A new approach to enhance transient stability of power system and its impact on local marginal prices
The formulation of transient stability-constrained optimal power flow and finding its practical solution have recently attracted much attention. In this paper, an approach to improve the transient stability, with increasing critical clearing time (CCT) of the system is presented. This improvement has effects on electricity market prices and local marginal prices (LMP) due to changing the power flow of the line and output powers of the generators. In order to assess the transient stability of the test system, DIgSILENT software is used and to calculate LMPs, MATLAB software is used. The New England 39-bus test system is studied to demonstrate the effectiveness of the proposed scheme for transient stability enhancement and its effects on LMPs.
