Energy Management of a Hybrid Photovoltaic-Wind System with Battery Storage: A Case Report

2019

This work presents a case report related to the management and the monitoring of a hybrid photovoltaic-wind system with battery energy storage, installed at the administrative offices building of the municipality of Valderice (Italy) within the framework of the Italy-Tunisia ENPI cooperation project Le Développement Durable Dans la Production Energétique Dans le Territoire (DE.DU.ENER.T.). The paper describes the hybrid system and briefly reports the monitoring data for a whole year, comparing the real production with the expected one and evaluating some performance indexes of the system. The performance indexes are very simple and have been defined only with the purpose of sh…

DEMAND Project: A Peak Load Shaving Strategy for End-User Consumers

2018

Battery energy storage systems (BESS) are becoming increasingly widespread in modern power systems, thanks to the important benefits they can provide to the electricity grid. Indeed, BESS can be used in time shifting applications, storing energy during off-peak periods and discharging during peak times (when the cost of electricity is high). When BESS are used for peak shaving purposes, they also contribute to relieve peak demand charges, thus ensuring a saving for the consumers. This paper describes a peak load shaving strategy defined within the DEMAND project. The strategy is able to guarantee the flattest daily power diagram and the maximum benefit for the electricity consumers, reducin…

Reuse of electric vehicle batteries in buildings: An integrated load match analysis and life cycle assessment approach

2019

Abstract The increasing use of renewable energy technologies for electricity generation in buildings will require a growing number of battery energy storage systems (BESS) to enhance the reliability of electricity supply. The increasing number of retired electric vehicle (EV) batteries, expected from the automotive sector, can match this demand as EV batteries can be used as BESS, considering that they have about 80% of their original energy capacity. In this context, the study aims at examining the system, consisting of a BESS made by retired Li-ion EV batteries, a photovoltaic plant (20 kW) and the electricity grid, that provides the electricity required by an existing nearly net zero res…

Second life employment of a traction battery for load match optimisation of a residential building: Life cycle and operation applications

The increasing use of renewable energy technologies for the electricity generation in buildings will require a growing number of energy storage systems (ESSs) in the next years in order to reduce the mismatch between the highly variable on-site electricity generation and the building load. Retired electric vehicle batteries (EVBs), before recycling, can be used for this purpose, considering that they have about 80% of the original energy capacity. In this context, the study aims at examining an ESS made by retired EVBs, in order to identify its optimal size for reducing the mismatch in a net zero energy building equipped with a photovoltaic plant and to assess the life cycle energy and envi…

Reuse of electric vehicle batteries in a residential stationary application: an integrated load match analysis and life cycle assessment approach

A simulation study for assessing the impact of energy storage systems for Fast Reserve with additional synthetic inertia control on the Continental E…

2022

This article shows the results of a simulation study on the application of battery storage systems for providing fast frequency regulation (the so-named Fast Reserve) with additional synthetic inertia control. The aim of the study is to assess the impact of the extension of the regulation provided by the FRUs to all the Continental Europe synchronous grid, with the same power proportions of the first Italian FRU auction. The simulations are conducted in two different scenarios: a base one related to 2020 and a future one related to 2040 and based on ENTSO-E projections for load and generation. The results show that, for the reference incident of 3000 MW, the frequency quality parameters in …
