Available Transfer Capability Calculation with Post-contingency Generation Rescheduling/load Curtailment
نویسندگان
چکیده
The available transfer capability (ATC) is an important index indicating the remaining transfer capability in the physical transmission network for further commercial activity above existing commitments, In this paper, ATC mathematical model considering post-contingency generation rescheduling and load curtailment is first formulated. Benders decomposition method is then used to partition the ATC model above into a base case master problem and a series of independent subproblems relevant to various contingencies. Finally, an improved parallel solution scheme is employed to improve the convergence. Numerical results on a 4-bus test system show clearly the eflectiveness of the presented method and necessity of considering post-contingency generation rescheduling and load curtailment in caicuinting ATC.
