The invention discloses a
capacity optimization and auxiliary peak regulation method for a regional
wind power plant group
energy storage power station. The method comprises the steps that 1, a BESS (
battery energy storage
station)
composite function charging and discharging realizing method of
wind power plant group
power fluctuation stabilization and power network peak regulation is considered, and a
capacity optimization calculating model is built by using the BESS operation cost minimization as a target; 2, the super-short-term
wind power is utilized for predication, and a real-time optimization
operation model is built by using the maximization of gains when the BESS synchronously participates in the
power fluctuation stabilization and the power network peak regulation as a target; 3, the
cost sharing and
gain distribution mode and method of the BESS
system operation are provided. Through the adoption of the technical scheme, an
energy storage system with the configuration required by a regional wind power
plant can be planned, the economic and reasonable
energy storage capability is optimized and calculated, meanwhile, an prioritization scheme that the energy storage
system participates in the power network peak regulation in an auxiliary way is provided, and the reasonable and efficient operation level of a regional
wind field configuration energy storage system is improved.
