Abstract

An energy system includes a microgrid including a network of at least one distributed energy resource and a plurality of loads, the at least one distributed energy resource being configured to supply power to the plurality of loads. The microgrid is configurable to connect to one of a plurality of feeder circuits of a main power grid at one of a plurality of coupling interface locations, respectively. The microgrid is also configurable to expand or shrink its power supply area according to the available power generation capabilities.

Method and apparatus for identifying, locating and quantifying physical phenomena and structure including same

Patent Richardson, John G.

A method and system for detecting, locating and quantifying a physical phenomena such as strain or a deformation in a structure. A minimum resolvable distance along the structure is selected and a quantity of laterally adjacent conductors is determined. Each conductor includes a plurality of segments coupled in series which define the minimum resolvable distance along the structure. When a deformation occurs, changes in the defined energy transmission characteristics along each conductor are compared to determine which segment contains the deformation.

Engine system and method of operating same over multiple engine load ranges

Patent Duffy, Kevin P.; Urven, Jr., Roger L.; Brown, Cory A.; ...

A method of operating an engine system should produce relatively low concentrations of various emissions without compromising a desired power output of the system. In order to operate an engine system of the present disclosure, a predetermined total amount of fuel injected into at least one combustion chamber is apportioned into at least a first amount and a second amount of fuel. The first amount of fuel is injected into the at least one combustion chamber during non-auto ignition conditions. The second amount of fuel is injected into the at least one combustion chamber during auto-ignition conditions. When the enginemore »« less
