EMT Modeling for Renewable Generation

The number of renewable generation sites is growing, and as a result so is the need for Electromagnetic Transient (EMT) modeling. EMT modeling provides a more detailed response of renewable behaviors than can be achieved through positive sequence modeling. It is used to study systems in more depth and is increasingly required by ISOs.

EMT Model Validation: Develop a site EMT model, utilizing PSCAD, and validate it against a positive sequence model, as is required by CAISO, ISO NE, ERCOT and others.	Detailed Short Circuit Analysis: Perform short circuit analysis considering unbalanced faults, harmonics, transients and develop Voltage Controlled Current Source (VCCS) models for Inverter Based Resources (IBRs).
Interconnection Studies: Perform studies for weak interconnections or areas of high renewable penetration.	Detailed Insulation Coordination and Transient Overvoltage (TOV) Studies: Perform insulation coordination studies and determine overvoltage levels due to switching events.
