    This project will develop a Procedure for Feasibility and System Impact Studies to evaluate the interconnection of solar and wind generation projects. This structured procedure includes the methodology, reliability and security criteria and the different types of analyses needed (power flow, short circuit and transient stability). Transmission system planning engineers should perform this procedure in order to identify any adverse system impacts on the transmission system, and specify the infrastructure modifications that are needed to safely and reliably complete the interconnection. The first step of this work was the evaluation of Interconnection Feasibility and Impact studies reports for actual solar and wind generation projects from many owners and operators in the United States. The purpose was to evaluate the methodology used by transmission system planning engineers of different utilities, power companies and transmission system owners, to perform interconnection studies. The second step was the identification and evaluation of different reliability criteria from several organizations in the United States, such as the North American Electric Reliability Corporation (NERC). The purpose of this step was to evaluate the reliability criteria used in interconnected system in United States and the reliability criteria of Hawaii, which is an isolated electric power system, such as Puerto Rico. In addition, this step includes the identification of the technical requirement, which guarantees a reliable interconnection of renewal projects in different electric power systems, where renewable energy penetration is increasing rapidly. The third step was the development of the Procedure for Feasibility Studies and the System Impact Studies based on best practices identified from other power systems. This Procedure is divided in two sections: (1) the guides to create a base case to perform powerflow, short circuit and transient stability analyses and (2) the guides to perform the analyses required in the Feasibility and System Impact Studies. Simulations of the different analyses are presented to evaluate the interconnection of 75 MW wind project to the Puerto Rico Electric Transmission System.
