The increasing integration of renewable energy sources like wind and solar power into the electricity grid presents unique challenges for generator protection. Traditional protection schemes, designed for conventional synchronous generators (fossil-fuel, hydro), need adaptation to accommodate the distinct characteristics of renewable energy sources. This article explores the challenges of integrating renewable energy sources from a generator protection perspective, discussing the unique characteristics of these generators and their potential impact on protection strategies.

Unique Characteristics of Renewable Generators
Renewable energy sources such as wind and solar power differ significantly from conventional thermal and hydroelectric generators in their operational dynamics and electrical characteristics.
Variable Output and Intermittency
The power output from renewable sources like wind and solar is inherently variable and intermittent, depending on weather conditions. This variability poses challenges in maintaining a stable and balanced grid.
Low Inertia Contribution
Renewable energy systems, especially those...
