  • Patent number: 11936185
    Abstract: Systems and methods for Energy Storage-based Packetized Delivery of Electricity (ES-PDE) are disclosed that are radically different from the operation of today's grid. Using ES-PDE, the loads are powered by the energy storage systems (ESS) the majority of the time and only receive packets of electricity periodically to charge the ESSs. Therefore, the grid operators can schedule the delivery of electricity packets to utilize the existing grid infrastructure. Since the customers are powered by the co-located ESSs they are not impacted by the grid operation in short term. Therefore, when grid outages occur, the customers still have power for some time, giving the grid more time to be fully restored.

  • Patent number: 11917058
    Abstract: Intelligent impedance injection modules (IIM)s are currently being used for line balancing and overcoming local disturbances on High Voltage (HV) transmission lines of an HV power grid. These distributed IIMs are connected and/or coupled to the HV transmission lines and operate with a pseudo ground at the voltage of the HV transmission line. In order to operate effectively, the IIMs need to communicate with other distributed IIMs across the three phases of the HV grid and also communicate with local intelligent centers LINCs that connect to and synchronize operations across each group of the distributed IIMs in a local region of the HV power grid. Systems and methods are presented for effective and secure sub-cyclic speed communication to and from the distributed IIMs, distributed IIMs to LINCs and substations to enable coordinated actions. Further the distributed IIMs and LINCs receive GPS signals and use the GPS clock for synchronizing operations.

    Abstract: Systems and methods are provided for managing power usage in mining environments. The amount of power needed to operate a set of electrical machines that are to run simultaneously is determined. Power usage by the electrical machines during a time period can be predicted based on how much power is expected to be needed by each machine. If the predicted power usage exceeds a threshold power usage, power to one or more electrical machines in the mining environment is restricted so that actual power usage in the mining environment does not exceed the threshold power usage during the specified time period. The electrical machines which will have power restricted thereto can be selected based at least in part on relative priorities for the electrical machines in the set. Power can be restricted to machines as a whole (an effective shutdown), or to specific operations of the machines.

  • Patent number: 11738238
    Abstract: This invention is used to control the duration of time it takes to charge any device, depending on how many units the user has taken out of their fitness goal. This invention connects to a fitness device such as a smart watch and retrieves the amount of units the user has completed. Being conditional on how many units the user has taken, the device will either charge at a normal pace or proportionally slower. For example, if the user's daily goal was 10,000 units and they completed 5,000 units, their device would charge half its normal pace. This invention charges the device more slowly by pausing the charges for periods of time.

  • Patent number: 11551323
    Abstract: To ensure safety of people needing to service a low-voltage network of an electric power distribution system, dwellings being connected to this network may include autonomous units for producing electricity, thus generating voltage and endangering the people servicing the work. Data are obtained from consumption records from the meter of each dwelling, in regular time intervals, and meteorological data are also obtained in the geographical area of these dwellings, in order to identify at least some weather conditions conducive to the production of energy by autonomous units. A model is then applied for detecting, based on the first and second data, a coincidence between periods of lower consumption measured by a meter and weather conditions conducive to electricity production by autonomous units during these periods. Therefore, information on the presence of autonomous units in the dwelling can be deduced and given to people before their servicing.

  • Patent number: 11551176
    Abstract: Methods and systems for evaluating economic viability of a proposed microgrid, including uncertain variables are disclosed. One or more candidate distributed energy resources can be selected for use within a proposed microgrid. An investment cost and an operation cost of the one or more candidate distributed energy resources can be determined. A cost of drawing power from a main power grid can be compared to a sum of the investment cost and the operation cost of the one or more candidate distributed energy resources. The proposed microgrid can be identified for installation when the sum of the investment cost and the operation cost is less than the cost of drawing power from the main power grid.

  • Patent number: 11537412
    Abstract: A new approach is proposed that contemplates systems and methods to support utilizing security device plugins for external device control and monitoring in a secured environment. A plugin that implements one or more functionalities to communicate with and to control operations of an external device is provided to a network security device/appliance. The plugin is then loaded to the network security appliance and integrated with a software running on the network security device, wherein the software obtains the functionalities offered by the plugin. A communication link is established between the plugin of the network security device and the external device following a communication protocol. The network security device is then configured to issue/receive one or more commands to/from the external device following the communication protocol to monitor and collect information from and/or control or be controlled by the external device remotely.

  • Patent number: 11476693
    Abstract: Systems and methods of improving storage and consumption of electricity according to time-based tiered criteria are disclosed. An energy storage system controlled by a processor is optionally connected to a utility power grid, a photovoltaic (PV) power source, and/or electrical loads. Time-of-use (TOU) rates (or similar tiered criteria) are input into the processor, which sets charge and discharge profiles according to the criteria, the arrangement of time windows, and the user's preferences. Energy is stored or discharged according to these profiles. Additionally, the energy storage system may record the production and consumption patterns of the user over time, and use this information to modify the profiles for enhanced performance by allowing discharge during non-peak windows. Benefits include reduced electrical cost to the user, reduced strain on the utility power grid during peak consumption hours, and enhanced performance with regard to any other criteria input into the processor.
