DESC:TECHNICAL FIELD
[0001] The present disclosure relates to the field of a renewable energy technology. More particularly the present disclosure relates to a system and method for generating electrical energy by converting hydrokinetic energy in aquatic environments.

BACKGROUND
[0002] The following description of the related art is intended to provide background information pertaining to the field of the present disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.
[0003] Hydroelectric power, derived from the energy of flowing water, is a significant renewable energy source used globally for electricity generation. Surface Hydrokinetic Power (SHP) plants represent a subset of hydroelectric facilities designed to harness the energy of flowing water within large canal infrastructure to generate electricity. These canals, which form part of extensive infrastructure projects in many countries, primarily serve water resource management purposes such as power distribution, irrigation, and sewage conveyance.
[0004] However, despite their critical role in water management, most canal networks worldwide remain underutilized, primarily serving as conduits for water transport. The passive utilization results in limited revenue generation, predominantly reliant on water royalties and government grants, with the substantial investment in building and maintaining these canal networks taking decades to recover. SHP plants, typically with capacities of several megawatts, offer an environmentally friendly alternative by leveraging natural water resources with minimal greenhouse gas emissions. Integrating SHP plants within canal systems presents an opportunity to repurpose existing water infrastructure for renewable energy production. However, this integration poses engineering challenges, such as managing fluctuations in water discharge and velocity, as well as addressing structural limitations posed by diverse canal types. The development of SHP plants within canal systems requires meticulous planning and innovative engineering solutions to optimize energy generation while ensuring the sustainable management of water resources. The optimization necessitates continuous monitoring and effective operational strategies to overcome challenges such as siltation, water management issues, and structural constraints inherent to canal environments. However, there is a growing imperative to develop integrated systems that generates sustainable electric energy in aquatic environments.
[0005] There is, therefore, a need in the art to provide a system and method that can overcome the shortcomings of the existing prior arts.
