A positive T ini shows the time periods that the generating unit has been online at the beginning of scheduling horizon.A negative one shows the time periods that the generating unit has been o?ine at the beginning of scheduling horizon.
1.2Load Data
In Figure2,the load pro?le is illustrated.Table4provides the total system demand per hour and Table5presents the node location of the loads,as well as load at each node as a percentage of the total system demand.The load data is based on[2].

2Implementation Including Wind Power Production
It is recommended to include six wind farms at di?erent locations throughout the grid.It is proposed to locate the wind farms at3,5,7,16,21and23nodes.In this case,the capacity on the transmission lines connecting the node pairs(15,21),(14,16)and(13,23)is reduced to400MW,250MW and 250MW,respectively.This is done in order to introduce bottlenecks in the transmission system.
