About this book This book presents a comprehensive set of guidelines and applications of DIgSILENT PowerFactory, an advanced power system simulation software package, for different types of power systems studies. Show all. Pages In particular, the impact of ambient conditions on unit rating, the temperature control system, gas turbine compressor intake, and associated components such as inlet guide vanes IGVs must be accurately modelled, particularly when operating at high output, in order to accurately assess the impact of CCGTs on stability issues.
In addition, modelling of an open cycle gas turbine OCGT will be presented. Due to its variable nature, the increasing penetration of wind power plants into power systems poses new challenges for reliable and secure operation.
Considering that model-based time-domain simulation constitutes a widely used approach for assessing the power system dynamic performance as well as for making proper decisions concerning operational and planning security strategies, there has been a great research effort, especially in the last decade, to cover different issues on modelling of wind generation systems WGS. Remarkably, the development of models that entail a compromise between accuracy and simplicity is one of the main concerns for enabling the simulation of large-scale systems.
The first one is the reduced third-order model of the doubly fed induction generator DFIG , for which suitable models for multiple point tracking, the rotor-side controller RSC , current controller, and speed and pitch controller are adopted. The second model constitutes a generic equivalent model, which can be used for representation of the stationary and dynamic response of wind power plants comprising several DFIGs. RMS-type simulation results are presented to illustrate the suitability of the adopted modelling approaches.
Korai, Jaime C. Modal analysis, or small-signal stability analysis, refers to the ability of a system to withstand small perturbations around an equilibrium point without reaching instability or displaying sustained oscillations.
This is an important problem in real systems as sustained oscillations may cause mechanical failures in generating units and make the system vulnerable to the point of losing stability.
In order to define the most critical scenario, the standard approach employed by the industry is to consider the system at its maximum loading. This chapter proposes that critical scenarios should be further sought as in even lighter loading conditions, low-frequency oscillations may dangerously appear. Using DPL, the system modal analysis is parameterized in order to search for critical operating points. To validate the importance of employing a parameterized modal analysis, a real case is studied: The obtained results applying parameterized modal analysis show that the system in a real operation only requires minor deviations from the programmed operating points to incur in dangerous low-frequency oscillations.
These results validate the importance of searching for critical scenarios and DPL scripting is used to program the steps of the proposed analysis. The scripts and applications presented in this chapter set the basis for additional development to identify critical scenarios for modal analysis in other real systems. The use of probabilistic framework is of great importance for the development of comprehensive approaches, which are suitable for coping with increasing uncertainties in power system operation and planning.
While huge effort has been put in the past into the conception of probabilistic methods to deal with stochastic load flow calculation, there is an increasing interest on the development of new approaches to ascertain the implications of changing operating conditions in terms of power system dynamic performance. Among the main concerns on this regard is the determination of the degree of exposure to poorly damped low-frequency oscillations LFOs , which occur typically in the range of 0.
The chapter also illustrates the implementation of the PST 16 benchmark system, which has a relative large size, and is appropriated to study different kinds of stability problems, especially LFOs. Numerical experiments performed on this system support the relevance of the MC-based approach. Korai, Francisco M.
The development and application of heuristic optimization algorithms have gained a renewed interest due to the limitations of classical optimization tools for tackling several hard-to-solve problems in different engineering fields. Due to the complex nature of power system dynamics, electrical engineering optimization problems usually present a discontinuous multimodal and non-convex landscape that necessarily has to be handled by heuristic optimization algorithms.
While most of the pioneer heuristic optimization approaches, such as genetic algorithms , particle swarm optimization , and differential evolution , are undergoing different types of modifications and extensions in order to improve their performance, great focus is also being put into the development of new approaches aiming at conceptual simplicity, easy adaptability for a variety of optimization-based applications, and outstanding performance.
The mean—variance mapping optimization MVMO is a recent contribution to the family of evolutionary optimization algorithms. Its novel search mechanism performs within a normalized range of the search space for all optimization variables and follows a single parent—offspring pair approach.
Besides, MVMO is characterized by a continuously updated knowledge archive storing the n-best solutions achieved so far, from which a special mapping function, which accounts for the mean and variance of the optimization variables, is applied for mutation operation.
In this way, the algorithm proceeds by projecting randomly selected variables onto the corresponding mapping function that guides the solution toward the best set achieved so far. Despite the orientation on the best solution, the algorithm keeps on searching globally. An exemplary application on the coordinated tuning of power system supplementary damping controllers is presented and discussed in order to highlight the feasibility and effectiveness of structuring MVMO-based applications in DIgSILENT PowerFactory environment.
Jaime C. Simulation tools are the most economical solution for modelling and design of various components of large-scale power systems. However, as the complexity in the integrated electric power network grows, the need for more comprehensive simulation tools rises. Modern simulation tools have therefore been developed in line with this ever increasing need by means of integration of improved user interfaces. Two study cases will be presented in this chapter.

Alamuti, F. Li, G. Taylor, M. In this chapter, some principles of simulation automation are explained, which are helpful for investigating a large number of simulation scenarios. Parameters of data models often need to be changed for a certain range or results need to be post-processed. An example project shows the implementation of a local voltage controller by utilising the scripting language. Simulation parameters are taken from Microsoft Excel for parametric studies and results are stored back into the spreadsheet.
Various possibilities exist to interface the power system model and simulation engine of PowerFactory. These interfaces open applications for co-simulation, real-time simulation for controller hardware-in-the-loop HIL set-ups or automation and control of simulation.
Rapid prototyping and validation of power system controllers have always been a challenge. Thus, rapid prototyping and validation of new complex control systems require testing with extensive set of test cases involving a multitude of power system components. The numerous types of variable involved, such as topology, energy flow, fault conditions, autonomous control systems, and protective device operation, most of which are stochastic in nature, naturally compound the problem of prototyping and validation.
