摘要: This paper presents an improved approach for online computation of reactive power contributions from various sources to meet the load demand and loss based on network flow using Y-bus method. The equivalent model line is considered by separating shunt part transmission integrating into nearby buses proper accounting support produced charging capacitances, as separate like conventional capacitors in ancillary service market. Detailed case study with base optimised carried a modified IEEE-30 bus system. proposed also compared proportional sharing method highlight associated advantages. Simulations result show that provides fair accurate results comparison other
