Frequency domain (FD) methods for electromagnetic transient analysis of electric power systems offer outstanding simplicity and accuracy when dealing with distributed parameter elements and components that exhibit frequency-dependent behavior. However, the use of FD methods is usually restricted to the simulation of small and simple networks, since it is commonly believed that their application implies a very large computational burden when compared to time domain methods. This study demonstrates that FD methods can accommodate the detailed simulation of large distribution networks within acceptable computer times and in a very straightforward manner, thus offering an attractive complement or alternative to common time domain tools. For this purpose, the basic methodology and guidelines for the frequency domain modeling of the most common components of distribution systems are described in detail, as well as a general approach for network construction, reduction, and solution. The elements considered include overhead lines, underground cables, transformers, circuit breakers and loads. As an added advantage of FD methods, the application of network equivalent techniques for the reduction of large systems is considerably simpler than in time domain, as shown in this study. This is particularly valuable for the simulation of distribution systems given their size and complexity. Initially, transmission line, underground cable, and transformer models are implemented separately for verification purposes. In addition, a simplified distribution network and a test feeder from IEEE (13-bus) are constructed to demonstrate that the network reduction technique does not imply any loss of accuracy, and it also provides very similar results when compared with the complete network implementation in Electromagnetic Transient Type Program-Alternative Transients Program (EMTP-ATP). Then, 3 test cases corresponding to larger distribution systems are simulated. They correspond to IEEE test feeders with 34 and 123 nodes and a synthetic system with 1188 nodes emulating a densely meshed urban distribution network. These cases demonstrate the generality of the methodology and the ability of the network reduction to simplify the system and efficiently reduce the computational burden in the simulation of large systems.

The simulation of electromagnetic transients is a mature field that plays an important role in the design of modern power systems. Since the first steps in this field to date, a significant effort has been dedicated to the development of new techniques and more powerful software tools. Sophisticated models, complex solution techniques and powerful simulation tools have been developed to perform studies that are of supreme importance in the design of modern power systems. The first developments of transients tools were mostly aimed at calculating over-voltages. Presently, these tools are applied to a myriad of studies (e.g. FACTS and Custom Power applications, protective relay performance, simulation of smart grids) for which detailed models and fast solution methods can be of paramount importance. This book provides a basic understanding of the main aspects to be considered when performing electromagnetic transients studies, detailing the main applications of present electromagnetic transients (EMT) tools, and discusses new developments for enhanced simulation capability. Key features: Provides up-to-date information on solution techniques and software capabilities for simulation of electromagnetic transients. Covers key aspects that can expand the capabilities of a transient software tool (e.g. interfacing techniques) or speed up transients simulation (e.g. dynamic model averaging). Applies EMT-type tools to a wide spectrum of studies that range from fast electromagnetic transients to slow electromechanical transients, including power electronic applications, distributed energy resources and protection systems. Illustrates the application of EMT tools to the analysis and simulation of smart grids.

For the digital time-domain analysis of electromagnetic transients in an interconnected power system, the system is artificially divided into two sections: (i) the study zone, in which the transient phenomenon occurs and where the component models must be represented in detail, including physical and mathematical nonlinearities, and (ii) the external system which encompasses the rest of the network, and due to its electrical distance to the location of the transient phenomenon, can be represented by a linear network in the whole frequency range of interest. This thesis develops a new methodology to obtain a frequency dependent equivalent for an external network. The main motivation behind development of an equivalent for the external system is to minimize computation resources, i.e., CPU time and memory, for the analysis of realistic size systems. The required computational resources are the bottleneck in real-time simulation and application of off-line software packages for the analysis of high-frequency electromagnetic transients. The salient feature of the proposed approach, as compared with the other methods for deducing external network equivalent, is that it provides a simpler model (lower-order mathematical model) with the required accuracy. Furthermore, the proposed methodology ensures positive-realness of the equivalent. The proposed equivalent is referred to as the hybrid equivalent since it relies on a combination of (i) simplified distributed line models and (ii) lumped element models, to generate a frequency response equivalent of the external system. This thesis also expands the proposed approach to develop a multi-port equivalent and to consider the impact of sources (generators and harmonic sources) on the equivalent. The proposed concept has been applied to a realistic size interconnected 500 kV study system to obtain a single-port and a two-port equivalent with respect to pre-specified observation points. The validity and accuracy of the proposed approach is verified based on comparing the simulation results with those obtained from the simulation of the original system using the ElectroMagnetic Transients Program (EMTP).
