Abstract:
This paper presents multi-period linearized optimal power flow (MPLOPF) with the consideration of transmission network losses and Thyristor Controlled Series Compensators (TCSC) The transmission losses are represented using piecewise linear approximation based
on line flows In addition, the nonlinearity due to the impedance variation of transmission line with TCSC is linearized deploying the big-M based complementary constraints The proposed model in this paper is evaluated using PJM 5-bus test system The impact of a variety of factors, for instance, the number of linear blocks, the location of TCSC and the ramp rate constraints on the power output and locational marginal price (LMP) is also analyzed using this proposed model
