A Study of Transient Stability Constrained Optimal Power Flow with Multi-Contingency

Abstract

Transient stability constrained optimal power flow (SCOFF) has been recognized as a potentially mighty tool for secure and optimal operation planning of power systems since its advent, especially in nowadays open transmission access environment. However, although a lot of works have been done regarding this attractive topic, no SCOPF with multi-contingency has been reported until now. In this paper, first, the necessity for multi-contingency SCOPF (MC-SCOPF) is illustrated based on the results of the IEEJ WEST10 model system. Then MC-SCOPF problem is formulated and a solution method is proposed. Computation results on the IEEJ WEST10 model system demonstrate the effectiveness of the presented MC-SCOPF formulation and the efficiency of the proposed calculation approach.
