At first the approach of modeling depicts the independence of the AC and DC quantities and therefore two separate models - one for the AC and one for the DC side - can be figured out. The AC side model is developed in the dq frame out of the according differential equations. For the DC side no further transformation is required. Regarding the fact of balanced energy terms the two models can be merged. The consolidation of both models reveals a comprehensive large signal model of a multilevel based HVDC system which can be used for detailed analyses in power system stability studies. Due to the comparison of the generic stability model with an EMT (Electro-Magnetic Transient) HVDC model the consistence of the dynamic behavior is shown.

The purpose is the representation of system inertia, inter-area oscillations and primary control of large interconnected power systems by means of publicly available information. The approach to reach this target is based on a systematically developed load-flow model and the representation of system dynamics by means of standard dynamic models for generation units, their appropriate control and loads. The initial parameters of the standard dynamic models are tuned with regard to frequency measurements and published power system characteristics. The developed method allows general analysis of extensive influences on the dynamic behavior of a particular power system. Conceivable applications of the developed method are proposed for further system analysis. Finally an employment of the method is shown for the Continental Europe synchronous area (CESA).

Hence, a considerable number of bulk power transmission projects are going to be realized (e.g. [1]). Taking into account the recent technical development, three technologies are available for bulk power transmission: Direct current applications with voltage sourced or line commutated converters as well as the high-voltage AC technology up to 1200 kV. To select the most suitable technology for a particular project is often anything but trivial for the transmission system operator. Amongst other criteria, the influence on the electromechanical behavior of the power system is a decisive factor for network improvements that should be considered within the decision-making process. This paper aims at categorizing and analyzing this rather abstract term as a major criterion. The goal is to provide an indication, which factors are needed to be evaluated in advance of the well-considered choice. For that reason, several categories are introduced and thoroughly investigated within the scope of a theoretical approach. Where reasonable, simulation results are presented in order to enable the practical assessment of the impact on the electromechanical system behavior. As a conclusion, it is recommended to perform concise ex-ante studies with regard to the electromechanical dynamics as a decision-making basis to identify the most suitable transmission technology for a particular project. © 2015, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).

The model was developed by the European Network of Transmission System Operators for Electricity (ENTSO-E) working group System Protection and Dynamics 2 and the University of Erlangen-Nuremberg within a collaboration. The paper describes the DSM scope, input and necessary steps towards an adequate basis for the novel dynamic data enhancement process by means of standard dynamic models for generation units and allocation criteria. Through a parameter variation process the DSM has been successively tuned to match a frequency measurement of a system event with respect to system inertia, frequency containment reserve and one of the typical oscillation modes within Continental Europe. Finally, the DSM behavior has been verified by means of previous experience from operation.
