Sažetak
This paper deals with a technique to reduce computational burden in continuation power flow, so that the method can be efficiently used in a control center environment for "real time" applications. To overcome the problem of large CPU time, required by the continuation power flows, the reduction method based on network partition (reducing the system size) and detection of voltage-weak areas, and tangent vector technique (calculated during the predictor step) have been proposed in the literature. The proposed technique is based on a secant predictor together with the fast-decoupled corrector inclusion in the continuation power flow algorithm. Two versions of fast-decoupled Newton-Raphson method, based on the assumption that node voltage magnitudes of neighbouring nodes are close (not equal to 1 p.u.), are included in the proposed continuation power flow and described in the paper. Tests have been performed on several systems. The examples included in this paper are based on simulation using a real-life power system, i.e. a part of Bosnian Electric Power Utility System.
