TITLE: Optimal sizing of a stand-alone hybrid power system via particle swarm optimization for Kahnouj area in south-east of Iran | |
Abstract—
In this paper a novel intelligent method is applied to the problem of sizing in a hybrid power system such
that the demand of residential area is met. This study is performed for Kahnouj area in south-east Iran. It
is to mention that there are many similar regions around the world with this typical situation that can be
expanded. The system consists of fuel cells, some wind units, some electrolyzers, a reformer, an anaerobic
reactor and some hydrogen tanks. The system is assumed to be stand-alone and uses the biomass as
an available energy resource. In this system, the hydrogen produced by the reformer is delivered to the
fuel cell directly. When the power produced by the wind turbine plus power produced by the fuel cell
(fed by the reformer) are more than the demand, the remainder is delivered to the electrolyzer. In
contrast, when the power produced by the wind turbine plus that produced by the fuel cell (fed by the
reformer) are less than the demand, some more fuel cells are employed and they are fed by the stored
hydrogen. Our aim is to minimize the total costs of the system such that the demand is met. PSO
algorithm is used for optimal sizing of system’s components.
