When emergency controls cannot keep the stability of the whole system, it is a critical and efficient way to split the whole system into several small isolated islands. Moreover, the generators in the same island are synchronous. In this work, a mixed integer linear programming (MILP) model is set up to analyze the splitting strategies for power system islanding operations with the objective of minimizing...
This paper evaluates the effectiveness of reactive reserves provided by distributed energy resources to increase the loadability of a weak area of the Hellenic Interconnected System. The effect of static capacitor switching is compared to reactive support provided by electronic converters at the same substations. The investigation has been focused on a specific potentially unstable contingency of...
in this paper, a configuration with a dual-port power converter bridging two sides of the transformer is proposed for power quality enhancement in distribution systems. The proposed configuration employs a nine-switch power converter instead of the traditional back-to-back power converter with 12 switches. The high voltage side port works as a double resonance injection hybrid active power filter...
Continuation power flow is an important tool for assessing power system voltage stability. A continuation power flow method for distribution networks is proposed in view of unbalanced three-phase lines and loads in distribution networks with distributed generations (DG). The proposed method consists of tangent predictor and Newton corrector. A local geometric parameterization technique is utilized...
A study has been conducted regarding effect of local Power System Stabilizers and wide area damping controller(WADC) on various inter-area modes present in an inter-connected power system. The local PSS as well as WADC have strategically placed on the paths of dominant inter-area modes, to have maximum beneficial impact on system modal damping.
