In this article an economic and environmental study is carried out on PV solar energy installations connected to the Spanish electrical grid system. The study has been performed on installations situated in the city of Zaragoza (with an irradiation value approximately equal to the average value...

This paper shows a complete techno-economical analysis on facilities that make use of wind turbines and photovoltaic (PV) generators for the production of hydrogen by means of electrolysis. Besides, the surplus of electrical energy produced can be sold and injected to the electrical grid.

The purpose of this paper is to study the development of photovoltaic (PV) systems in some countries of the European Union (EU). We establish the stage of development of each country, their short- and long-term degree of compliance and the trends of international investors favouring one market...

This paper describes an application of the Strength Pareto Evolutionary Algorithm to the multi-objective optimization of a stand-alone PV–wind–diesel system with batteries storage. The objectives to be minimized are the levelized cost of energy (LCOE) and the equivalent carbon dioxide (CO2)...

In the Mediterranean region, there are many drip irrigation systems with pumps that are powered by diesel generator sets (gensets). Although they could be powered by renewable energy produced on-site, technical and economic factors make that difficult. Moreover, the seasonal nature of demand...

The integration in electric power networks of new renewable energy facilities is the final result of a complex planning process. One of the important objectives of this process is the selection of suitable geographical locations where such facilities can be built. This selection procedure can be...

This paper presents a comparison of two new advanced statistical short-term wind-power forecasting systems developed by two independent research teams. The input variables used in both systems were the same: forecasted meteorological variable values obtained from a numerical weather prediction...

Nowadays, around 1.44 billion people have still no access to electricity, most of them living in rural areas in South and Southeast Asia, and Sub-Saharan Africa. The major residential energy consumption in these regions is for cooking. This energy demand is covered by firewood, agricultural...

This study is to analyze how to extend the sugar plants by a polygeneration technology to produce sugar, bioethanol, biogas and bioelectricity. The possibility of selling the bioelectricity to the national grid in Brazil is also investigated through optimizing the energy production at an...

In this paper, a storage system has been considered to be added to a private electricity facility in order to reduce the electricity bill. This kind of system could make sense with a time-of-use (TOU) tariff (with two or three periods of different electricity price) or a real-time pricing (RTP)...
