Abstract
The implementation of Demand Side Management (DSM) in order to enhance power system operational flexibility has gained more and more attention during the past decade. However, DSM could endanger the system stability because it changes the characteristics of system demands. This paper establishes the overall impacts of DSM on angular stability of power system with high penetration of Renewable Energy Sources (RES) and high system operational uncertainty. The overall effects of DSM are assessed by considering the distance (in terms of Euclidean Norm) between stability manifolds of the system before and after applying DSM. The results show that changes of Euclidean Norm with pre-defined positive direction can be adopted to indicate the overall effect of DSM on system angular stability. They further indicate that depending on the system inertia, RES penetration levels and DSM application levels, the effects of DSM on power system angular stability could be very different. A modified version of the 68-bus NETS-NYPS test system in DigSilent/PowerFactory environment has been adopted to perform dynamic simulations.
