<p>Embodiments of the invention relate to methods and systems for measuring and/or managing power consumption by power units connected to an electricity distribution network. Conventional electrical power flow measurement methods use meters such as "smart meters", which are typically located at the premises of a consumer or provider of electrical power, and measure the total power consumption and/or provision by all power units at the premises, meaning that power flows relating to individual devices located at the premises, or groups of devices distributed across multiple premises, cannot be easily measured. In a method according to an embodiment of the present invention, power flow to and/or from a power unit connected to an electricity distribution network is controlled in accordance with a control sequence, such that the consumption and/or provision of power by the power unit results in a power flow having a predefined flow pattern, and having a characteristic, such as an amplitude, which can be remotely measured. This measurement may be performed using a method according to an embodiment of the present invention, in which a signal indicative of power flowing at a measurement node is measured and correlated with a predefined pattern, and a characteristic of the correlated signal is measured. Thus, in embodiments of the present invention, power flow characteristics resulting from a group of one or more power flow devices can be remotely detected and measured.</p> |
