The available transfer capability indicates how much interarea power transfers can be increased without compromising system security. That is, the available transfer capability is the total transfer capability minus the base case transfer together with adjustments to allow some margin of safety. Much of the experience in computing transfer capabilities concerns line #ow limits and uses DC load ...

In this paper, Particle Swarm Optimization (PSO) algorithm and Guaranteed Convergence PSO (GCPSO) are proposed to determine the allocation of Thyristor Controlled Series Compensator (TCSC) and Static Var Compensator (SVC) for maximizing the Total Transfer Capability (TTC) between source and sink area by considering voltage limits and thermal limits in a power system. The optimization is made on...

The computation of Total Transfer Capability (TTC) is a significant task in the deregulated environment. In this paper, Firefly (FF) algorithm is used to solve the Optimal Power Flow (OPF) based TTC problem. Real power output of generators in source area and real power load in drop area can be adjusted to obtain the maximum transfer capability. The value of TTC can be made more accurate by cons...

This paper proposes a method calculating total transfer capability(TTC) and critical voltage using static power model based on real-time recording data, traditional power system dispatching calculation doesn’t consider load model, which does not agree with the real, this paper compares TTC and critical voltage under different load model and P-V curves, on which load model has a strong influence...
