Trigeneration system planning based on decision theory

Energy system planning is a multi-year process with significant uncertainty embedded in the variables affecting the planning decisions. This large uncertainty calls for the adoption of techniques of analysis based on the definition of suitable scenarios and of their probability of occurrence indicated by the decision-maker. This paper addresses trigeneration system planning by applying a decision theory-based approach, considering the net present cost as economic indicator. The application of this method shows the convenience of setting up a combined generation system to serve the simultaneous demand of electricity, heating and cooling loads.
