Summary The desire to integrate more renewable energy into the electrical grid necessitates an evolution in its architecture. This evolution will shift grid generation sources from centralized to decentralized production, facilitating and distributing the placement of renewable and intermittent generation sources across the grid. However, this decentralized integration raises a number of issues, notably the use of power electronics to facilitate access to these energy sources while simultaneously providing grid services. This thesis initially focuses on a pair of converters designed to address this grid

 evolution and to perform potentially necessary grid services. This pair of converters is termed an energy router due to the grid services it offers.

 Summary 

 The rapid development of converter-based devices such as converter-interfaced renewable generations and high-voltage direct-current (HVDC) transmission links is causing a profound change into the very physics of the power system. In this scenario, the power generation is shifted from the pollutant synchronous generators based on nuclear or fossil fuels to converter-based renewable resources. The modeling, control, and stability of the power converters are now one of the focuses of attention for researchers. Today, power converters have the main function of injecting power into the utility grid, while relying on synchronous machines that ensure all system needs (eg, ancillary services, provision of inertia and reliable power reserves). This operation mode of power converters is called "Grid-following". Grid-following converters have several limitations, such as: inability to operate in a standalone mode, stability issues under weak grids and faulty conditions and also, negative side effect on the system inertia. To tackle these challenges, the grid-forming control as an alternative has shown its appropriate performance that could make this kind of control a promising solution to respond to the system needs and to allow a stable and safe operation of power system with high penetration rate of power electronic converters. In this thesis, a fundamental description of grid-forming control with a simplified quasi-static modeling approach aiming to regulate the converter active power by a voltage source behavior is presented. From the description, several variants of grid-forming strategies are identified that represent some differences in terms of active power dynamic behavior, inertia emulation capability and system frequency support. Hence, the presented grid-forming variants are then classified according to their capabilities/functionalities.

The Theory Of Electromagnetic Field by K. Polivanov; P Ivanov (translator) 

The theory of an electromagnetic field is a concluding subject in the curriculum of the theoretical training of electrical engineers. The field theory course usually follows the course in the basic theory of electric circuits. The author covers the basic aspects of the theory of an electromagnetic field within the restricted space so that the text can fit the interest of students and answer the practical engineering needs. The emphasis therefore is on the behavior of fer­ romagnetic bodies in an electromagnetic field and on the processes in real imperfect dielectrics and poor conductors. The text also gives strict definitions of the basic vec­ tors and shows the differences between them. Many of the aspects discussed in the book focus on the problems one has to deal with in electrical engineering practice. This is one of the factors that influenced the organization of the book and the manner of presentation of the material. A similar treatment of the field theory was also given in the book by A. Netushil and K. Polivanov The Theory o f Electromagnetic Field. Theoretical Principles o f Elec­ trical Engineering. Part 3 (Gosenergoizdat, in Russian). No effort has been made to cite a great number of contributors in this area. In the author's opinion, of many valuable texts, the following books will be very helpful to students in the study of the theory of electrical engineering: Analysis and Synthesis o f Electric Circuits (Mir Publishers) by G. Zeveke, P. Ionkin, A. Netushil, and S. Strakhov, The Feynman Lectures on Physics (Addison-Wesley) by R. Feynman, R. Leighton, and M. Sands, Electricity and Magnetism (McGraw-Hill) by E. Purcell that treats the effects of moving bodies in an electromagnetic Field, and Fundamentals o f the Theory o f Elec­ tricity (Mir Publishers) by I. Tamm.
