The definition of flexibility provided by PHS has yet to reach a consensus. In general, response time, regulation rate, and stability are identified as key indicators of flexibility definition [18, 19].Javed et al. [20] pointed out that the flexibility of PHS was strongly connected to its performance in frequency modulation, voltage stability, and load adaptation.
