Energy storage elements play a crucial role in optimizing the performance and reliability of HRES used for water pumping. By integrating various storage technologies, these systems can effectively manage the intermittent nature of RESs such as solar and wind.
A hybrid energy storage system (HESS) combines various ESSs technologies to improve overall system performance. This approach leverages the strengths of each technology while mitigating their weaknesses, resulting in a more efficient and reliable energy storage solution.
Pumped Hydro Storage (PHS) is a well-established technology for energy storage in hybrid systems. Ref reviewed the integration of PHS with solar and wind power generation systems. They highlighted the flexibility, response time, and performance improvements achieved by using reversible pump-turbine machines in PHS.
In their research, they found that the double storage system is superior over solar-wind-battery and solar-wind-PSH systems. However, the proposed energy management strategy simply gave priority to the use of PSH while battery was used only as a backup. In other words, the charging/discharging process of storage systems has not been optimized.
Recent decades have seen the integration of sophisticated technologies like AI-driven energy optimization and hybrid storage solutions, ensuring greater reliability and sustainability. The initial concept of combining HRESs for isolated water pumping emerged in the late 20th century, primarily focusing on PV solar and wind energy (WE).
In the double storage system type, the wind generation is a preferable source of energy, whereas in the PSH based system, it is the solar generation. There is also a significant drop in the CO 2 emissions resulting from the two studied systems in comparison with the national grid which emissions amount to 0.5 kg of CO 2 per 1 kWh.
