| Growing penetration of wind power challenges to power system security, since the conventional generators may
not have sufficient capacity to compensate wind power fluctuation plus the reverse peak regulation. In this paper,
the high-capacity pumped-storage and fast-response battery-storage are coordinated to compensate the variation
of both wind power and load, aiming at shifting peak load, responding to wind power ramping, reducing the
curtailment of wind and stabilizing the output of thermal units. A practical framework is designed for optimizing
the operation of the hybrid system consisting of the wind, pumped-storage, and battery storage, which can take
full advantages of pumped-storage and battery-storage. The detailed mathematical formulations of the pumpedstorage
and battery-storage are built. Three cases are studied to demonstrate the advantages of the proposed
coordination method. |
