Comparative Economical Analysis of a Small Scale Trigenerative Plant: A Case Study

In this paper a mixed integer linear model is proposed to solve the problem of the optimal energy management of a system composed by several kind of loads (electrical, thermal, cooling) and energy sources (external network, CHPs, boilers, chillers). The optimizer manages on/off status of CHPs and boilers and their level of power production and power rate of chillers. A realistic scenario of trigenerative plant is studied focusing the attention to the economical analysis of different CHP size.
