Abstract

To supply the campus site of the Technische Universitat Munchen at Garching with a significantly varying demand of heat and power a Cheng Cycle gas turbine cogeneration plant was installed. By injecting steam, produced by the heat recovered from the exhaust gases of the gas turbine, the electricity output can be increased by 50 % from 4 to 6 MWe within 2 minutes. To make full use of this flexibility an online load control system is essential. The combination of offline optimization by MILP-calculations and conversion with a neural controler during operation has proven as a simple but effective way to realize such a system.
