摘要： Various embodiments provide methods and systems for monitoring and controlling electrical components of an electrical distribution network. In an embodiment, a method, performed by an automated controller, includes receiving values corresponding to electrical parameter(s) associated with multiple connection points in the electrical distribution network, the values being acquired via electrical sensor(s). The method also includes transmitting the values to a local area supervisory controller, upon receiving a measurements-related request. The method further includes receiving a control message from the local area supervisory controller, the control message including predefined conditions and information indicating the automated controller to wait for the predefined conditions to be met between two connection points having a connection point to which a distributed energy resource (DER) is connected. The method further includes controlling an operation of contactor(s) positioned between the two connection points based at least on the predefined conditions.

摘要： Systems, devices, and methods for energy systems that include one or more modules are configured to connect to a power grid. Each module outputs a respective voltage waveform and/or a current waveform to a load. A controller is configured to periodically cause at least a portion of the one or more modules to output an increased voltage and/or current level at a specified harmonic frequency. An islanding detector is configured to detect, based on an impedance of the grid, when the one or more modules are in an island condition.

摘要： An apparatus and methods are disclosed for monitoring the operation of an electrical power-transfer system and detecting and handling hazardous and undesirable system states. In accordance with one embodiment, an electrical signal is injected into the electrical power-transfer system. During or after the injection of the electrical signal, an electrical property between a first sensor and a second sensor are measured to obtain a measurement. The electrical power-transfer system is determined to be in a hazardous state based on the measurement, and in response to the determination one or more actions are performed to correct the hazardous state.

摘要： A method for operating a multi-level bridge power converter of an electrical power system connected to a power grid includes receiving a commanded state for one or more switching devices thereof. The method also includes receiving a gate-emitter voltage of one or more of the switching devices. Further, the method includes comparing, via at least one comparator, the gate-emitter voltage of the one or more switching devices to a reference voltage range corresponding to the commanded state of the one or more switching devices. In addition, the method includes determining an actual state of the one or more switching devices based on the comparison. Thus, the method also includes implementing a control action based on the actual state of the one or more switching devices.

摘要： Provided is a method for detecting overloading of devices for load transfer in an open-loop power grid, including: constructing a power supply tree graph; determining a target device and a standby power supply; determining a target node, a target set, and one or more target subsets; for each of the target subsets, determining nodes in said target subset between which the parent-child relationship is reversed due to the load transfer, and performing overload detection on each device corresponding to one of the nodes or an edge on a path connecting the nodes; and determining two nodes between which a direct parent-child relationship is generated from nonexistence due to the load transfer, and performing overload detection on each device corresponding to a node or an edge on a path connecting a parent node of the two nodes and a common parent node.

摘要： Systems and methods comprising a metering device located on an electricity distribution grid, the metering device comprising one or more processors and memory. The metering device can detect a drop in characteristic of electricity below a threshold indicating a fault on the electricity distribution grid. The metering device can generate, responsive to the drop in the characteristic of electricity below the threshold, a time series of a rate of change of the characteristic of electricity for a predetermined number of cycles subsequent to the detection of the drop. The metering device can determine, based on a comparison of the time series of the rate of change with a predetermined pattern, a location of the metering device on the electricity distribution grid relative to a location of the fault on the electricity distribution grid.
