“…Moreover, the authors estimated that the time complementarity between hydro and SPVS increased significantly with the presented methodology [32,33]. Thus, the correlation coefficient decreased from −0.20 to −0.74, clearly indicating that hydro production is increased when SPVS output is minimum, and vice versa.…”

Supplying power to remote areas may be a challenge, even for those communities already connected to the main grid. Power is often transmitted from long distances, under adverse weather conditions, and with aged equipment. As a rule, modernizing grid infrastructure in such areas to make it more resilient faces certain financial limitations. Local distribution may face stability issues and disruptions through the year and-equally important-it cannot absorb significant amounts of locally-produced power. The European policy has underlined the importance of energy production in local level towards meeting energy security and climate targets. However, the current status of these areas makes the utilization of the local potential prohibitive. This study builds on the observation that in the vicinity of such mountainous areas, irrigation dams often cover different non energy-related needs (e.g., irrigation, drinking water). Transforming these dams to small-scale hydropower (SHP) facilities can have a twofold effect: it can enhance the local energy portfolio with a renewable energy source that can be regulated and managed. Moreover, hydropower can provide additional flexibility to the local system and through reservoir operation to allow the connection of additional solar photovoltaic capacities. The developed methodological approach was tested in remote communities of mountainous Greece, where an earth-fill dam provides irrigation water. The results show a significant increase of renewables' penetration and enhanced communities' electricity autarky.

“…The ρ h g product is the specific weight of water, which depends on the water temperature, but varies very little over the temperature range that a watercourse usually presents and is approximately constant [25]. For complementarity studies, the head h can be considered constant, especially because SHP plants have a small or even null water storage capacity [12,13,26]. Consequently, the product ρ h gh can be understood as a constant (K h ) and the Equation (3) can be rewritten as P h = K h Q (4)…”

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.

“…This prevailing situation needs to be addressed appropriately for the cost-effective energy supply in remote areas. [11][12][13] This is not only beneficial for the end users; it is also beneficial for power distribution companies (DISCOs) for their inclusive development. However, the involvement of the huge capacity storage battery with these schemes limits its utility concerning the energy cost and environmental issues with reference to the dumping of huge battery waste.…”

Summary Electrification in remote villages using locally available hybrid renewable energy sources is a viable option to eradicate energy poverty. At the same time, energy supply to the unprivileged population at the affordable cost is a major issue. Moreover, appropriate technology is the key factor for the sustainable operation of small‐scale generation system in remote places. Therefore, in this paper, a simple controller‐based standalone solar photovoltaic (PV) augmented micro‐hydro generation system suitable for remote area has been proposed. Because of its robustness for wide speed range applications, doubly fed induction generator (DFIG) has been used for micro‐hydro power generation in the proposed scheme. The developed controller effectively stabilizes the load voltage with load, micro‐hydro generation, and solar PV generation variations. In order to provide cost‐effective renewable power supply to the rural population, a generation capacity trade‐off criterion has been developed considering solar PV and micro‐hydro generations as the two operators. In the proposed trade‐off process, cost analysis has been performed considering the salvage dumping cost (SDC) for solar PV. The proposed hybrid generation scheme has been simulated through HOMER Pro‐3.2 for cost‐benefit analysis. Also, a prototype hardware set‐up for the proposed scheme has been developed and tested successfully. In this paper, Section 1 describes literature review; Section 2 discusses power generation strategy; Section 3 discusses energy cost analysis; and Section 4 describes experimental results.
