Abstract
Operation methods and systems for distributed generation from a plurality of generators, and computer readable media. One method comprises the step of applying a forward looking matching algorithm to determine a matching matrix with elements mi,j denoting the fraction of generator i's predicted supply assigned to respective load j of a plurality of loads such that a probability of meeting each load's associated power demand characteristic in a next supply cycle satisfies a threshold criterion.

An operation method for distributed generation from a plurality of generators, the method comprising the steps. of:
- determining, using a forward looking matching algorithm, a matching matrix with elements mij denoting the fraction of generator i's predicted supply assigned to respective load j of a plurality of loads such that a probability of meeting each load's associated power demand characteristic in a next supply cycle satisfies a threshold criterion;
- and
- distributing power from the plurality of generators to the respective loads in accordance with the matching matrix, wherein:
- the loads comprise different sets of one or more loads each, the loads of each set having at least one load characteristic in common, wherein the different sets of loads have different associated priorities;
- and wherein:
- a first set comprises one or more loads having a predetermined percentage of their power demand to be supplied from the plurality of generators;
- a second set comprises one or more loads having a predetermined amount of power from the plurality of generators to be supplied to them;
- a third set comprises one or more loads having a predetermined percentage of energy from one or more specified ones of the generators to be supplied to them;
- and
- a fourth set comprises one or more loads having a flexible amount of energy from the plurality of generators to be supplied to them.
An operation system for distributed generation from a plurality of generators, the system comprising a processing unit configured for applying a forward looking matching algorithm, wherein the algorithm is configured to determine a matching matrix with elements mij denoting a fraction of generator i's predicted supply assigned to respective load i of a plurality of loads such that a probability of meeting each load's associated power demand characteristic in a next supply cycle satisfies a threshold criterion, and wherein a probability of meeting an associated power demand characteristic of each one of a plurality of loads satisfies the threshold criterion, and the processing unit is further configured for sequentially admitting one or more additional loads having respective associated power demand characteristics when a surplus of the distributed energy generation is determined while satisfying the threshold criterion, wherein the processing unit is further configured for adding one or more additional generators and repeating application of the matching algorithm, and wherein:
- the loads comprise different sets of one or more loads each, the loads of each set having at least one load characteristic in common;
- a first set comprises one or more loads having a predetermined percentage of their power demand to be supplied from the plurality of generators;
- a second set comprises one or more loads having a predetermined amount of power from the plurality of generators to be supplied to them;
- a third set comprises one or more loads having a predetermined percentage of energy from one or more specified ones of the generators to be supplied to them;
- and
- a fourth set comprises one or more loads having a flexible amount of energy from the plurality of generators to be supplied to them.
