REAL-TIME ESTIMATION OF CONTRIBUTIONS FROM CLASSES OF ENERGY GENERATORS IN RESIDUAL LOAD SIGNALS
Various embodiments manage energy generation in a power generation and distribution system. In one embodiment, a set of residual load data is obtained for a given period of time measured at one or more nodes within a power generation and distribution system. The set of residual load data encodes a set of power flow signals. The set of residual load data is analyzed. An amount of power contributed to the set of residual load data by at least one energy generator class is determined based on the analysis of the set of residual load data.
System for controlling energy supply across multiple generation sites
A method of controlling energy supply in an energy distribution network comprising a first energy generation facility located at a first site and a second energy generation facility located at a second site is disclosed, where the first and second energy generation facilities are adapted to supply energy to the energy distribution network. The method comprises, at a control system: receiving a first energy output measurement indicating energy output from the first energy generation facility to the distribution network; receiving a second energy output measurement indicating energy output from the second energy generation facility to the distribution network; determining a combined energy output to the distribution network from the first and second energy generation facilities based on the first and second energy output measurements; comparing the combined energy output to a combined output limit defined for the first and second energy generation facilities; and controlling one of the energy generation facilities to adjust energy output to the distribution network in dependence on the comparison.
Safety power disconnection for power distribution over power conductors to power consuming devices
Safety power disconnection for remote power distribution in power distribution systems is disclosed. The power distribution system includes one or more power distribution circuits each configured to remotely distribute power from a power source over current carrying power conductors to remote units to provide power for remote unit operations. A remote unit is configured to decouple power from the power conductors thereby disconnecting the load of the remote unit from the power distribution system. A current measurement circuit in the power distribution system measures current flowing on the power conductors and provides a current measurement to the controller circuit. The controller circuit is configured to disconnect the power source from the power conductors for safety reasons in response to detecting a current from the power source in excess of a threshold current level indicating a load.
METHODS AND APPARATUS FOR MAKING A TIME-SYNCHRONISED PHASOR MEASUREMENT
The invention enables the complexity and cost of implementing a PMU network and/or a control system to be substantially reduced by eliminating the requirement for power supplies, GPS equipment, and telecommunication equipment at each measurement and/or control location. In the case of implementing a PMU network, creation of synchrophasors is achieved by centralising the determining of phasors and corresponding time-stamps at a location away from the actual measurement locations. Alternatively, or in addition to time-stamping phasors, the invention enables the time-stamping of any received signals and/or measurements derived from those signals. These signals are received from appropriate sensors distributed along optical fibres such as may be incorporated in modern power cables. Likewise, control signals can be communicated along optical fibres such as may be incorporated in modern power cables, and a number of approaches to ensuring control signals are received by the intended control modules are provided. It is envisaged that either or both the PMU network and control system can be implemented in a power network by exploiting existing optical fibre infrastructure in this way. It is also envisaged that control signals can be transmitted dependent on analysis performed on synchrophasors.

The method further includes transmitting the specified type of simulation and the at least one initial condition from the user device to a computing platform; receiving from the computing platform a result of the simulation at the user device; and visualizing the result of the simulation with the user interface. The type of simulation can be an N-k contingency analysis simulation, where k is equal to zero, 1 or greater than 1.

A power management system may include multiple interconnected power supply and control units that plug directly into a standard residential power outlet. Together, the interconnected power supply and control units may provide a distributed power backup system in the form of a home energy nano-grid.

Interface circuitry with multiple direct current power contacts
Embodiments may include apparatuses, systems, and methods for direct current power distribution. An apparatus includes a first power contact, a second power contact, and a controller coupled to the first power contact and the second power contact. The first power contact is coupled to a first power distribution line supplying DC power to the first power contact at a first voltage level. The second power contact is coupled to a second power distribution line supplying DC power to the second power contact at a second voltage level different from the first voltage level. The controller is to control a first power connection established with the first power contact based on a first power contract, or a second power connection established with the second power contact based on a second power contract. Other embodiments may be described and/or claimed.
Supplemental voltage controller for radio frequency (RF) antennas
This disclosure describes techniques for identifying and mitigating a voltage loss in a power transmission to a Remote Radio Unit (RRU) associated with Radio Frequency (RF) antennas of a telecommunications network. More particularly, a Supplemental Voltage (SV) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a primary Direct Current (DC) power source to the RRU and selectively cause a supplemental DC power source to transmit a supplemental voltage to the RF antennas. The SV controller may cause a supplemental DC power source to transmit a supplemental voltage to the RRU based on an empirical data analysis, sensory data analysis, or current environmental metadata. Further, the SV controller may determine whether the primary DC power source has suddenly ceased transmitting power to the RRU, and in doing so, cease transmission of a supplemental voltage to the RRU.
