With a total of 4 patents to his name, his work is pivotal in enhancing the efficiency and reliability of power distribution systems.

Latest Patents

One of Yanman Li's latest patents is a source-grid-load-storage networked collaborative frequency control method. This method involves acquiring total active power to be regulated during a secondary frequency regulation process of a power grid. It performs frequency regulation by utilizing the source-grid-load-storage of the power distribution system, allocating power regulation capacities, and ensuring that the desired total active power is achieved. If the power generation units are within limits, the active power of the power distribution system is balanced to complete the frequency regulation. If not, the method corrects the power regulation capacities to maintain balance.

Another significant patent is an emergency control method and system based on source-load-storage regulation and cutback. This method regulates the output power of generating sources according to a power regulating quantity and frequency regulation requirements. It ensures that the output power compensation and frequency of each generating source remain within permissible ranges, maintaining a balance between power supply and demand. Standby energy-storage power stations are utilized to fill power gaps, allowing for effective management of large load disturbances.
