A monitoring control apparatus includes: a display controller to display an alarm screen for notifying a plurality of abnormalities occurring in a monitoring target device provided in an electric power system; a selector to select a first abnormality among the plurality of abnormalities; a degree-of-association calculator to calculate, for each of one or more other abnormalities except for the first abnormality among the plurality of abnormalities, a degree of association of the other abnormality with the first abnormality; and an extractor to extract the other abnormality as an associated abnormality associated with the first abnormality when the degree of association of the other abnormality is not less than a threshold. The alarm screen includes an associated alarm for notification of the extracted associated abnormality.

The present disclosure provides a switch circuit and a control method thereof, a smart switch and a control system. The switch circuit includes a wireless communication module, a switch module coupled to a load, a switch-on power obtaining circuit, an energy storage circuit coupled with the wireless communication module and a switch-off power obtaining circuit. The load is coupled with a neutral wire. The switch-on power obtaining circuit is configured to output a first current to the energy storage circuit in response to the switch module being switched on. The switch-off power obtaining circuit is configured to output a second current to the energy storage circuit via the second power supply terminal in response to the switch module being switched off. The second current is less than the first current.

A building management system includes building equipment configured to consume electrical energy and generate thermal energy, thermal energy storage configured to store at least a portion of the thermal energy generated by the building equipment and to discharge the stored thermal energy, electrical energy storage configured to store electrical energy purchased from a utility and to discharge the stored electrical energy, and a controller. The controller is configured to determine, for each time step within a time horizon, an optimal amount of electrical energy stored or discharged by the electrical energy storage by optimizing a value function.

A remotely controlled switching module that provides switching and preferably dimming functions for one or more AC or DC power distribution lines. The inventive module is preferably sized to fit within existing outlet and switch boxes, while still leaving enough room for the conventional components that are also housed in such enclosures. Remote control is provided wirelessly—preferably using an existing wireless communication protocol. Local control is preferably also provided for the inventive switching module. Local control inputs preferably allow control via existing components—such as two-pole light switches.

The provided materials are a grid load interactive control method and terminal based on adaptive load characteristics and a storage medium. The method includes: receiving a test presetting message sent by a master station and sending message reply information to the master station; parsing the test presetting message to obtain a test presetting instruction; building a test environment and generating a virtual action exit in the test environment when the test presetting instruction generates a record; and sending instruction response including the record to the master station so as to cause the master station to determine whether a test is successful according to the record.

A method for analyzing power quality events in an electrical system includes processing electrical measurement data from or derived from energy-related signals captured by at least one metering device in the electrical system to generate at least one dynamic tolerance curve. Each dynamic tolerance curve of the at least one dynamic tolerance curve characterizes a response characteristic of the electrical system at a respective metering point in the electrical system. The method also includes analyzing the at least one dynamic tolerance curve to identify special cases which require further evaluation(s)/clarification to be discernable and/or actionable. The at least one dynamic tolerance curve may be regenerated or updated, and/or new or additional dynamic tolerance curves may be generated, to provide the further clarification. One or more actions affecting at least one component in the electrical system may be performed in response to an analysis of the curve(s).

A power supply unit, an electrically operated system and a method for operating an electrical system, wherein the power supply unit connects through a basic supply voltage or a buffer voltage, which is provided by an energy store unit, where to perform a controlled switch-on process of the electrical loads, a switch-on delay time is specified, after the expiration of which the basic supply voltage or the buffer voltage is connected through at the output of the power supply unit, and where to perform a controlled switch-on process of the electrical loads, a voltage is output only when a charge level of the energy store unit is greater than or equal to a threshold value of the energy store charge level such that switch-on management for power supplies that ensures absolutely safe interruption-free and thus trouble-free start-up of a plurality of electrical loads is achieved.

Aspects of the subject disclosure may include, for example, embodiments detecting and correcting load imbalance on power supply phases within a managed scope using a software controlled power switch matrix that is resident in each power distribution unit supplying power in the managed scope. Managed scope could include a plurality of power distribution units supplying a plurality of circuit or equipment loads in a plurality of premises.
