GRID TIED, REAL TIME ADAPTIVE, DISTRIBUTED INTERMITTENT POWER

摘要

A method for predicting the reactive power needs (or other power characteristic needs) for a plurality of customer circuits on an intermediate circuit operably connected to the grid by averaging measurements of utility power characteristics (such as power factor, frequency, and voltage) from a plurality of energy management controllers (or other measuring devices) connected to said customer circuits so that the utility or other grid participant can tailor its power output to meet active and reactive power needs (or other power characteristic needs) to improve transmission efficiency, increase capacity and avoid voltage fluctuations.

1. A method for managing, on a grid operably connected to a grid participant, power factor of an intermediate circuit having operably connected customer circuits with varying active and reactive loads behind customer utility meters, wherein said customer circuits are connected at common connections to said intermediate circuit, comprising:
providing energy management controllers to a connected plurality of said customer circuits to autonomously controllably switch or vary in real time controlled active and reactive load portions of said customer circuits, by autonomously connecting or disconnecting or varying said controlled active and reactive load portions in real time, whereby the controllers allow control of said power factor of said connected plurality of customer circuits in real time behind the utility meter;
wherein said controllers are downloadably connected to said grid participant so that said grid participant can download to the controllers grid participant rules for said grid participant's desired outcome for said intermediate circuit;wherein said controllers obtain measurements of power factor and power consumption of said connected plurality of customer circuits at said common connections in real time;wherein each of said controllers is uploadably connected to said grid participant so that said grid participant can upload said measurements of power factor and power consumption of said connected plurality of customer circuits; weighting said measurements of power factor by power consumption and then averaging to provide a weighted averaged measurement of power factor for said customer circuits of said connected plurality of said customers; downloading to said controllers said weighted averaged measurement of power factor for said connected plurality of said customers; wherein, in real time response to said weighted averaged measurement of power factor falling outside desired ranges, said controllers in a customer's customer circuit autonomously connect and disconnect and vary said controlled active and reactive load portions to adjust said power factor of that customer circuit in real time behind said utility meter to contribute to meeting said grid participant rules, if said grid participant rules require, based on said weighted averaged measurement.
