Abstract
A source-grid-load-storage networked collaborative frequency control method is disclosed, which comprises acquiring total active power ΔP to be regulated during a secondary frequency regulation process of a power grid; performing frequency regulation by source-grid-load-storage of the power distribution system, allocating power regulation capacities, and determining whether the desired total active power is met after the frequency regulation; if the desired total active power is met, determining whether power of power generation units is out of limit; if the power of the power generation units is not out of limit, keeping active power of the power distribution system in balance to complete frequency regulation of the power grid; if the power of the power generation units is out of limit, correcting the power regulation capacities of the power generation units of the source-grid-load-storage and compensating a power difference to keep the active power of the power distribution system in balance.
