Popis: An optimal unit sizing method is developed for hybrid power generation systems utilizing photovoltaic and wind energy. Equipment capacities and electric maximum demand are determined so as to minimize the annual total cost and annual energy consumption from the viewpoints of economy and energy conservation, respectively. This optimization problem is considered as a multiobjective one, and a discrete set of Pareto optimal solutions is derived numerically using the weighting method. Two systems interconnected with the electric power grid are inventigated : one has the option of reverse power flow into the grid, and the other, no option. By carrying out some case studies, the trade-off relationships between the two objectives are clarified, and optimal values of equipment capacities are determined. The effect of electricity deficit on unit sizing is also investigated.
