Title:
Development of a non-linear state estimator for advanced control of an ORC test rig for geothermal application 
Abstract:
Organic Rankine Cycle systems are increasingly installed in low-enthalpy geothermal plants to supply efficiently heat and power. The variation in heat demand and the possible contribution to grid ancillary services result in part-load operation and flexibility challenges for the ORC. A suitable control system, able to maximize the power output and guarantee high profits, can be achieved by state-based multivariable advanced controllers. These are based not only on the error on the controlled var...    »
