Reactive power flow equation
http://nepsi.com/resources/calculators/calculation-of-reactive-power-in-a-1-phase-system.htm WebThe expression and calculation of transmission loss (TL) play key roles for solving the power system economic dispatch (ED) problem. ED including TL must compute the total TL and incremental transmission loss (ITL) by executing power flow equations. However, solving the power flow equations is time-consuming and may result in divergence by the iteration …
