The present invention pertains to a power monitoring device configured in such a manner as to make it as easy as possible to perform power monitoring, notification and control for customers in coordination with the power utilization rate of a utility grid. The power monitoring device is provided with: a target power setting unit that receives, from outside, information indicating the power utilization rate of a utility grid by time, and, with regard to time periods in which the power utilization rate is greater than a prescribed threshold value, reduces preset target power consumption levels, and sets target power consumption levels by time; and an assessment and control unit that obtains, from outside, the power usage of power-consuming devices, and performs control in order to save power for the power-consuming devices in time periods in which the obtained power usage exceeds the target power consumption level.

A load shed module configured to be connected in series between a power supply and a load is disclosed. A separate load shed module is connected in series between each load and the power supply. The load shed module determines the frequency of the Voltage supplied from the power supply. Based on the frequency, the load shed module determines if utility power is connected or if a generator is connected. If the generator is connected and the frequency of the voltage goes outside of a desired operating range for a preset time, the load shed module disconnects the load from the power supply. Each load shed module includes a priority setting and reconnects its corresponding load after a predetermined time corresponding to the priority setting.

The present disclosure is directed to energy storage and supply management system. The system may include one or more of a control unit, which is in communication with the power grid, and an energy storage unit that stores power for use at a later time. The system may be used with traditional utility provided power as well as locally generated solar, wind, and any other types of power generation technology. In some embodiments, the energy storage unit and the control unit are housed in the same chassis. In other embodiments, the energy storage unit and the control unit are separate. In another embodiment, the energy storage unit is integrated into the chassis of an appliance itself.

For optimizing a chronological development of consumption of electric power by a group of different consumers with regard to a supply of electric power including electric power from at least one wind or solar power generator, characteristic time curves of the consumption of electric power are determined at a high temporal resolution. A prognosis is made of a chronological development of the supply of electric power from the at least one power generator for a future period of time, and a plan for apportioning electric power to the individual consumers within the future period of time is made based on the characteristic time curves of the consumption of electric power by the individual consumers, the prognosis, and user goal setting by a user of the consumers resulting in different weightings of consumption of electric power by different consumers and supply of electric power by different power sources.

An energy management system is provided for controlling a controlled device connected to an energy supply network, which controlled device includes multiple energy-converting elements, wherein the sum of maximum energy conversions of the energy-converting elements is at least 3 kW. The energy management system may include modules that each provide functions used in the control of the controlled device, wherein planning function(s) for planning a future energy conversion of the energy-converting element(s), sensing function(s) for sensing parameter(s) that concern an instantaneous energy conversion of the energy-converting element(s), and control function(s) for specifying control parameter(s) that influence an energy conversion of the energy-converting element(s) are provided as functions. Each module may be designed to communicate with other one(s) of the modules via a communication connection, whereby functions of the module can be used by the other module and/or functions of the other module can be used by the module.

A method for operating a power management device for controlling an operating device connected to a power supply network, in which the maximum demanded and/or provided output of the controlled operating device is at least 3 kW, is disclosed. An information data set is received which describes coupling information or a temporal progression of coupling information from a server device associated with a network provider of a power supply network, the coupling information describing a relationship between a device load of the operating device and a target variable to be optimized. A load profile is determined which describes a predicted temporal progression of the device load by optimizing the load profile with respect to the target variable. The load profile is provided to the server device, and the power management device may control the operating device according to a default value which is predetermined based on the load profile.

A power system of a consumer premises includes a circuit breaker to provide power to an electrical circuit and a current sensor mounted proximate a connection of the circuit breaker. The current sensor generates data that a controller uses to compute current draw for the circuit fed by the circuit breaker. Based on the current draw information, the controller can determine how much real and reactive power is being drawn by individual circuits. The controller can use that information to trigger a power converter to adjust operation to change the quadrant of operation of the current vector.

A circuit arrangement for controlling a plurality of loads of an electrical appliance has a main control module, arranged in a first voltage range and configured to generate control data for controlling a plurality of loads, which are arranged in a second voltage range. A galvanic isolation unit transfers the control data via a galvanically isolated connection from the first voltage range to the second voltage range. At least one auxiliary control module has a plurality of control outputs for the loads and an LED driver for operating a corresponding plurality of LED arrangements via the of control outputs, and/or a general-purpose input/output expansion circuit with programmable control outputs. Based on the control data, the auxiliary control module identifies a first control output for controlling the first load and causes the first load to be controlled via the first control output.

The present invention relates to a dish warming system that includes a plurality of dish warming assemblies each having a plate with a power source and a heat element. The power source of each dish warming assembly allows for the concurrent charging of the plurality of dish warming assemblies while stacked. The heat element in some iterations of the system includes a pressure switch that activates the heat element when a dish is placed on the dish warming assembly.
