Abstract
out wind speed of wind turbine g. R wgWake radius generated by the wind turbine w at wind turbine g along the wind direction. RRotor radius of all wind turbines. X wgDistance between wind turbines w and g along wind direction. C. Variablesx/y First-stage/second-stage variables.I g,t Binary variable for the on-off states of wind turbine g, 1/0 indicates the on/off state.z g,t /u g,t Binary variable, 1 if wind turbine g at time interval t starts up/shuts down and 0 otherwise.P ,t,s Active power output of the cluster at time interval t under scenario s. p t,s Probability of the sth scenarios in the JPD at time interval t.P ij,t,s /P D ij,t,s Active power in the head end of branch ij in AC/DC network at time interval t under scenario s.Q ij,t,s Reactive power in the head end of branch ij at time interval t under scenario s.Ũj,t,s / Ũ D i,t,s Square of the voltage of bus j in AC/DC network at time interval t under scenario s.Ĩij,t,s / ĨD ij,t,s Square of the current of branch ij in AC/DC network at time interval t under scenario s.P gj,t,s /Q gj,t,s Active/reactive power outputs of wind turbine g in bus j at time interval t under scenario s.
