Coalesced Gas Turbine and Power System Modeling and Simulation using Modelica

Abstract

This work reports how the multi-domain physical modeling and simulation Modelica language has been employed to create a benchmark power grid and gas turbine model within the ITEA3 OpenCPS project. The modeling approach is not only shown to be useful to test the functionalities of the OpenCPS toolchains, but it also could give rise to potential applications in power system domain studies where the widely-accepted turbinegovernor models are not rich enough to represent the multi-domain system dynamics.

Review on Water and Energy Integration in Process Industry: Water-Heat Nexus

“…Applicable for scenario analysis, sensitivity analysis and further API-based integration with optimisation models. The unit operations simulation models included in WEIS may be developed overall using existing software packages and modelling languages, such as Modelica [221][222][223][224][225][226][227], TRNSYS [228],…”

“…The technologies/measures being simulated include hot air recycling as combustion air, the implementation of heat exchangers for water/air preheating, organic Rankine cycles, multi-effect distillation units and PCM heat exchangers.

Automatic Re-synchronization Controller Analysis within a Multi-Domain Gas Turbine and Power System Model

“…The multi-domain modeling approach was discussed and suggested for the modeling of the power grid in [5] [9] validates the idea to use Modelica language for complex energy systems modeling without any loss of information, however, that work does not report any control system design for turbine and governor system. The work presented in [5] also shows that the multi-domain modeling approach is essential for power system analysis when gas turbines are used to provide grid flexibility and this is especially important for controller system design. The work presented by the authors in [4] reports the re-synchronization control architecture used herein, which was analyzed only using component models from the power system domain.…”

“…The turbine model requires speed, electrical power and the governor's output to calculate the desired output mechanical power. Meanwhile, in the multi-domain model in [5], the turbine model output is mechanical power (Pmech) and the input is the fuel flow (WF). In steady-state, the mechanical power produced by the turbine is therefore described by…”

“…Reference [5] describes in detail the differences between the simple turbine model (GGOV1) and multi-domain model. The multi-domain model is composed of a single shaft gas turbine using components from from ThermoPower and a governor model from the OpenIPSL.…”
