The Puerto Rico Electric Power Authority has proposed increasing the renewable energy generation of the island to an estimated 1,600MW. This will be accomplished by adding alternative energy sources (e.g. wind, solar, land fill gas, and waste) distributed throughout the island. Environmental benefits and increased energy independence should be weighed against the potential impact that increased generation of renewable energy will have on the electrical grid. Renewable energy sources are a variable source of energy due to their dependency on natural resources, creating a strain on the electric grid. In this study, a stability analysis of the electrical power system of Puerto Rico is conducted by observing the impact of the proposed increase in wind power generation.
