Abstract
Frequency stability in power systems has a direct relation with power grid inertia. In other words, the inertia of the power grid depends on the inertia of its generators. The inertia in the power grid changes when its generators are tripped or disrupted from the main grid. Because the remaining generators are not able to supply all of the active power consumed by consumers, under frequency load shedding should be applied. However, in much electrical power grid, there is no control or communication link and there is a little room for doubt that calculation of real-time inertial would be complicated at this situation. In this chapter, a decentralized under frequency load shedding method based on load voltage deviation and rate of change of frequency is proposed to overcome this problem. The proposed scheme benefits from voltage deviation to limit the amount of loads that are engaged in the process. Results of procedure testing are demonstrated through the dynamic simulation by using digsilent power factor. Using local data available by some new appliances, such as numeric relays, gives the proposed method a distinct advantage over other methods. One of the good points about the new method is that it can be applied by operators as a practical method to recover frequency and voltage to normal mode in a contingency situation.
