Abstract

Demand Side Management (DSM) is being actively considered as potentially effective way to enhance power system operational flexibility. Due to the fact that DSM changes not only total demand but also demand compositions at affected hours, it could subsequently affect system dynamic response and stability performance. This paper investigates the potential impact of DSM on power system angular stability depending on the type of demand and demand composition. The results show that the main indicators of angular stability, namely transient stability and damping of the most critical electromechanical mode, are very dependent on the type of the load model used to model demand, and on actual demand composition. All simulations are carried out in DigSILENT/PowerFactory environment using a modified version of the 68 bus NETS-NYPS test system.
