Abstract
Abstract A load control for a system comprised of a plurality of energy converters wherein increases in total energy demand from the system is compensated by increasing only the rate of energy conversion of that converter producing energy conversion at least cost and decreases in total energy demand from the system is compensated by decreasing only the rate of energy conversion of that converter producing energy conversion at highest cost.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
A load control for a system comprised of a plurality of energy converters, comprising, a first means generating a System Control Signal corresponding to system load, means generating signals corresponding to the cost of production of each of said plurality of converters, means selecting the least cost signal from among said last named signals, means generating output signals during an increase in the System Control Signal and means under the control of the System Control Signal and said output signals permitting said System Control Signal to increase the rate of production of the converter having lowest cost of production while inhibiting a change in the ratio of production of the other converters in said plurality of converters to thereby maintain equilibrium between the total rate of energy conversion by said plurality of converters and demand.
Claim 2
Dependent Claim
135 words
A load control for a system comprised of a plurality of energy converters, comprising, a first means generating a System Control Signal corresponding to system load, means generating signals corresponding to the cost of production of each of said plurality of converters, means selecting the least cost signal from among said last named signals, means generating output signals during an increase in the System Control Signal and means under the control of the System Control Signal and said output signals permitting said System Control Signal to increase the rate of production of the converter having lowest cost of production while inhibiting a change in the ratio of production of the other converters in said plurality of converters to thereby maintain equilibrium between the total rate of energy conversion by said plurality of converters and demand.
Claim 3
Dependent Claim
81 words
A load control as set forth in claim 1 further including means under the control of said output signals and said System Control Signal during decreases in the System Control Signal to decrease the rate of production of the converter having the highest cost of production while inhibiting changes in the rates of production of the other converters in said plurality of converters to thereby maintain equilibrium between the total rate of energy conversion by said plurality of converters and demand.
Claim 4
Dependent Claim
19 words
A load control as set forth in claim 2 wherein each of said energy converters is a vapor generator.
