Optimal generation evaluation using SAW, WP, AHP and PROMETHEE multi - criteria decision making techniques

In the present day scenario the energy demand is going on increasing. It is expensive to import electricity from the generation far from load centers because of the cost of power loss. It is therefore more economical to use electricity generated by local distributed generators. In this paper power generation from wind, Combined Heat Power (CHP) and utility for a complete day is considered. This paper discusses different methods like Simple Additive Weighting (SAW) method, Weighted Product (WP) method and Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) multi-criteria decision making technique to evaluate the optimal generation of a particular day. The Analytic Hierarchy Process (AHP) method is used to verify the weights´ selections. The results obtained by the multi-criteria evaluation using the presented methods, gives the possibility of identification and evaluation of the optimal generation in a particular day.
