In this paper, Based on the nature of the interaction power controller, the unified expression of node equivalent and additional inject current and power is derived in condition of the node admittance matrix of original network is symmetry, which is used to fixing parameters of the interaction power controller in process of iteration. In order to achieve the minimum network loss, optimal loss of power...
Based on additional nodal power injection method, this paper presents nodal power injection model of UPFC for three phase power flow calculation. Based on this model, use decoupling-compensation theory to calculate three phases power flow. Finally, the rationality and effectiveness of three phase load flow with UPFC is verified by the simulation. And the results reflect the effect of UPFC for improving...
Area partitioning that splits a power network into self-sufficient islands is an emergency control to stop the propagation of disturbances and avoid cascading failures. This paper provides a survey of the state-of-the-art of power system islanding techniques and proposes the application of a multilevel graph area partitioning algorithm that are applicable to very large power grids. As an emergency...
Cascading failures present severe threats to power grid security, and thus vulnerability assessment of power grids is of significant importance. Focusing on analytic methods, this paper reviews the state of the art of vulnerability assessment methods in the context of cascading failures. These methods are based on steady-state power grid modeling or high-level probabilistic modeling. The impact of...
This is a summary of the presentation in the panel session on blackouts for the 2008 IEEE PES General Meeting. This presentation will discuss the state of the art methodologies for the prevention of cascaded events in blackouts. A new topic concerning the identification of basic patterns of cascaded events following a contingency will be included.
