Grid code impact on generating stations: A generator owner and Operator's perspective

The evolution of new grid code requirements should impact the choices of new equipment, the performance of current equipment and the design of the generating station. However, the current state of plant planning and licensing may not include a consideration of the Grid Codes and sometimes, the proposed codes are based on a simplified approach used to model generation plants in the transmission system models. This paper focuses on how NERC Standards (grid codes in other countries) may affect generating plant equipment or configuration and what tools would be useful from plant OEM and designers from a utilities point of view. It also describes the concerns and experience the Generation Owner and Operator have regarding implementing the grid codes for generating stations and how some are being addressed, the constraints around model verification activities, and suggested plant analyses and tools needed to help comply with grid codes and protect equipment are discussed.
