Matlab/Simulink toolbox for RMS simulations of power systemsby Regelungssysteme und Netzleittechnik

The current changes in power networks induced by the energy transition and the introduction of power electronic technologies had made necessary the study of such systems in a dynamical manner. Contrary to standard steady state and power flow analysis, now it is required to simulate the transient behavior of the networks with a particular interest on the response of the different elements’ controllers. One of the limitations in dynamic simulation of power systems is the lack of software tools specialized in both, power systems and automatic control. This is the case of PowerFactory, where the standard tools for power system analysis and simulation are available, but the incorporation of sophisticated control algorithms is rather difficult and obscure. On the other hand, one has Matlab/Simulink, designed to simulate complex control systems, but which lacks tools for simulation of large power networks.The purpose of the thesis is to dote Matlab/Simulink of elements for simulating transmission and distribution networks. These networks are usually simulated by neglecting the transient response of transmission lines and passive elements such as transformers, and only considering dynamical behavior in a time scale of tens of milliseconds or above. The process is usually referred as RMS-simulations. For that, the main tool would be Simscape, where the idea is to implement algebraic models of balanced and unbalanced three-phase impedances, admittances, transformers, ZIP loads, and compatible dynamical models of synchronous generators, induction motors and composite loads.
