Uncertain Load Models and Their Representation in Power Systems | Original Article
Various uncertainties exist in the power systems and one of them is load uncertainty. As the power system network is undergoing various market pressures these days, it becomes very important to tackle the uncertainties. Due to the penetration of the distributed generation at the load ends in the system, the load bus uncertainty becomes a matter of serious concern. In this paper, the handling and representation of various uncertain load models are given. The affect of uncertainties in the system has been observed by a dynamic load flow program and severe case has been identified by a sensitivity index namely absolute minimum eigen value of load flow Jacobian. The proposed scheme is implemented on IEEE-14 bus system.
