The energy carrier "electricity" and its production in global, European and national contexts. Macrosectors of electricity use and typical load diagrams of the electric transmission and distribution system. Overview of the electricity market in Italy. Renewable energy sources: an overview; global, European and national contexts. Technical aspects of the technological transition to distributed generation, energy communities and smart-grids.
Energy efficiency of electrical user systems (IEC 64-8/8-1 standard): location of switchgear (electrical center of gravity method), choice of size of distribution substation transformers, losses in conductors, design criteria for zones/utilities/mesh, high-efficiency electric motors and variable speed drives for fluid handling, electrical load management, power factor correction, power quality and continuity of service.
Energy storage devices for the management of non-programmable renewable sources: electrochemical accumulators, combined electrochemical accumulator and supercapacitor systems, superconducting magnetic energy storage (SMES) systems, hydrogen production and storage (P2G) systems. Fuel cell power generation systems. DC-DC power electronic converters for regulation and control of DC power at terminals of electric generators (photovoltaic modules, fuel cells) or storage systems.
Characteristics of solar radiation and operation of a photovoltaic cell. PV modules and typical PV array configurations for stand-alone or grid-connected generation. Maximum power point tracking algorithms. CEI 0-21 standard and aspects of regulation and control in grid-connected systems.
Wind generation systems: potential producibility and hints on the operating principle of an aeromotor. Power curve of an aeromotor and typical operating range in relation to wind speed. Architectures of fixed-speed or variable-speed wind systems with synchronous or asynchronous electric machine with cage or wound rotor. Control algorithms for maximum power point tracking in variable speed wind systems and algorithms for active and reactive power regulation of grid-connected systems. Offshore wind farms and HVDC systems for grid connection.
Hints on hydroelectric generation systems with run-of-river or reservoir systems. Distributed generation with mini- or micro-hydro systems for island or grid-parallel operation. Energy storage with pumped storage systems. Hints on hydroelectric generation from waves and tides.
