?Introduction of Power system stability
?Classification of stability
?Micro Grid
?Interconnection of micro grid
?Conclusion
Defination-
?Power system stability is an ability of an electric power system for
a given initial operating condition ,To regain a state of operating
equilibrium after being subjected to a physical disturbance with
all system variables  are bounded  so  that practically the entire
system  remain intact.
?Stability is a condition of equilibrium between opposing forces
instability results when a disturbance leads to a sustained
imbalance between the opposing  forces.

?Ability to regain normal and stable operation  after
losing synchronism.
?Load is assume to be applied at a rate which is slow.
?System is Analysis by the set of linear equation.
?Action of Voltage regulators and turbine governers are
not included.
