A METHOD AND SYSTEM FOR MANAGING AN ELECTRICAL LOAD OF A USER FACILITY BASED ON LOCALLY MEASURED CONDITIONS OF AN ELECTRICITY SUPPLY GRID

摘要

The present invention relates to a method of managing the consumption and distribution of electricity in a user facility, wherein the user facility is connected to an electricity supply grid and the user facility comprises a grid connected on site generator; the method comprising the steps of measuring waveform conditions on a portion of the electricity supply grid adjacent the user facility to obtain locally measured waveform conditions; measuring electrical power readings from the on site generator; communicating the locally measured waveform conditions and the electrical power readings to a controller in the user facility; determining, at least on the basis of the locally measured waveform conditions, whether the electricity supply grid is oversupplied or undersupplied with electricity; and, modifying the flow of the electricity within the user facility based on whether the electricity supply grid is oversupplied or undersupplied with electricity and/or the electrical power readings from the grid connected on site generator.
