Abstract
A linear multi-objective model for power generation expansion is studied in this paper. The model is applied to the power system planning of Singapore and solved by a newly developed interactive method. The generation alternatives considered are oil-fired, coal-fired, natural-gas fired and nuclear power plants. The multi-objective model does not recommend nuclear plant for Singapore because of the high risks and environmental impact, though the single objective version considers it attractive for economic reasons. Results obtained are analyzed and some preferred expansion plans for Singapore are recommended.
