Abstract :
This paper presents analytical expressions to examine the effect of power injection from rooftop PV units on the static voltage stability of distribution system with theoretical and practical limits. Using an equivalent two-bus system, change in the loadability of the system as a direct measure of static voltage stability by PV power is obtained analytically for various limits. The analytical results then are simulated and compared. To validate the methodology, IEEE 37 bus distribution test system is implemented in PSCAD software and simulation results are presented.
