Modern electricity network are evolving in complexity as renewable energy sources such as solar and wind are integrated into the grid. In contrast to traditional power plants, renewable energy generation changes with the weather, making it more difficult to align electricity generation with customer demand

This study investigates load frequency control, an important process that maintains a stable grid frequency. A stable frequency ensures electrical equipment operates safely and efficiently. As renewable energy grows, traditional frequency control methods are becoming less effective because they were built to operate with conventional power plants.

The paper discusses the latest developments in frequency control include advanced control methods and modern technologies that respond faster to changes in electricity demand and renewable energy production. These new approaches can improve power system reliability, reduce disturbances, and support the transition to cleaner energy systems.

The review also identifies future research areas that can help build smarter and more resilient power networks. As electricity systems continue to evolve, improved load frequency control will play an important role in ensuring reliable and sustainable energy for communities around the world.
