Latest Patents

Zhijun Zhang's latest patents include 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 kept balanced to complete the frequency regulation. If not, adjustments are made to correct the power regulation capacities.

Another notable 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 maintains output power compensation and output frequency within permissible ranges, ensuring a balance between power supply and demand. Standby energy-storage power stations are utilized to address power gaps, allowing for effective management of large load disturbances.
