The system may be used with traditional utility provided power as well as locally generated solar, wind, and any other types of power generation technology. In some embodiments, the energy storage unit and the control unit are housed in the same chassis. In other embodiments, the energy storage unit and the control unit are separate. In another embodiment, the energy storage unit is integrated into the chassis of an appliance itself. | 2022-02-10 |
20220045512 | INVERTER OF GRID-CONNECTED PHOTOVOLTAIC POWER GENERATION SYSTEM, STARTUP APPARATUS, METHOD, AND SYSTEM - This application discloses an inverter of a grid-connected photovoltaic power generation system. The inverter includes a grid-connected inverter unit, an alternating current auxiliary power supply, and a startup apparatus. The alternating current auxiliary power supply is configured to convert an alternating current from an alternating current power grid into a direct current. An input terminal of the grid-connected inverter unit is connected to a bus capacitor. The startup apparatus is configured to: obtain an alternating current from the alternating current power grid, convert the alternating current into a direct current, and then provide the direct current to the bus capacitor, to start the grid-connected inverter unit. By using the inverter, the grid-connected photovoltaic power generation system can be started normally when there is insufficient or no sunlight, to allow scheduling of the grid-connected photovoltaic power generation system to be normally performed. | 2022-02-10 |
20220045513 | DEVICE AND METHOD WITH POWER CONTROL - A microelectronic device includes: a photovoltaic module configured to convert a light energy into an electric energy; a converter configured to convert a voltage output from the photovoltaic module into a predetermined voltage; a capacitor configured to store an electric energy transferred from the converter; and a controller configured to predict an available current of a next time slot based on the electric energy stored in the capacitor, and determine a consumed current of a load system of the next time slot based on the predicted available current. | 2022-02-10 |
20220045514 | Electrical System for Providing Electricity - In one embodiment, a first electrical network includes one or more first electricity producing elements, and a first conductive path electrically couples at least some of those elements to an end user's electrical wiring, which is coupled by a second conductive path to one or more second electricity producing elements of a public utility electrical network. A switch coupled between the first conductive path and the end user's electrical wiring and between the second conductive path and the end user's electrical wiring electrically isolates the first electrical network from the public utility electrical network. Based on a determination of whether an amount of electricity used by the end user exceeds an amount of electricity the first electrical network is capable of providing to the end user, the switch either draws electricity only from the first electrical network or from both the first electrical network and the public utility electrical network. | 2022-02-10 |
20220045515 | Apparatus of Power-Generating Solid Oxide Fuel Cells Tied to Grid - An apparatus of solid oxide fuel cells (SOFC) is provided. The SOFCs generate power and are grid-tied. The apparatus comprises a power-generating side; and a grid-connecting side using an elementary household power management. The apparatus solves problems like low voltage, high current, voltage oscillation, voltage dips, long generator-starting time, etc. The apparatus is not only used as a stable power supply (base load), but also helps adjust the regional peak electricity demands. The features include the following: 1. A grid is tied, where output power does not pass through a direct-current boost converter and, thus, has no loss from it. 2. Injures, including voltage oscillation and sudden unloading after dumping, are reduced for avoiding further damages to cell sheets. 3. With the coordination of elementary power management and the integration of grid, the limitation of long-awaiting generator-starting time is crossed out and convenience of immediate power use is achieved. | 2022-02-10 |
20220045516 | POWER FLOW CONTROL DEVICE AND WIND FARM INCLUDING A POWER FLOW CONTROL DEVICE - A wind farm for supplying electrical power into a supply grid. The farm includes wind power installations, a farm grid connecting the installations, and a power flow control device. The power flow control device is configured to connect the farm grid and the supply grid such that an electrical power generated by the installations can be supplied into the supply grid. The power flow control device has at least: a DC link configured to conduct at least the electrical power generated by the installations, an electrical energy store connected to the DC link, an inverter connected to the DC link and configured to inject at least the electrical power generated by the installations into the supply grid, and a controller configured to drive the inverter in such a way that the farm, at the supply grid, in the steady state appears to be dynamic like an electromechanical synchronous machine. | 2022-02-10 |
