摘要： A system includes multiple electrical nodes connected in series to a primary power source via transmission lines. Each node includes a power converter that can receive first power from the primary power source or another upstream node. The power converter can change a voltage level and/or a frequency of the first power. Each node also includes a high-speed synchronous rotating machine (HSRM), which includes an inertial storage flywheel, a rotating excitation assembly, stator windings, and a synchronous motor coupled to an induction generator. The HSRM can boost a voltage level between an input and output to compensate for a voltage drop of the first power. At least one of the nodes further includes an inductive power coupler to electrically couple the node to a mobile power source that provides second power to the node and receives a portion of the first power from the node using contactless inductive power transfer. The system includes a combination of AC and DC power transmission techniques and associated bidirectional power converters.

摘要： A method for controlling a photovoltaic rapid shutdown system, an inverting system, and a photovoltaic rapid shutdown system. In the photovoltaic rapid shutdown system, the inverting system determines whether the photovoltaic rapid shutdown system is to enter a safe mode, introduces fluctuations onto a direct-current bus in the photovoltaic rapid shutdown system in response to the photovoltaic rapid shutdown system being not to enter the safe mode, and otherwise does not introduce the fluctuations onto the direct-current bus. A shutdown device for a photovoltaic module determines according to an output parameter thereof whether an electrical parameter on the direct-current bus connected to the shutdown device meets a preset condition, controls itself to be turned on or maintains itself being on in response to the electrical parameter meeting the preset condition, and otherwise controls itself to be turned off or maintains itself being off.

摘要： A power management system for managing at least one power generation system connected to an electrical grid and at least one energy storage device connected to the electrical grid, wherein the energy storage device is charged or discharged in a time period in which the reliability of the prediction of the amount of power generation and the power demand per time period is high based on a predicted amount of power generation which is an amount of power generation of the power generation system predicted for each time period and a predicted power demand which is a power demand for the electrical grid. Thus, more proper energy management can be performed.

摘要： A method of isolating or suppressing forced oscillations in a power grid by utilising a wind turbine system comprising a wind turbine for capturing wind power, a generator driven by the wind turbine, and a power converter configured to control the rotational speed of the generator for controlling a supply of active power to the power grid. The power converter is further configured to supply reactive power to the power grid independently from the supply of active power. The method comprising the steps of: obtaining measurements of a forced oscillation occurring within the power grid; controlling the converter to supply active and reactive corrective oscillating power to the power grid in response to the measured forced oscillation such that the corrective oscillating power suppresses the forced oscillations.
