Benefit Analysis of Grid-Connected Floating Photovoltaic System on the Hydropower Reservoir

Abstract

In the step-by-step roadmap for limiting and eliminating power sources that use fossil fuel, especially coal-fired power, as well as for setting the Vietnamese government targets for developing renewable energy for replacement, solar farms and rooftop solar power, followed by floating photovoltaic (PV) power, are considered the best candidates for meeting the goals of land space, PV system operation efficiency, and meeting environmental goals. In addition to the rapid development of PV cell technology are the government’s incentives and financial support for PV plants on the water surface area, which is still very large. Floating PV plants will strongly attract investors in the near future. This study could help stakeholders in the market understand the economic–technical aspects from analyzing economic–financial indicators of floating PV plants with a capacity of 47.5 MW connected to the national utility grid 110 kV at Da Mi hydropower reservoir in Binh Thuan province, Vietnam, in May 2019. This is the first floating PV plant on the reservoir in Vietnam, and is the property of a third party.

An Applied Framework for Smarter Buildings Exploiting a Self-Adapted Advantage Weighted Actor-Critic

“…In recent years, there has been a surge of diverse and extensive research endeavors exploring green energy, renewable power, and their integration into smart home applications. In the pursuit of sustainable land space utilization, solar farms, rooftop solar installations, and floating photovoltaic (PV) power systems are identified as optimal solutions [13]. Notably, an example is found in the investigation of a 47.5 MW floating PV plant connected to the national utility grid (110 kV) at the Da Mi hydroelectric reservoir in Binh Thuan, Vietnam.…”

Utilization Analysis of Solar Cells as an Energy Source to Supply Oxygen at the Military Hospital of dr. Asmir Salatiga

“…By relying on this renewable energy source, hospitals can reduce their dependence on the national grid, which can be a vulnerability in an emergency situation or energy crisis. [9]. Solar panels installed on roofs or open grounds around hospitals provide the opportunity to have a self-sufficient and reliable supply of electricity for critical hospital functions, such as lighting and medical equipment.…”

Technical Analysis of the Large Capacity Grid-Connected Floating Photovoltaic System on the Hydropower Reservoir

“…The advantages of water-based PV (FPV) plants vs. land-based PV (Ground PV-GPV) plants, such as reduced land usage (very important), avoided competing with agricultural or green zones, and limited impact on landscape [6,17,[21][22][23][24]. FPV plants reduced many impacts during allocation, such as deforestation (site accessing), bird mortality, erosion, runoff, and microclimate change are expected to have lower influences on the implementation of conventional PV facilities [21,22,[25][26][27].…”

FPV plants reduced many impacts during allocation, such as deforestation (site accessing), bird mortality, erosion, runoff, and microclimate change are expected to have lower influences on the implementation of conventional PV facilities [21,22,[25][26][27]. Another benefit pointed out in [6,21,23,25,26,[28][29][30][31][32] is that FPV will generate more electricity than conventional PV due to the cooling effect provided by the vapor that interacts with the back of the PV modules in the reservoir.…”

“…On the other hand, humidity, together with temperature, play a main role in determining the module's degradation [21,33]. In addition, it has many other potential advantages [21]: radiation balance (less shading, less soiling), grid access (exploit the existing infrastructure) [6,23], the great potential combination of FPV with hydroelectric power (combine hydropower plants (HPP) with FPV as hydro-PV hybrid systems) [6,18,[22][23][24]34,35], water quality (expect algae growth) [6,22,23,28], reduction of evaporation loss (water saving) [6,7,18,23,28,36], rich application scenarios (integrate aquaculture and fish farming potential) [7], and huge market potential (water body area suitable for FPV deployment is large). It is also easier and cheaper for cooling veil implementation and cleaning mechanisms (the proximity to water; however, this may be hindered in salt water) [23].…”
