“…A highly complex process like this needs a sophisticated control strategy that integrates both processes in a joint approach. A first step in that direction is taken by Gottelt et al 30 using the models presented in this paper. The authors implement a model-based control strategy based on existing directives and extend it to be also used for power plants with postcombustion CO 2 capture.…”

The combined operation of postcombustion CO 2 capture and a power plant is a complex process with significant mutual interactions. Although the application of CO 2 capture imposes an efficiency penalty on the power plant, it also provides the opportunity to operate the power plant in a more flexible way. To analyze this process, a detailed model of a postcombustion capture plant is developed and validated with measurement data. Afterward, the model is coupled to the model of a hard coal-fired power plant to study the effects of a joint operation. In a case study scenario, the steam extraction of the carbon capture plant is reduced by 50% to increase the power generation of the power plant. The results indicate that it is possible to provide primary frequency control by using this mode of operation.

“…This is an open source software available on openmodelica's website for free of cost. This is an objectoriented, equations-based modeling tool containing more than a hundred inbuilt libraries and a well number of external libraries that can be downloaded from github website [8]. This tool combines a graphical user interface with the model and is useful in modeling complex physical systems with mechanical, electrical and control sub-components [7].…”

“…Although gas turbine power system is a stable form of electrical energy but the problem comes with the efficiency of the system which is very low. Typical gas turbine efficiencies are between 20 to 25 percent and different hazardous gases like CO2 and NOx are exhausted into the atmosphere, so there has always been a focus on the improvement of the efficiencies of thermal systems [8]. This endeavor brought us to a new technology in the thermal system known as CCPP (combined cycle power plant) [9].…”

With the integration of intermittent energy sources in the power system, the main focus of thermal power plant design is to optimize the conventional system by improving efficiency and flexibility of power generation in the start-up and base-load procedures. This paper focuses on the behavior of thermal power generation with respect to load variations, fuel variations, weather conditions and internal dynamics of the system to aid in energy planning and the optimization of power system. Dynamic modeling and subsequent simulation is to make improvements. Therefore, to model the system, this research study has used a dynamic modeling and a simulation framework (OpenModelica based on modelica language) which is an object-oriented and equation-based language. This framework allows a non-causal modeling and a flexible reuse of the models since data-flow direction is not predefined like other state of the art simulating tools i.e. MATLAB. The proposed model analyses the trend of electrical power generation of KOT ADDU thermal power plant to predict the future demand of electrical power. The achieved results show more than 90% accuracy of the proposed model in the transient operation such as start-up and base load procedure.

Within the DYNCAP project, the Modelica library ClaRaCCS is being developed. This library will provide a framework to model both steam power plants and carbon capture units in an integrated manner. The current status of the library is presented. The structure of the library and the general model design is outlined. Its user-friendly handling as well as its high flexibility in the modelling of individual complex scenarios are demonstrated by the concrete modelling of a furnace. The scenario of a closed steam cycle coupled to a carbon capture cycle based on an amine gas treatment is described and simulation results are briefly discussed.
