Abstract :
Operation of power systems is subject to disturbances, such as faults, that increase the operational risk. Under a "day ahead" planning, it is useful to forecast system loadability capacity such an operational margin. This paper introduces a methodology for assessing and characterizing the maximum loadability of a power system when it undergoes contingencies on an hourly basis by means of Monte Carlo simulations and continuation power flow methods. In addition, the methodology allows the identification of weak areas in the system. The proposed methodology has been tested in the New England 39 bus system and the IEEE 118 nodes system.
