A measurement setup for electric bicycles powered from renewable energy sources
2014
In this paper a measurement system for a pedalassist rickshaw is described. It has been designed and realized with the purpose of a deep analysis of operating time, range and general performance of the prototype vehicle. The three-wheel velocipede under test, developed in the SDES laboratory of the University of Palermo, is equipped with two battery packs, and a photovoltaic panel which is used to recharge one of the packs at a time. To further improve the autonomy of this mean, a fuel cell will be added as a power source, whose consequent improvement in performance could be easily investigated by the presented measurement setup. An Arduino board has been employed to receive and store all c…
Techno-economic evaluation of PV based institutional smart micro-grid under energy pricing dynamics
2020
Abstract The solar photovoltaic (PV) system with battery energy storage have a lot of potential to provide reliable and cost-effective electricity and to contribute in micro-grid operation. However, the operational performance of such type of micro-grid system depends on many factors (e.g. techno-economic sizing, energy management among the sources, market energy prices dynamics, energy dispatch strategies, etc.). In this paper, a typical Indian institutional energy system has considered for techno-economic performance evaluation for operating as a smart micro-grid under market energy pricing dynamics. The institutional energy system has integrated PV, battery storage and DG for operating a…
Adaptive energy management strategy for sustainable voltage control of PV-hydro-battery integrated DC microgrid
2021
Abstract DC microgrid has relatively more advantages of power quality, not requirement of reactive power, higher operational efficiency compare to AC microgrid. DC microgrid can facilitate effective integration of distributed clean energy resources and efficient solution for providing electricity to remote areas (e.g. North Eastern States of India). Recently, India has commissioned small hydro, solar PV and battery storage integrated DC microgrids (MGs) to meet the locally increasing load demand of northeastern states. The sudden change in solar insolation during the load power dynamics can cause unbalanced power flow in such isolated MGs. Due to the slow response time of small hydro power …
An integrated energy simulation and life cycle assessment to measure the operational and embodied energy of a Mediterranean net zero energy building
2022
Abstract Net Zero Energy Buildings can play a key role in reducing the energy use, greenhouse gas emissions and the use of natural resources associated to the built environment. It is widely recognized that in low energy building a shift in relevance may occur from the operational to the embodied impacts. However, building performance assessment focus mostly on the operational phase and on primary energy consumption. This study aims to assess the energy and environmental impacts of a residential net zero energy building expanding the analysis to the full life cycle and to a wide range of environmental impact categories. The methodological approach integrates a non-steady state building ener…
Battery capacity estimation for building-integrated photovoltaic system: Design study of a Southern Norway ZEB house
2017
Building-integrated Photovoltaic system (BIPV) with energy storage (ES) can help in reducing the peak demand as well as overcoming the intermittency of the load and PV production. In Southern Norway, a Smart Village Skarpnes is developed for zero energy buildings (ZEBs). In this Smart Village, five houses are built with BIPV system. Its important to estimate the appropriate battery sizing with consideration of local PV production and load profile taking into account the battery characteristics with minimization of the annual electricity bill. In this study, real operational results of house (C6) from the Skarpnes Smart Village is used for estimating the capacity of battery energy storage fo…
Battery Capacity Estimation for Building Integrated Photovoltaic System: Design Study for Different Geographical Location(s)
2017
Abstract Building Integrated Photovoltaic system (BIPV) with energy storage (ES) can help in reducing the peak demand, improving the power quality and control dispatching of the power. Adding a proper size of battery ES to the grid-connected PV system could reduce the overall investment cost as well as reducing the grid-dependency. A typical battery energy storage capacity is going to be determined by considering the real-time operational (PV production as well as load consumption) data. In this study, real-time operational data of a residential load (C6 house) with BIPV system located Southern Norway as well as institutional load (Teri university) with BIPV located in New Delhi, India are …

The proposed system consists of a single photovoltaic transducer to harvest energy and simultaneously detect ambient light. T…
Performance Assessment of Building Integrated Photovoltaic and Battery Energy System: A Case Study of TERI-Retreat Facilty in India
2019
Building integrated photovoltaic (BIPV) with energy storage can play an important role not only in demand side management but also in a micro-grid system in coordination with other distributed generators. The operational analysis of BIPV system and energy storage with contribution to local load profile is needed for its grid connected operation, as well as for integrating it in the micro-grid system. In this work, a typical institution has been selected, where the PV system and energy storage are operated for supplying local load in coordination with the grid. The institutional load profile has been analyzed with essential and non-essential loads for understanding the operation and contribu…

The decarbonizing process of the transportation system and the spread of unplanned renewables energy source, such as photovoltaic and wind energies, brought the constant need of ever more efficient energy storage technologies. Among these technologies, batteries, particularly the li-ion chemistry, are widely used in automotive and energy storage applications. For an optimized management of the cell it is advisable to have models that can accurately describe cell behaviour. In this paper a battery model for performance simulation in automotive application is identified.

Challenges in Energy Systems for the Smart-Cities of the Future
2012
In the last years the European Union has actively promoted the renewable energies and the Combined Heat and Power (CHP) also for residential and tertiary buildings. The exploitation of renewable sources and cogeneration seems hampered by the regulatory wall that prohibit for residential, tertiary and commercial buildings the constitution of users clusters. In fact, the unification up to a threshold value of some tens of kVA, at least, can facilitate the installation of renewable energy power plants as solar PV modules or CHP systems (cogeneration) or CCHP systems (tri-generation), overcoming technical and economical barriers and combining several load profiles. The actual distribution syste…
