Feasibility Study: Effect of Tidal Turbines Cut-in Speed for Power Generation in New Zealand

This paper proposes and evaluates an optimized system of tidal turbines as a renewable energy generating unit in New Zealand. A comprehensive simulation model has been set up, using several available commercial software packages to test the performance, capacity and efficiency of the proposed system...
