87230 - Smart Grids Fundamentals M

Learning outcomes

At the end of the course students are provided with the main criteria for the design and the management of medium/low voltage distribution networks with high penetration of dispersed generation - mainly from renewable sources - and ICT (smart grids). The main concepts related to the safe and reliable operation of these networks, i.e. protection against faults, state estimation, voltage control, losses minimization and demand side management too are owned by the students at the end of the course, along with the knowedge of plug-in electrical vehicles impact on grid planning and control. The course contains also a laboratory module at the end of which the students own the basis for using, designing and programming a DMS (Distribution Management System) for active distribution grids.

Course contents

The course of Fundamentals of Smart Grid 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 real-time Labview programming for the development of signal acquisition systems, processing and control on reconfigurable platforms.
