Learning outcomes
At the end of the course students are provided with the basic criteria for the planning, operation, control, and protection of medium / low voltage power distribution networks with high penetration of dispersed generation - mainly from renewable sources – and storage units, based on the use of ICT (smart grid) technologies. The course focuses on stability, on voltage and frequency control, on demand side management of the mentioned distribution networks. The course also contains a laboratory module at the end of which students have the basic knowledge for the design and use of a DMS (distribution management system) for active distribution networks
Course contents
The course addresses some of the main issues relevant to the power distribution network operation in presence of distributed generation and of the power apparatuses and systems that allow for its smart management.
In particular, the course deals with the steady state and transient response of power grids by using suitable models of the main components of the electrical power systems, to be implemented in simulation environments such as EMTP-RV.
During the carrying out of the Laboratory activities, some of the methods supporting the smart management of active distribution networks, such as load flow calculation and state estimation, are applied to case studies that take into consideration the recent technical standards for the connection of distributed generation resources to the power grid. Matlab and EMTP-RV are the professional software environments used for the purpose.
The course provides also an introduction to FPGA and Real-Time Labview programming for the development of signal acquisition systems, processing and control on reconfigurable platforms.
