  • Patent number: 7860702
    Abstract: An improved method for analyzing power systems; in particular, power systems that may incorporate distributed energy resources (DER), that provides a thorough determination of the potential for network performance improvement that DER could provide, independent of non-network benefits DER could provide. The method incorporates an Energynet dataset simulating the power system, integrating transmission and distribution elements together and capable of evaluating the impacts of additions of real energy sources and/or reactive energy sources anywhere in the network. Such energy source additions are evaluated for their impact on a broad set of performance measures. The specific DER projects that would realize that potential improvement in network performance are characterized as an Optimal DER Portfolio. Network performance improvement attributable to the Optimal DER Portfolio is quantified in engineering and financial terms.
    Type: Grant

  • Patent number: 4763005
    Abstract: An improved method and apparatus for bombarding an object with charged particles. A shaping magnet is provided to spread the beam of charged particles emitted by a charged particle gun after the beam has left the gun. The beam is shaped so that it will completely envelope the object and provide substantially uniform penetration. The shaping of the electron beam is done after the beam has left the electron gun, unlike the prior art devices which shape the beam in the gun to produce a focusing effect. This provides more control over the shape of the beam.
