Muhammad, You are not taking into account shunt elements (Qshunt) and branch charging injections (Qbsh): Tota System Q = Qgen + Qshunt + Qbsh - Qload - Qloss = 0.0 = 82.4 + 21.2 + 24.4 - 73.5 -54.54 = 0.0 Regards Uriel El 01/04/2014, a las 05:02, MUHAMMAD FARAZ SAHITO <[email protected]<mailto:[email protected]>> escribió: Hi Every One, I am running AC Power flow using Newton Raphson method for IEEE 14 bus system, I am using following command: results = runpf('case14'); When i get the results I see total reactive Power Injection [Q (MVAr) Generation = 82.44] and total consumed reactive Power [Q (MVAr) Load = 73.50]. If we subtract consumed reactive power from injected reactive power we get the Loss. Total Reactive Power Loss = Total Reactive Power Injection - Total Reactive Power Consumption = 82.44 - 73.5 = 8.94 MVAR where as AC load Flow is giving 54.54 MVAR, Can any one explain why this loss is coming wrong.
