| Contents | The course program includes the fundamentals of electrical networks (e.g. architectures, voltage / frequency levels, voltage-frequency regulation) and power quality, with particular attention to the current scenario related to the objectives of the Clean Energy Transition (widespread of power generation plants from renewable sources, especially decentralized, with integration of energy storage systems as a factor of additional flexibility of the electricity system). The level of technical details is modulated in a consistent way with respect to the educational targets of the Degree Course. For the same purpose, the course includes aspects of management interest, specifically with regard to the tariff structure for users and the electricity market. Below is the development by macro themes of the program as scheduled for the course: 1) Electrical systems for energy. Description (voltage and frequency levels) including: generation; interconnection; transmission; distribution. 2) Voltage-frequency regulation in electrical networks. Attention will also be paid to the case of decentralized production, with a focus on the problems of grid stability increasing the share of renewable production and energy storage. 3) Static conversion systems 4) Power Quality in electrical systems, including in the discussion issues related to voltage sags, flickers, amplitude variation, short / prolonged interruptions, harmonic content. 5) Use of electricity: tariff structure (cost of generation, cost of transport, distribution, ....). 6) Electricity market |
