Research on the Method of Stabilizing the Power Output Fluctuation of Wind Farm by Electric Vehicles
Owing to the inherent randomness and intermittency of wind power
the output power of wind farm tends to fluctuate greatly. However
considering the high cost of energy storage device
it is not good for the wind farm to configure energy storage device. This paper studies the fluctuation of output power fluctuation in the wind power field considering the participation of electric vehicles. Firstly
according to the requirement of the national standard of stroke
"active power change"
the rate of output power of wind farm is described by the concept of climbing rate. Then
using the robust optimization method to deal with the uncertainty of wind power
wind turbines and electric cars
coordinated control of bi-level optimization model:the upper model decision makers is a wind farm
with wind farms sell electricity utility maximization as the objective function; The lower-level model decision makers are electric car owners
and the cost of electric power costs is minimized to the target function. In addition
this robust optimization model is transformed into a hybrid integer linear programming problem by using the linear programming dual theorem and Karush-Kuhn Tucker (KKT) optimality conditions. Finally
the effectiveness of the proposed model and method is verified by simulation.
