Abstract

The present invention encompasses a control system and method for systems of producing and consuming units. The method of the invention includes the steps of setting each producing unit to have an output responsive to an analog signal representative of a market price, and connecting each producing unit to a marketwire, with the changes in the analog signal on the marketwire representing changes in the market price resulting from inputs from the consuming units and the output response of each producing unit.

Claims

1. A control method for non-linear coupled systems of producing units having a single consumer output, the method comprising the steps of

setting each producing unit to have an output responsive to a continuously provided analog signal representative of a market price,

connecting each producing unit to a marketwire carrying the analog signal, with the changes in the analog signal on the marketwire representing changes in the market price and dependent upon the output response of each producing unit.

2. A control method of claim 1, wherein the analog signal is electrical.

3. The control method of claim 2, wherein the electrical analog signals on the marketwire are represented by voltage levels and changed by varying the voltage levels in the marketwire.

4. The control method of claim 2, wherein the electrical analog signals on the marketwire are represented by current levels and changed by varying the current levels in the marketwire.

5. A control method for systems of interconnected producing units and consuming units, the control method comprising the steps of

providing producing units connected to a marketwire, the producing units having an output responsive to a market price determinable directly from a signal carried by the marketwire,

providing consuming units connected to the marketwire, the consuming units having an input responsive to the market price determinable directly from the signal carried by the marketwire, and

equilibrating electrical characteristics on the marketwire based on input/output from the producing units and the consuming units to determine the market price.

6. The control method of claim 5, wherein the electrical characteristic equilibrated is voltage level in the marketwire.

7. The control method of claim 5, wherein the electrical characteristic equilibrated is current in the marketwire.

8. A control method for systems of interconnected producing units and consuming units, the control method comprising the steps of

providing producing units connected to a marketwire, the producing units having an output responsive to a market price determinable directly from a signal carried by the marketwire,

providing consuming units connected to the marketwire, the consuming units having an input responsive to the market price determinable directly from a signal carried by the marketwire,

storing excess electrical energy in an inventory unit as necessary to equilibrate electrical characteristics on the marketwire based on input/output from the producing units and the consuming units to determine the market price.

9. The control method of claim 8, wherein the electrical characteristic equilibrated is voltage level in the marketwire.

10. The control method of claim 8, wherein the electrical characteristic equilibrated is current in the marketwire.
