Abstract: Precision load control is an important security and stability control system to improve the overall frequency stability of the new power system. It can realize the function of millisecond precision load control to ensure the safe and stable operation of bulk power grid and the consumption of clean energy. On the basis of current management regulations, the paper, through conducting a questionnaire survey on the power users who have access to the precision load control system in Shanghai, puts forward a specific plan for orderly and rapid power supply restoration in case of an accident and provides the logical diagram of restoring power supply for precision load control system, which offers reference and basis for development of precision load control system and improvement of precision control method in the future.
Key words: new power system; precision load control; frequency stability; demand side response; strategy research
