“…On the other hand, the human population is growing exponentially, causing an increase in energy demand. However, the most utilized energy source is still dominated by non-renewable fossil fuels (80%) [2]. Hence, developing alternative energy sources is necessary to improve energy security and reduce adverse problems because of conventional fuels.…”

“…By denoting the number of locations that are taken into account as m and by considering the number of sums, subtractions, products, divisions, and roots necessary to determine each of the aforementioned decompositions, the Gaussian method needs 2m 3 3 operations, the QR dependent on Householder decomposition needs 4m 3 3 , and the Cholesky one uses m 3 3 [32]. Furthermore, the fact of applying this decomposition to the correlation matrix also offers the possibility of quickly and easily getting a solution of the correlated random series closer to the real ones, as long as the distribution is a standardized Normal, with which it can be ensured that the solution also has a standardized Normal distribution.…”

“…The negative impact of fossil fuel gas emissions on human health and also on the planet health raises the awareness about the harmful effects of such emissions [3], and due to this, different countries have agreed to limit global warming to a value lower than 2 • C concerning preindustrial era [4]. To ensure the compliance of greenhouse gas emissions reduction into the atmosphere, the European Union has published a guide showing different scenarios [5].…”

Simulation of Wind Speeds with Spatio-Temporal Correlation

Nowadays, there is a growing trend to incorporate renewables in electrical power systems and, in particular, wind energy, which has become an important primary source in the electricity mix of many countries, where wind farms have been proliferating in recent years. This circumstance makes it particularly interesting to understand wind behavior because generated power depends on it. In this paper, a method is proposed to synthetically generate sequences of wind speed values satisfying two important constraints. The first consists of fitting the given statistical distributions, as the generally accepted fact is assumed that the measured wind speed in a location follows a certain distribution. The second consists of imposing spatial and temporal correlations among the simulated wind speed sequences. The method was successfully checked under different scenarios, depending on variables, such as the number of locations, the duration of the data collection period or the size of the simulated series, and the results were of high accuracy.

“…Most renewable energy resources, for example solar [16], wind [17], hydro [18], geothermal [19], tidal [20], and biomass [21], could be directly or indirectly converted into electrical energy, relayed either to on-grid units or isolated or off-grid loads [22,23]. Such renewable energy sources have low or no environmental impacts [24,25]. Technologies based on solar energy are thermal (heating/cooling), photovoltaic (PV), or thermoelectric.…”

Advances in building-integrated photovoltaic (BIPV) systems for residential and commercial purposes are set to minimize overall energy requirements and associated greenhouse gas emissions. The BIPV design considerations entail energy infrastructure, pertinent renewable energy sources, and energy efficiency provisions. In this work, the performance of roof/façade-based BIPV systems and the affecting parameters on cooling/heating loads of buildings are reviewed. Moreover, this work provides an overview of different categories of BIPV, presenting the recent developments and sufficient references, and supporting more successful implementations of BIPV for various globe zones. A number of available technologies decide the best selections, and make easy configuration of the BIPV, avoiding any difficulties, and allowing flexibility of design in order to adapt to local environmental conditions, and are adequate to important considerations, such as building codes, building structures and loads, architectural components, replacement and maintenance, energy resources, and all associated expenditure. The passive and active effects of both air-based and water-based BIPV systems have great effects on the cooling and heating loads and thermal comfort and, hence, on the electricity consumption.
