Tidal Modeling Analysis For Potensial Tidal Power Generating In The District West Siberut

Abstract

Numerical modeling is a combination of mathematical representation of the problem in physical form and numerical approximation of mathematical equations. Oceanographic numerical modeling is a system for studying ocean dynamic phenomena into discrete/numerical equations. Tidal power plants are renewable tidal energy. The working principle is the same as a hydroelectric power plant, where water is used to rotate a turbine and produce electrical energy. This research uses descriptive quantitative methods, data processing with MIKE 21 software which results in predicted data on tides and current speeds, ,Results from flow and pass modelingg low tide for potential electricity generation where the highest tide in 2024 in May was 1.53m and the lowest tide in April was -0.92m. In 2025, the highest tide in March will be 2.07m and the lowest tide in April will be -0.56m. for electrical energy potential in 2024 the average is 5.7kWh, and in 2025 the average is 9.07kWh.
