- This paper is also based on the concept of VIP. It computes PQ boundary but uses parabolic
approximation of the PQ curve. (http://ieeexplore.ieee.org/document/6281498/)
- This method utilizes all phasor measurements at all buses and network topology to compute
the thevenin equivalent system (network reduction is done here but using PMU data for
updating current and voltage). The maximum power is calculated using linear approximation.
The proposed approach calculates three indices after estimation of Thevenin parameters for
real, reactive and apparent power. (http://ieeexplore.ieee.org/document/4075891/)
