“…HPPs respond rapidly to load fluctuations, are easily dispatched, and can operate as a spinning reserve (Mason et al, 2010). These characteristics indicate that HPPs should be used as a convenient solution to compensate for the variability and intermittence of the energy produced from NCRSs (Dester, 2016), which allows greater flexibility in the integration of the latter to electric energy systems (Evans, 2009).…”

The main purpose of this study is to determine the technological options for electricity production based on available electric energy sources in Brazil. The results from this study can be used as a reference for the elaboration of guidelines and public policies that are needed to support plans for electric energy supply expansion. Furthermore, these results can provide input on the construction of energy mix that can meet Brazilian demands and help achieve sustainability in the generation expansion process. The study is based on a multi-criteria analysis methodology that ranks the best alternatives for electric energy production based on criteria linked to sustainability and environmental, technical and economic dimensions.Reference to this paper should be made as follows: Dester, M. and Francato, A.L.

“…In this period, then, biomass power plants use sugarcane bagasse to generate electricity. Furthermore, the storage capacity of large hydropower plant reservoirs can be used to support the penetration of intermittent sources into the grid [32]. The smallest SD is 0.2923, when α = 0.17 and β = 0.25, and consequently, p h = 17%, p w = 21% and p pv = 62%.…”

Abstract:Integrating renewable and intermittent energy sources into the electricity sector challenges traditional energy systems based on predictability and constant supply. Studies oncomplementarity between climate-related resources from different regions and countries are proving to be an efficient means to overcome the variability of single-source use. Although Rio de Janeiro State (Brazil) has set goals of increasing its use of clean and low carbon energy, there is no study to support the expansion process. Given that, this work aims to assess the complementarity potential of small hydropower plants, wind farms, and photovoltaic panels in the state. Power output estimates have been based on wind speeds, solar radiation and river flow data and without generation technologies assumptions. The Pearson correlation coefficient and linear programming have been used to comprehend and optimize the renewable mix. Daily complementarity has been observed among the energy sources considered, especially between hydro and solar resources. The optimization process showed an improvement of 61% in the total power standard deviation, from the worst-100% hydro power-to the best case-62% of photovoltaic, 21% of wind, and 17% of hydro power. The results highlight the benefits of appropriately joining the three sources and suggest investing in photovoltaic generation.
