What is the main purpose of the Heavy Load Voltage Schedule Warning?

The main purpose of the Heavy Load Voltage Schedule Warning is to prepare for maximum support of voltages. In power systems, especially during heavy load conditions, voltage levels can fluctuate due to the increased demand on the transmission network. The Heavy Load Voltage Schedule helps operators manage these conditions by providing guidelines and alerts to maintain voltage stability and reliability across the grid. This proactive approach ensures that system operators can take necessary actions to support voltage levels, thus preventing potential blackouts or cascading failures caused by undervoltage situations.

In this context, the emphasis is placed on the importance of voltage support during periods of high consumption, ensuring that the system remains stable and continues to supply power effectively.
