In this paper a PI based adaptive control system is developed to control an organic Rankine cycle power plant. In particular, the control of the turbine speed during the transient between the normal operation mode of the system (connected to the grid) and the islandmode (connected to a stand-alone load) is of main concern. A control algorithm suitable for the implementation on a programmable lo...

The Organic Rankine Cycle (ORC) heat engine constitutes a very promising technology to recover waste heat (for instance from industry or from internal combustion engines) but also to exploit renewable energy sources (such as solar, biomass or geothermal energy). This seminar will emphasize how modeling and simulation tools could be used during the design stage of an ORC system in order to best ...

In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production. A proton exchange membrane (PEM) is also used for hydrogen production and the domestic water heater is used for heating. The impacts of some design parameters, suc...
