this paper presents an application of benders decomposition to deal with the complexities in the simultaneous generation expansion planning (gep) and transmission expansion planning (tep). unlike the power system operation fields of study, the power system planning methods are not expected to be fast. however, it is always preferable to speed up computations to provide more analysis options for...

In regions with high penetration of Distributed Energy Resources (DER), grid congestion is mostly caused by power feed-in generators. this context, conventional approaches for solving the problems are Active Power Curtailment (APC) DER and reinforcement. wake increased generation, it not only interest how to obtain reinforcement, but also consider APC during planning. The challenge such plannin...
