“…Optimized set-ups could create enough of a difference to explain the difference in costs observed within the results. In addition, certain studies, as well as the results of this research have shown that specific areas and higher altitudes have better conditions for wind power (Hoicka and Rowlands 2011; Intergovernmental Panel on Climate Change 2014; Nur Afandi et al 2020). As such, choosing optimal locations for the production of wind power could also potentially reduce the cost associated with hybrid designs incorporating wind power.…”

“…However, it is possible that a smaller quantity of large capacity wind turbines could reduce the prices associated with hybrid plants containing wind power. This is due to the fact that wind speed typically increases with higher altitudes (Nur Afandi et al 2020). The wind turbines used within this research featured hub heights of 10 m. Many larger wind turbines have hub heights of +50 m (HOMER Energy 2021a).…”

“…to take advantage of higher wind speeds at greater altitudes (Nur Afandi et al 2020) and generate greater quantities of wind power. In addition, the research results (Chapter 5: Results) as well as other studies have shown that the addition of a second renewable energy source has a large effect on reducing excess electricity compared to the addition of batteries alone (Bajpai and Dash 2012;Bentouba and Bourouis 2016;Budischak et al 2013;Hoicka and Rowlands 2011;Khare et al 2016;Krishna and Kumar 2015;Paska et al 2009;Shezan et al 2016).…”

Anthropogenic climate change is driven by the emissions of greenhouse gases (GHG). To limit global warming to 1.5°C above pre-industrial levels and satisfy growing global energy demand, new sources of energy with low GHG emission levels must be developed. Furthermore, at a national level, Canada is not close to meeting its GHG emission reduction targets under the 2015 Paris Agreement. Hybrid solar power plants have been identified as a potential source of reliable, abundant, and environmentally friendly energy. By combining energy sources, hybrid power plants are able to overcome issues such as intermittency and excess electricity that are typically associated with renewable energy sources. However, significant logistical and contextual questions remain concerning the best strategies for hybrid energy development at the national and international levels. This research used hybrid modelling software (HOMER Pro) to perform a direct comparative analysis of the performance and efficacy of a series of different hybrid solar power plant designs. The study compared a variety of hybrid solar power plant designs (using solar, wind, batteries, and fossil fuel generators) on the basis of three equal factors (GHG emission reductions, power generation and reliability, and cost-effectiveness), under the same environmental conditions and location (Peterborough, Ontario). The modelling results showed that the hybrid solar power plant designs H5 (PV-BAT-DG) and H10 (PV-BAT-NG) performed best across all three primary factors of analysis. H7 (PV-Wind-BAT-DG) and H11 (PV-Wind-BAT-NG) produced the lowest quantities of GHG emissions among all of the hybrid solar power plant designs. Canada and countries with similar pollution pricing measures should invest in H7 (PV-Wind-BAT-DG) and H11 (PV-Wind-BAT-NG) hybrid designs in order to maximize GHG emission reductions and develop, diversify energy resources, and service increasing long-term energy demands. Countries that are more concerned with short-term cost-effectiveness as well as reducing GHG emissions should focus on the H5 (PV-BAT-DG) and H10 (PV-BAT-NG) hybrid designs.

“…However, P has some particularities. It is symmetric and positive semidefinite, so the method to be used is the Cholesky decomposition, where the calculations of terms of matrix L are given by Equation (17). This is a less computationally expensive method than the previous ones [32]:…”

“…In addition, it can happen that the accuracy of the measurement devices is not as good as expected, and this can result in an alteration of the values of the collected data [13,14]. Additionally, in general, the wind speeds are measured at a given height that does not necessarily coincide with those of the wind turbine hubs [15][16][17]. These problems must be solved with the aim of accuracy since it is a critical factor when planning power generation [18,19].…”

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.
