Patent ID: 8458101

Claim:
A method for configuring installation capacities of a hybrid energy generation system which includes a plurality of power systems, for generating at least one combination of installation capacities which is respectively associated with the power systems, comprising: (a) an installation capacity configuration system, including a processing unit, an input unit and an environment detecting unit, the installation capacity configuration system being introduced to configuring the installation capacities associated with the power systems in the hybrid energy generation system, wherein the processing unit calculates a plurality of capacity coefficients and a plurality of maximum installation capacities respectively corresponding to the power systems according to at least one environmental parameter detected by the environment detecting unit, wherein the capacity coefficient is a ratio of an actual generated power to an ideal generated power of ta corresponding power system (b) the processing unit of the installation capacity configuration system evaluating the combination of installation capacities according to a total power requirement, the maximum installation capacities, and the capacity coefficients, wherein the total power requirement is a contract capacity, an over-contract capacity, or a value which is set according to a user's requirements (c) the processing unit of the installation capacity configuration system calculating a system cost of the hybrid energy generation system; (d) the processing unit of the installation capacity configuration system calculating a recovery cost due to using the power generated by the hybrid energy generation system; (e) the processing unit of the installation capacity configuration system calculating a recovery period according to the system cost and the recovery cost, wherein the recovery period represents the time when the system cost is equal to the recovery, cost; and determining whether an expected recovery period according to the user's requirement is larger than the recovery period or not, if the expected recovery period is smaller than or equals to the recovery period, go back to step (b); and (f) the installing capacity configuration system determining whether all combinations of the installation capacities are evaluated or not, when if there is the combination which is not evaluated, the method then goes back to step (b) by the processing unit of the installation capacity configuration system evaluating the combination which is not evaluated, when all combinations are evaluated already, the combination of installation capacities with minimum recovery period is deemed as the optimized configuration of the hybrid energy generation system.
