20140117770 | POWER CONVERTER - A multi-source power converter is proposed to permit bidirectional DC to AC conversion from n (n≧2 and nεN) DC voltage sources to an AC load with a reduced number of switches, and DC to DC conversion. Both single and three phases AC load are considered. The proposed topology consists in a single stage of conversion, and therefore a high efficiency can be expected for the system. Any type of DC sources can be used in the system (fuel-cell, battery, ultra-capacitor, photo-voltaic cells, DC bus, DC to DC or AC to DC converter, etc.). The AC load can be either single or three phases (single-phase AC grid/microgrid, three-phase electric machines, induction machine, synchronous machine, etc.). There is no requirement for the n DC voltage source values; they can be equal or different and they can be used individually or together by the converter to generate the AC output. If different DC voltage values are used, the converter can be controlled to generate a multi-level AC voltage. This permits to improve system's voltage and current power quality and to reduce electro-magnetic interferences (EMI). Therefore gains on both differential and EMI filters design can be expected. | 05-01-2014 |
20140129040 | ADAPTIVE ENERGY MANAGEMENT SYSTEM - Systems, methods, and devices related to a microgrid system for providing power to a facility. A self-contained power system provides power to a facility using a combination of power storage elements and renewable energy sources. A connection to an external power grid may also be provided. The system optimizes power flow to the facility using power from the storage elements and the renewable energy sources and, if necessary, the external power grid. The optimization process predicts future power usage by the facility using power usage data from a predetermined time window. The optimization process can also take into account predicted energy generation amounts by the renewable energy sources. To optimize economic effects, the optimization process can also determine whether to buy and when to buy power from the external power grid. | 05-08-2014 |
