摘要： The present application discloses a multi-channel grid-connected power generation system and a control method therefor, which lowers the system cost while reducing no-load losses of all step-up transformers. Multi-channel energy conversion devices in the system are each connected in parallel, by means of a step-up transformer, to the same collector line, one end of the collector line is connected to the grid by means of a switch device, and the on-off switching of the switch device is controlled by a control unit. The control unit sends a switch-off command to the switch device when same has determined that all of the energy conversion devices have entered a non-operating state. In the off state of the switch device, at least one energy conversion device, when meeting a start-up condition, starts to operate as a voltage source, and establishes an alternating-current voltage, so that the phase difference and amplitude difference of voltages at two ends of the switch device are both stable within an allowable error range. Then, the control unit sends a switch-on command to the switch device, and the other energy conversion devices start to operate as a current source to transfer energy to the grid.

摘要： An energy-recycling device and a DC voltage-boosting device thereof is disclosed. The DC voltage-boosting device includes a first phase controller, an interleaved voltage booster, a second phase controller, and a phase-shift voltage converter. The first phase controller generates a first PWM signal and a second PWM signal. The interleaved voltage booster receives an input DC voltage, the first PWM signal and the second PWM signal and increases the input DC voltage to a supplying DC voltage. The second phase controller receives the supplying DC voltage and a setting voltage, thereby generating third PWM signals. The phase-shift voltage converter receives the third PWM signals and the supplying DC voltage and converts the supplying DC voltage into a stable DC voltage.

摘要： Unintentional islanding (UI) of a circuit of distributed energy resources (DERs) may leave area electrical power systems (EPS), external to the DER circuit, energized. Thus, UI detection methods have been developed to detect unintentional islanding and trigger a UI response. However, individual UI detection methods have various deficiencies. Thus, a consensus-based UI detection process is disclosed that builds a consensus from multiple UI detection sources, optionally implementing different UI detection methods. The redundancy in this consensus-based UI detection process provides robust, sensitive, selective, and cybersecure UI detection for the entire DER circuit. For example, the consensus-based UI detection process may eliminate or reduce non-detection zones, avoid false positives, thwart cyber-attacks, and/or the like.

摘要： A site monitoring method uses an electrical socket device to collect current data of an electrical appliance that is electrically connected to the electrical socket device. Based on the current data, a management server can derive a user behavior in connection with using the electrical appliance, and send out a warning message when the user behavior thus derived is abnormal.

摘要： Systems and methods for the creation of a centrally controlled DC and AC power rail system within a structure. The rails utilize a centralized controller along with a plurality of distributed controllers to allow for power in the rails to be selectively distributed or not distributed to outlets attached to the rails. This allows for power to be distributed without the need for users to utilize hardwired switches, but to instead utilize generally wireless switch modules, which may be implemented in hardware and/or software to control the outlets. It also allows for devices designed to utilize DC power to be directly supplied with such power from the DC power rail without the need to include onboard AC-DC converters with each device.

摘要： In the present legacy electrical power generation and distribution system, the power quality delivered to end consumers is being degraded by a number of disruptive technologies and legislative impacts; especially with the rapidly increasing myriad of privately owned and operated domestic and commercial distributed energy generation (DEG) devices connected at any point across a low voltage (LV) distribution network. The present invention bypasses this increasing critical DEG problem by offering a solution comprising an energy processing unit (EPU) that is installed at the edge of the high voltage (HV) transmission grid.

摘要： A power control method for performing phase control is provided. The method includes generating a zero-crossing signal that indicates a first level if an absolute value of AC voltage is smaller than a predetermined value, and indicates a second level if the absolute value of the AC voltage is larger than the predetermined value; detecting a zero-crossing width and a non-zero-crossing width, the zero-crossing width being a time width for a case where the absolute value of the AC voltage is smaller than the predetermined value, the non-zero-crossing width being a time width for a case where the absolute value is larger than the predetermined value; detecting a frequency and a voltage value of the AC voltage based on the zero-crossing width and the non-zero-crossing width; and performing phase control depending on the frequency and the voltage value.
