HIGH-SPEED METHOD FOR LARGE SCALE POWER SYSTEMS

摘要

Disclosed is a high speed method for fault level constrained-optimal power flow (FLC-OPF), capable of improving the speed of calculation when power network reformation algorithm (NRA) based on FLC-OPF is applied to a large scale system. To achieve the purpose, the method to apply the NRA based on FLC-OPF to the large scale system includes a step (a) of determining matrix components of bus impedance and Thevenin impedance by using Kron reduction in a state in which a consecutive variable (X) having a predetermined connective impact is removed when the large scale system is seen from a fault level constrained-bus; and a step (b) of calculating a Jacobian component and a Hessian component by using the matrix components of the bus impedance and the Thevenin impedance. Therefore, the speed of calculation in the large scale system is improved.
