  • Patent number: 10965123
    Abstract: A detection and location-based active protection method for flexible DC distribution systems with multi-terminal distributed photovoltaic sources is disclosed. The disclosed protection method actively utilizes the coordinated control between local protection and the converters in the DC distribution system. The converter can then be modified to become an injection source with characteristic signal, providing a known fault signal to build a clear protection boundary. The disclosed protection method can distinguish the correct faulted area by calculating the harmonic impedance of the characteristic signals. Compared with existing DC protection techniques, this disclosed method does not require additional injection equipment and modification of the DC distribution system configuration, nor does it need high data sampling frequency. The disclosed technique is also unaffected by measuring noise and cable-distributed capacitance.

  • Patent number: 10951032
    Abstract: Systems and methods for supplying power (both active and reactive) at a medium voltage from a DCSTATCOM to an IT load without using a transformer are disclosed. The DCSTATCOM includes an energy storage device, a two-stage DC-DC converter, and a multi-level inverter, each of which are electrically coupled to a common negative bus. The DC-DC converter may include two stages in a bidirectional configuration. One stage of the DC-DC converter uses a flying capacitor topology. The voltages across the capacitors of the flying capacitor topology are balanced and switching losses are minimized by fixed duty cycle operation. The DC-DC converter generates a high DC voltage from a low or high voltage energy storage device such as batteries and/or ultra-capacitors. The multi-level, neutral point, diode-clamped inverter converts the high DC voltage into a medium AC voltage using a space vector pulse width modulation (SVPWM) technique.

  • Patent number: 10850619
    Abstract: A power conversion device includes a backup power source as a power source for a discharge controller that discharges electric charges of a capacitor, and an abnormal state in the backup power source or loads is not capable of being dealt with when power is supplied to loads from the backup power source, which makes an output voltage of the backup power source be in an abnormal state. In order to solve the problem, when an abnormality occurs in the backup power source or in loads and the abnormality is detected in power supply from the backup power source, a place where the abnormality occurs is specified. When the specified place where the abnormality occurs is a load, power supply to the load is stopped, thereby preventing the output voltage of the backup power source from being abnormal even when an abnormality occurs in part of power supply destinations.

  • Patent number: 10833530
    Abstract: Methods and systems for performing network reconfigurations for networks including one or more renewable energy devices are described herein. In one exemplary embodiment, a network reconfiguration engine is used to determine an energy level of one or more renewable energy devices within the network. The reconfiguration engine is then capable of determining an optimal path for the network reconfiguration such that a least portion of the network's load is impacted, as well as a minimal number of switching operations are needed. The optimal path also, in one embodiment, includes performing a resiliency estimation for the post-network reconfiguration topology. An updated relay setting for the post-network reconfiguration topology is determined, and a status of any other engines associated with the reconfiguration is determined, after which the network reconfiguration is performed.

  • Patent number: 10804737
    Abstract: The described embodiments relate to systems, methods, and apparatuses for controlling energy resources available to micro-grids of a city based on mobility patterns of people moving within the micro-grids. The mobility patterns can be identified using a network of sensors within each micro-grid for collecting data related to the movement of people within the micro-grids. The mobility patterns can be used to estimate energy demand for each micro-grid and prioritize the energy demands to determine the energy resources that would be suitable for supplying power to each micro-grid. This allows for micro-grids to dynamically and efficiently change their power sources according to predictions about the movement of people within the micro-grids.
