Integrated Transmission Network Planning by Considering Wind Power’s Uncertainty and Disasters

The penetration of wind turbines and other power sources with strong uncertainty into the grid has increased in recent years. It brought significant technical challenges to systems’ operation. volatility intermittency increase risk insufficient transmission capacity lines. Therefore, traditional deterministic planning methods for grids are no longer fully applicable. On hand, frequent disasters years have posed a great threat system, especially grid. This requires design lines high standards, such as skeleton networks, withstand disasters. With aim address these problems, bi-level integrated network model is developed by considering power’s load guarantee under Chance constraints used characterize uncertainty, adopted cope Moreover, based on convex relaxation method, chance converted probabilistic inequalities be solved. proposed method simulated IEEE 118 bus obtained scheme further analyzed scenario tests. And result tests proves validity reasonableness method.
