Interval Algorithm for Power Flow Calculation with Uncertain Load
Chi Zhang · 2004
Power flow calculation is a fundamental tool for all kinds of studies in power s ystems. However, in practical system, some original data may be uncertain such a s the load. Hence, calculating power flow with uncertain loads i s important and practical. This paper presents a method to solve the power flow problem with uncertain loads using interval arithmetic. Based on interval mathem atics, an expression of the power flow model with interval variables, is propose d and the power flow calculation with Krawczyk-Moore interval iterative method. Finally, interval power flow result on Ward Hale 6-bus system is shown.
