    摘要: This document discloses a solution for a method of monitoring an electric power grid. According to an aspect, a method comprises: obtaining, on a basis of one or more physical stimuli generated endogenously in the electric power grid, a first set of measurement data associated with a first location of the electric power grid, the physical stimuli belonging to nominal or near-nominal operation of the electric power grid and generating at least one of voltage fluctuation and current fluctuation that exceeds at least one threshold; computing a grid strength of the first location of the electric power grid on the basis of the first set of measurement data; mapping the grid strength to a grid strength of a second location of the electric power grid on the basis of the first set of measurement data and correlation between electrical characteristics of the first location and the second location.

    摘要: Methods, computer software and apparatus for use in an electric power grid are described. Measurement data is received intermittently or continuously from a plurality of measurement units, indicating values of at least one measured characteristic at respective measurement locations. The at least one is characteristic is monitored, and it is determined, based on the monitoring, that there has been a change in electric power flow in the electric power grid. Responsive to the determination, component data is accessed relating to characteristics of components of the electric power grid involved in provision and/or consumption of electric power. Based on received measurement data relating to the change and the accessed component data, a power flow characteristic of the grid in a given time period is determined.

    摘要: Methods, and apparatus for determining inertia within a synchronous area of an electric power grid are described. A frequency characteristic relating to a frequency of electricity flowing in the electric power grid is measured, a magnitude relating to a power flow modulation is determined based on data relating to power characteristics of one or more power units arranged to consume electric power from and/or provide real and/or reactive electric power to the electric power grid, and a frequency response characteristic associated with at least one area of the electric power grid is determined on the basis of the measured frequency characteristic and the determined magnitude characteristic. This enables frequency response characteristics within a synchronous area of the electric power grid to be easily determined.

    摘要: Methods, apparatus and computer programs for transmitting and/or receiving information are described. Information encoded in a carrier signal comprising a modulation pattern superimposed on a grid frequency at which electricity flows in a synchronous area of an electric power grid, is decoded by measuring, at a receiving device, a characteristic relating to a frequency of electricity flowing in the electric power grid, accessing data indicative of one or more predetermined code patterns and performing a correlation process to determine a correlation between the modulation pattern and one of the one or more predetermined code patterns. The information is decoded on the basis of the determined correlation. This enables information to be easily transmitted within a synchronous area of the electric power grid.

    摘要: Methods, systems, and devices for controlling electrical energy consumption in an electricity distribution network, so as to reduce net energy consumption in a given area during a given time period, are described. In particular, a method of controlling electrical energy consumption within an electricity distribution network is described. The method comprises maintaining a database of information about electric devices, and identifying a time period during which consumption of electrical energy is to be controlled. The method further comprises selecting, based on device profile information stored in the database, groups of electric devices, and associating one or more time intervals with each of the selected groups. Requests are sent to the electric devices of the selected groups to control electrical energy consumption and/or provision by the electric devices. This enables a reduction in net consumption of electrical energy during a respective time interval.

    摘要: Apparatus and methods for determining an inertia characteristic of a synchronous area of an electric power grid are described. First data is determined. The first data represents a signal comprising a first variation in the grid frequency over a period of time, the signal resulting from a second variation, the second variation being a variation in provision of electric power to and/or consumption of electric power from the grid, the signal having been filtered according to a first filter defining a first frequency band to at least attenuate frequencies outside of the first frequency band. Second data is determined. The second data is representative of the second variation on a second frequency band, the second frequency band being substantially the same as the first frequency band. An inertia characteristic of a synchronous area of the electric power grid is determined based on the first data and the second data.
