Abstract
Methods and systems for measuring and/or managing power consumption by power units connected to an electricity distribution network are disclosed. 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 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, power flow characteristics resulting from a group of one or more power flow devices can be remotely detected and measured.
