Energy saving in Airports by trigeneration - Part II: Short and long term Planning for the Malpensa 2000 CHCP Plant

With reference to the feasibility analysis for CHCP applications in airports performed in Part I of this work, the optimal strategy forrepowering and operation of the Malpensa 2000 CHCP plant is here discussed. The analysis starts from experimental energy demanddata, available on hourly basis for an entire operational year. After a description of the CHCP lay-out, the optimal management strategywas determined keeping into account the articulated energy tariff system and the technical characteristics of components. A profit-orientedoptimization of the repowering actions to take up to 2010 is presented, based on the expected growth of energy consumption due tothe scheduled increases in transportation capacity; energy and emission saving were also calculated by simulating plant operation onhourly basis, for several repowering strategies.
