Hydro-Solar Hybrid

1.Solution Overview: The hydro-solar hybrid solution is an innovative energy management system that integrates solar energy, hydropower and a battery energy storage system. It utilizes the water resources of reservoirs, the regulatory functionality of energy storage systems, and the clean power generation capacity of floating photovoltaics to attain efficient, stable, and sustainable energy supply.

2.Solution Analysis: Floating Photovoltaics: Photovoltaic panels are installed on the water surface of reservoirs, fully utilizing the extensive water surface area for photovoltaic power generation. Solar energy is converted into electricity, providing clean power to the surrounding regions. The power generation efficiency of the photovoltaic panels is elevated due to the cooling effect of the water surface. Moreover, floating PV panels do not occupy land areas, minimizing land usage and potentially related environmental damage issues. Energy Storage System: The system is equipped with energy storage devices such as batteries or a pumped-storage system. Excess electricity is stored during the peak hours of photovoltaic power generation and discharged at night or during peak electricity consumption periods to balance the supply and demand of the power grid electricity. For floating photovoltaics, the energy storage system can resolve the intermittency issue of its power generation and guarantee the stability of power supply. Additionally, in the event of power grid failures or emergencies, the energy storage system can act as a backup power source to ensure the operation of key facilities. Dike & Reservoir: Beyond traditional functions such as flood control, irrigation, and water supply, dike reservoirs can also collaborate with the energy storage system and floating photovoltaics. For instance, pumped storage power stations can leverage the height difference of the water levels in the reservoir for energy storage and release; the water of the reservoir can be utilized to cool the energy storage devices or photovoltaic panels, enhancing the operational efficiency and service life of the equipment.

3.Solution Value: Enhance Energy Supply Stability: The combination of floating photovoltaics and the energy storage system effectively mitigates the intermittency problem of photovoltaic power generation, providing stable power output to the power grid. Simultaneously, the dike reservoirs’ regulatory functionality further reinforces the reliability of energy supply and reduces dependence on fossil fuels. Optimize Energy Structure: This solution fully harnesses renewable energies such as solar and hydro energy, reducing the consumption of traditional energy sources such as coal and oil, and lowering carbon emissions and environmental damages. It transforms the energy structure towards a clean, low-carbon and sustainable state. Save Land Resources: Floating photovoltaics do not occupy land resources, fully capitalizing on the water surface space of reservoirs and enhancing land utilization efficiency. For regions with scarce land resources, this model demonstrates substantial practical significance. Promote Economic Development: The construction and operation of a Hydro-Solar Hybrid project can stimulate the development of local industries, create employment opportunities, and facilitate regional economic growth. Simultaneously, it reduces electricity costs and improves the energy accessibility for enterprises and residents.
