In order to reduce the adverse impact of wind power fluctuation and anti-peak shaving on power grid operation
a coordinated optimal dispatching strategy of “wind-grid-EV charging and swapping station” considering wind power consumption is proposed. Firstly
thermal power is used as an adjustable power supply to assist wind power grid
and through the carbon trading mechanism
the thermal power system is encouraged to actively reduce output and reduce carbon during periods of low grid load and high wind abandonment rate
so as to effectively improve the wind power grid space. Then
on the basis of meeting the power demand of the power grid
the load of the charging and changing power station is connected to further restrain the fluctuation of wind power
and at the same time
the wind power consumption is increased. The objective function is to minimize the peak valley difference of power grid load and optimize the comprehensive operation cost of the system. The low-carbon economic operation model of the joint system is constructed. Finally
the NSGA-Ⅱ algorithm is used to solve and analyze different scenarios. The results show that
this strategy can effectively reduce the system operation cost and the peak valley difference of grid load
and improve the wind power consumption rate of the grid.
