New High Voltage Interconnections with Islands in the Mediterranean Sea: Malta and Sicily. Analysis of the Effects on Renewable Energy Sources Integr…

2018

The present paper shows the benefits coming from the operation of the recent electrical high voltage (HV) interconnections between Sicily, Malta and mainland Italy. These new interconnections allow zonal prices of electricity considerably lower than in the past, ensuring greater flexibility to the system and a better integration of Renewable Energy Sources (RES). After briefly illustrating the two high-voltage electrical systems (Sicily and Malta), and having provided a description of the interconnection cable with Malta and its protection devices, the authors hypothesized two modes of operation (Sicily-Malta system islanded or interconnected to the rest of Europe). For the first case (isla…

Local Green Power Supply Plants Based on Alcohol Regenerative Gas Turbines: Economic and Environmental Aspects

2020

Growing economies need green and renewable energy. Their financial development can reduce energy consumption (through energy-efficient technologies) and replace fossil fuels with renewable ones. Gas turbine engines are widely used in transport and industry. To improve their economic attractiveness and to reduce harmful emissions, including greenhouse gases, alternative fuels and waste heat recovery technologies can be used. A promising direction is the use of alcohol and thermo-chemical recuperation. The purpose of this study is to estimate the economic efficiency and carbon dioxide emissions of an alcohol-fueled regenerative gas turbine engine with thermo-chemical recuperation. The carbon …

European Union commitment towards RES market penetration: From the first legislative acts to the publication of the recent guidelines on State aid 20…

2015

Abstract During the last three decades, the European Union (EU) commitment towards the Renewable Energy Sources (RES) market penetration has been very complex, involving several aspects pertaining to the economic and political action of Member States. This paper seeks to overview the historical development of the legislative EU framework, including a description of the main financial programmes established and managed by the EU Directorates General. Moreover, the work will proceed with the picture of some Investment Funds, ad hoc created for RES undertakings, and managed by the European Investment Bank (EIB) in collaboration with the EU or other foreign Bank Institutes. The delicate matter …

The Influence of Oil Price on Renewable Energy Stock Prices: An Analysis for Entrepreneurs

2020

Abstract This study investigates the relationship between oil price fluctuations and renewable energy stock returns using daily data on Brent crude oil prices and global renewable energy stock market indices between 29 November 2010 and 18 February 2020. The investigation is based on the existing evidence on positive correlations between stock prices and oil prices, but it also considers the shift from non-renewable to renewable sources of energy. A two-stage GARCH(1,1) model and a Granger causality test were applied. Our results show that volatility clustering is present in the renewable energy companies‘ stock prices, but, oil price volatility does not seem to induce any significant effec…

Replacement of Vehicle Fleet with EVs Using PV Energy

2016

The diffusion of Electric Vehicles (EVs), the reduction of environmental pollution and the production of energy from renewable sources (RES), in particular photovoltaic system, wind farm, hydroelectric plants, bioenergy and geothermal plants are the principal aspects discussed in the world. For this reason, the goal of this work is to study for 2014 year in all Italy's Regions; the energy production obtained to photovoltaic systems (PV) and the possibility to use with different percentage this energy for recharge the electric vehicles. In particular, they have been considered different scenarios in function to the km travelled per year from the population. This paper examines the integratio…

PV Reconfiguration Systems: a Technical and Economic Study

2017

Dynamical electrical array reconfiguration strategies for grid-connected PV systems have been proposed as solution to improve energy production due to the mismatch effect of PV plants during partial shading conditions. Strategies are based on the use of dynamic connections between PV panels given by the employment of switches that allow for each panel the series, parallel or exclusion connections, physically changing the electrical connections between the related PV modules, consequentially modifying the layout of the plant. Usually the cost of the dynamic matrix is not taken into account. This novel work evaluates the economic advantages obtained by the use of reconfiguration strategies in…

New approach for harmonic mitigation in single-phase five-level CHBMI with fundamental frequency switching

2017

The main objective of this paper is to study and analyse the voltage output waveform of a multilevel inverter, to suggest a new approach for harmonic mitigation improving the converter performance. These last type of converters represent a new technology in the field of DC/AC electrical energy conversion, presenting advantages respect to the traditional converters. In fact, the multilevel power converters present a low harmonic content and a high voltage level. The paper considers a five-level single-phase cascaded H-bridge inverter and fundamental frequency modulation techniques. The voltage waveform analysis has allowed to identify a working area of the converter where there are lowest va…
