Abstract
Systems and methods are disclosed that operate to correct the electrical characteristics of an electric distribution system based on analysis at a particular point in the system, for example, at a customer's meter. To do so, the subject characteristic may be measured at the meter. The subject characteristic may be provided to a power inverter controller, which responds by modifying the characteristic of the inverter output to achieve the desired measurement at the meter.
Claims15
A power inverter system, comprising:
- a plurality of controllers, each capable of generating signals based on an analysis of current measured electrically proximate to a respective plurality of meters, each being on an electric distribution grid to which it is individually operatively connected by a grid power line, and each being individually coupled via a load power line to a load corresponded to each of the plurality of meters;
- a power inverter corresponded to each of the plurality of controllers, comprising:
- a power input for receiving DC power;
- a signal input for receiving signals from the controller;
- a power output for providing AC power to at least one of the load and the electric distribution grid;
- a voltage converter for converting a voltage level of the DC power to an effective voltage level of the AC power;
- a current converter for converting a current of the DC power to an effective current of the AC power;
- and
- a plurality of components electrically responsive to the signals received from the controller,
- wherein the power inverter corresponded to each of the plurality of controllers is controlled by a wireles sly-communicative combination of the plurality of controllers to regionally balance at least a power factor across the plurality of meters by balancing individual ones of the power inverters within a particular region, as indicated by individual ones of the plurality of meters, against each other.
