Sir,When we run continuation power flow for particular system, we get p-v curve for selected bus. using this p-v curve, we can find Voltage stability Margin (in MW) on that bus by difference of operating point to nose point lamda. I agree lambda at nose point provides maximum loading value but that is for that bus only for which p-v curve is plotted. My question is How to find Voltage Stability Margin for whole Network using P-V curve ? I mean how to find maximum lamda for whole network using p-v curve? Thanks.

I donⴠquite understand your question, can you please elaborate. The maximum value of loading scaling parameter ᬡmbda⠧ives a measure of how much power can be transferred for a given transfer direction. So, lambda is also a measure of the nose point for the whole network.

My question is - How to get nose point for whole network (all buses) using PV curve ? I want to find network voltage stability margin rather than individual bus margin using CPF. Thanks.
