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.

A method for controlling an electrical consumer is provided. The electrical consumer is coupled to an electricity supply grid using a frequency converter. The electricity supply grid has a line voltage and is characterized by a nominal line voltage. The electricity supply grid is monitored for a grid fault in which the line voltage deviates from the nominal line voltage by at least a first differential voltage. When the grid fault occurs, the electrical consumer remains coupled to the electricity supply grid, and a power consumption of the electrical consumer is changed on the basis of the deviation of the line voltage from the nominal line voltage.

The decentralized controllers generate decentralized control signals for the local controllers based on measured voltages and currents of the electrical power grid and the inverters. The centralized controller transmits centralized control signals to the local controllers to maintain a constant voltage on the common DC bus based on a predicted DC load.

Described herein are methods and systems for detection and notification of electrical power outages and power quality. A sensor coupled to a circuit transmits a keepalive packet to a server. The sensor detects an input signal generated by electrical activity. The sensor generates an output signal based upon the input signal. The sensor monitors the output signal. During a clock cycle, the sensor determines whether a rising edge occurred and transmits a fault packet to the server when the rising edge occurred prior to a predetermined clock value or when no rising edge occurred. The server receives the fault packet from the sensor and listens for keepalive packets. The server transmits a power outage notification when no keepalive packets are received for at least a defined time period after the fault packet is received. The server transmits a power restoration notification when one or more keepalive packets are subsequently received.

A distributed power system wherein a plurality of power converters are connected in parallel and share the power conversion load according to a prescribed function, but each power converter autonomously determines its share of power conversion. Each power converter operates according to its own power conversion formula/function, such that overall the parallel-connected converters share the power conversion load in a predetermined manner.
