Modal frequencies and damping coefficients are crucial quantities to characterize and predict the structural behaviour of wind excited structures. Wind turbines in parked conditions can be treated as telecommunication or lighting towers, for which a fair amount of experimental studies is available. However, natural frequencies and damping...

The present paper discusses technical aspects of the vortex-induced vibrations (VIVs) of structures excited by the wind in the framework of the spectral model, which is applied by many codes and guidelines for civil engineering verifications. Quantitative thresholds related to Scruton number domains, where the structural response can be...

In this chapter we present the fundamentals of the Levelized Cost of Energy (LCOEn) focusing on renewable power plants and multi-vector energy systems. After having introduced the basic formulation for the LCOEn, we extend its definition to polygeneration systems, hybrid systems (generators working in parallel with energy storage devices as a...

The deployment of Energy Communities can help to increase the provision of sustainable energy from renewable energy sources at urban, industrial, and commercial levels, granting benefits to all the community members. Their effective integration in the form of microgrids (and nanogrids) will undoubtedly help to decarbonize the energy sector and,...

Energy Communities can help to satisfy our energy needs in a more sustainable and efficient manner. Since 2019, the European Union is strongly promoting their development; amoung the European countries, Spain and Italy are taking a leading role in this paradigm change. However, additional regulatory and technical steps must be carried out to...

In this chapter we present the results of the calculation of the LCOEn for three representative case studies. The first case study is the Smart Polygeneration Microgrid (SPM) at the Savona Campus of the University of Genoa (Italy), a low voltage microgrid which includes both thermal and electrical generators and loads. The second case study is...
