This paper seeks to solve the long-term transmission expansion planning problem in power systems more effectively by reducing solution search space and computational effort. The proposed methodology finds adds cutting planes based on structural insights about bus angle differences along paths. Two lemmas a theorem are which formally establish validity of these onto underlying mathematical formu...

This paper presents a cost-based TSO-DSO coordination model to quantify the value of local flexibility services and analyze its impact on transmission grid expansion system operation. Flexibility is provided DC power flow by microgrids within integrated AC distribution model. The model’s objective minimize overall cost investments procured achieved using bilevel optimization approach where exch...
