Introduction: Small hydroelectric power plants have emerged as a promising solution for harnessing the energy potential of flowing water in rivers and streams. While these plants are relatively compact, enhancing their efficiency is imperative for achieving maximum power output. One innovative approach to improve efficiency is the incorporation of sequential transmission hydro turbines, which offer distinct advantages over traditional systems.
The global pursuit of sustainable energy solutions has intensified in recent years, with a growing emphasis on harnessing the untapped potential of small hydroelectric power plants. These compact facilities leverage the kinetic energy of flowing water to generate clean and renewable electricity, offering a viable alternative to conventional energy sources. While small hydroelectric power plants hold significant promise, the optimization of their efficiency remains a critical aspect for ensuring their economic viability and contribution to the renewable energy transition.

Small hydroelectric power plants have emerged as a crucial component of the renewable energy landscape, contributing significantly to the global effort to transition towards sustainable and environmentally friendly energy sources. In the pursuit of optimizing the efficiency of these plants, researchers and engineers have explored various technological advancements, and among these, the integration of sequential transmission hydro turbines has garnered attention for its potential to address inherent challenges faced by traditional systems.
Traditional hydro turbines, such as Kaplan and Francis turbines, have been widely employed in small hydroelectric power plants. However, their efficiency is often compromised under conditions of variable water flow and fluctuating loads.
