Detailed description of the topics:

1. Technical visit to two configurations of PV system at Politecnico di Torino for highlighting the main components: PV modules, inverters and protections with their dimensions and installation structures for the connection to the grid (1 h).

2. Theory: the I-V curve of a PV module from the technical specifications of manufacturers; the dependence of I-V curves on irradiance and cell temperature. Qualification tests to simulate accelerated ageing (2 h).

Practice: calculation of the electrical parameters of the PV modules in conditions different from the rated STC by datasheet of the manufacturers (2 h).

3. Theory: configurations and tasks of inverters for grid connection from the technical specifications of the manufacturers (2 h).

Practice: determination of the optimal configuration (number of series connected modules Ns x number of parallel connected strings Np) for the PV array according to the voltage/current/power constraints imposed by the inverter (2 h).

4. Theory: conventional calculation of energy production from the evaluation of solar irradiation on the plane of the PV array, loss sources in the energy production; profiles of load consumption and determination of self-sufficiency and self-consumption (2 h).

Practice: calculation of the productivity from a PV system in terms of reference yield, performance ratio, and energy balance with the energy consumption to determine the self-consumption and self-sufficiency of an active user (2 h).

5. Theory: management of the grid connection as the selection of power transformers and distribution lines with proper protections (2 h).

Practice: calculation of power losses and voltage regulation in the components (transformers and lines) used for grid connection of a large-scale PV system (2 h).

6. Theory: the tasks of the transmission/distribution system operators: the active power/frequency control, the reactive power/voltage control; how to synchronize generator with grid; parallel operation of synchronous generators (2 h).

7. Theory: basic aspects of grid-connected PV plants equipped with electrochemical batteries. (1 h)

Technical visit to a micro-grid in which three PV systems, equipped with storage, feed electricity to an energy community of three users at Politecnico di Torino (2 h). https://pvzen.polito.it
