devices. The purpose is the coordination, optimization and efficient control, regulation, and transfer of electrical energy among several energy storage devices, power generators, the utility grid, and connected local electrical loads. The coordinated control and utilization of local storage and generation combined with coordinated integration with the utility grid results in an overall system that can be more flexible, economical, and efficient than any of the individual components can be, when operated separately. It uses dynamic adjustment, feedback, and other control modules/methods.
