Abstract: A power facility has at least one power element and a system monitors/controls at least a portion of the power facility. In the system, a field drop is coupled to each element for monitoring same, reporting status data, receiving control information, and controlling such element. A local area network (LAN) couples each field drop to a hub, and a data server is coupled to the hub. The data server receives the status data from each field drop and takes any appropriate action necessary in response thereto, and also allows a user to access any particular field drop of the system to read data for the corresponding element and issue control commands for the element to be carried out by the corresponding field drop.

Abstract: An electronic interface couples a combination of generation and storage devices with a power grid and/or a load. The interface comprises a DC bus; a DC storage device coupled to the DC bus; a first DC-to-AC inverter (N1) having a DC port operatively coupled to the DC bus, and an AC port; a second DC-to-AC inverter (N2) having a DC port operatively coupled to the DC bus, and an AC port; a switch (S4) for electrically coupling the AC port of the second DC-to-AC inverter to a first generator or an AC storage device; a first rectifier (D1) for coupling an AC output of the first generator to the DC bus; and a second rectifier (D2) for coupling an AC output of the AC storage device to the DC bus.
