Time series load flow calculation #283
-
|
Hello, i was using GridCal 5.1.8 to perform load flow calculation. I have input generator and load data using GUI interface. On the result i can understand if generator that connected to slack bus is have different value with my setting. my question is why other generator that i set Zero on the input generator time series have result Active and Reactive power that more than the limit? thank you for you help |

Hi! I believe the discrepancy is due to fact that the reactive power in generation devices is calculated if the device is_controlled property is true. This is, gerators make buses PV and in PV buses, Q is calculated regardless of what Q or pf you specify...if is_controlled = true, else the bus is PQ and the reactiva power estimate remains. Then, where does Q come from at the inputs analysis? An initial Q estimate is generated with the generator power factor (pf) but that estimate is corrected by the power flow algorithm if is_controlled = true. I hope this helps |

Thank you for the explanation,It is solved by changing is_controlled = False. |
