Assessment of dynamic available transfer capability for deregulated power industry
This paper describes the assessment of dynamic Available Transfer Capability (ATC) by considering transient rotor angle stability. Since the loads and wheeling transactions vary dynamically in the deregulated power market, the power producers must respond quickly to those changes without affecting the system security and stability. This paper presents an application of the Evolutionary Programming (EP) algorithm to determine the optimal generation dispatch of power producers with dynamic security constraints. The proposed algorithm is demonstrated to determine dynamic ATC for practical IEEE-30 and Indian utility-62 bus systems with changing load conditions.
