Based On Trust Region Interior Point Method Static Atc

The calculation of ATC(Available Transfer Capability) has become an important part of the research of the electric power market. This paper mostly researches the calculation of ATC,and uses a trust region interior-point method to the calculation model of TTC(Total Transmission Capacity) based on the OPF(Optimal Power Flow) arithmetic. The numerical results of IEEE-39 bus system are used to compare the method with the SQP method and demonstrate the effectiveness of the method.
