Comparison of Control Optimization Approaches for Low Exergy Heating And Cooling Systems | 2015 | English
The paper focuses on control optimization of nonlinear system models where the differential-algebraic equations are formulated in Modelica.
In previous studies, the authors combined load shifting and Model-based Predictive Control (MPC) for the optimization of a HVAC system.
This research aims to define a modelling approach to simulate District Cooling Systems (DCS). A model of the network has been developed using the equation-based object-oriented language Modelica.
