The reliable operation of the interconnected electric system heavily depends upon the accuracy of the dynamic simulation studies. The simulation studies contain models of complex components such as generators, exciter, governors, loads, etc. Many of these models are at best approximate. Hence, the simulation studies must be validated against actual system disturbance from time to time to have confidence...
This paper describes the impact on the power system of a large-scale penetration of photovoltaic (PV) generation. The dynamic response of a PV generation system to rapid change in irradiance is analyzed. Different types of voltage control techniques used to mitigate the negative effects of rapid changes in irradiance are investigated using simulation. The dynamic response of PV generation when subjected...
In this paper, we review some emerging approaches to the challenging problem of cascading blackout risk. International data suggests an increased (but still rare) frequency of large blackouts that makes the risk of large blackouts substantial. We argue that the problem of avoiding blackouts should be posed as jointly mitigating the risk of blackouts of all sizes. There is evidence of a change in cascading...
