Grid frequency can be kept stable through a combination of measures such as balancing electricity supply and demand, using frequency control and regulation systems, and integrating renewable energy sources with smart grid technology. Balancing supply and demand involves adjusting power generation to match the amount of electricity being consumed at any given time. Frequency control and regulation systems help to maintain the grid frequency within a narrow range by automatically adjusting power output from generators. Integrating renewable energy sources with smart grid technology allows for better management of variable energy sources, helping to stabilize the grid frequency. Overall, a combination of these measures helps to ensure a stable grid frequency and reliable electricity supply. **
