Control Electrical Machine Thesis

In this framework, we formulate a category of optimization problems, called optimal load control (OLC), to incorporate the goals of frequency control, such as balancing power supply and demand, restoring frequency to its nominal value, restoring inter-area power flows, etc., in a way that minimizes total disutility for the loads to participate in frequency control by deviating from their nominal power usage.

By exploiting distributed algorithms to solve OLC and analyzing convergence of these algorithms, we design distributed load-side controllers and prove stability of closed-loop power systems governed by these controllers.

Most of these endpoints are distributed on the load side of power systems, in contrast to traditional control resources such as centralized bulk generators.

This thesis focuses on controlling power systems in real time, using these load side resources. (1) Distributed load-side frequency control: We establish a mathematical framework to design distributed frequency control algorithms for flexible electric loads.

In the usual diagnosis problems, the emphasis is put on the signal processing in view of extracting useful data from the global quantities, usually the machine current.The former introduces large, rapid, and random fluctuations in power supply, demand, frequency, and voltage, which become a major challenge for real-time operation of power systems.The latter creates a tremendous number of controllable intelligent endpoints such as smart buildings and appliances, electric vehicles, energy storage devices, and power electronic devices that can sense, compute, communicate, and actuate.If more information about the fault is needed, a physical model of the machine is usually constructed and the fault is simulated to extract the local data.This is a forward problem, where the cause is the fault and the consequences are the distortions in the local quantities.We will provide the necessary software for the numerical analysis of the machine but the candidate will be responsible for developing and implementing the optimization procedure.At the end of the thesis, a prototype machine will be built and the candidate can participate in this process too.Anouar Belahcen (anouar dot belahcen at aalto dot fi) and Dr. The theses are part of a large research project funded by the Estonian Ministry of Education and Research.Two trends are emerging from modern electric power systems: the growth of renewable (e.g., solar and wind) generation, and the integration of information technologies and advanced power electronics.Toomas Vaimann (toomas dot vaimann at ttu dot ee ).The theses are part of a large research project funded by the Estonian Ministry of Education and Research.
