The present paper investigates the role of energy storage systems within microgrids characterized by the presence of power plants fed by renewable sources. In particular, the analysis is focused on microgrids where photovoltaic fields coupled with storage batteries are used to satisfy the energy loads of a well-defined area, such as a urban...

Universities can play an active role in facilitating the deployment at a wide scale of the sustainability concept, strictly cooperating with public-private institutions and civil society. Following this path, the University of Genoa, Italy, decided to transform its Savona Campus into a Living Lab aimed at creating a model of a sustainable urban...

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...

The present paper is focused on the integration of renewable sources and storage systems in the household sector with a special attention to the adoption of home smart charging infrastructures for electric vehicles. The proposed mathematical model can be used to optimally design and daily manage a nanogrid composed of a photovoltaic plant, a...

The goal of the present paper is that of presenting the main research activities carried out at the Savona Campus of Genova University in the electric mobility and microgrid sector, with a particular focus on vehicle-to-grid (V2G) and vehicle-to-building (V2B) projects. The infrastructures of the E-Mobility Microgrid Laboratory are described...

A transition towards electrification of the public transport sector is ongoing in many cities around the world, as a response to global warming and pollution. Therefore, in this paper, the electrification of the public transport system of the city of Savona is proposed. In particular, the study focuses only on the urban lines and it aims to...

In this paper, the role of the monetary incentives in the employee performance is investigated in the context of Public Administration (PA). In particular, the distribution of monetary incentives among the employees based on the position held, is compared with a merit approach which tends to recognize and reward individual contributions....

Short-term electric power forecasting is a tool of great interest for power systems, where the presence of renewable and distributed generation sources is constantly growing. Specifically, this type of forecasting is essential for energy management systems in buildings, industries and microgrids for optimizing the operation of their distributed...

Lightning ElectroMagnetic (EM) fields represent the most cumbersome part of the lightning-induced voltages computation process. Their evaluation is usually performed through a numerical routine or with simplified analytical expressions, which are valid only assuming an infinite ground conductivity and specified channel base current waveform....

In this paper, an optimization model for polygeneration microgrids is presented. In particular, the system is characterized by trigeneration plants, renewables, district heating, thermal and electrical storage systems and flexible loads. The control variables are represented by the schedule of the power plants and of the deferrable demand,...

The article provides analytical expressions for the electromagnetic fields generated by a lightning return stroke characterized by a channel-base current with arbitrary time waveform, in presence of either a perfectly conducting or a lossy ground, assuming the transmission line model for the current along the channel. In this second case, a...
