The flexible control strategy study of receiving end large power grid under global energy connection

摘要

This paper puts forward a comprehensive control method of UHV receiving end power grid based on user intelligent interaction. The load flexible control cloud platform, together with the existing dispatching operation and marketing system, realizes load regulation by smart plug-in units with the function of micro-control and infrared adjustment. When high power deficiency happens caused by UHV failure or emergency shutdown, the load flexible control cloud platform can play an important role on hierarchical control of virtual power plants flexibly and fine. The large scale virtual power plants response to form clusters aggregation effect, contributing large power to support grid power supply and demand balance, to ensure the safe and stable operation of power grid.
