“…Available information on these constraints is of high importance in operating systems close to their stability limits and preventing vulnerable states. The attempt to provide practical models for the OPF under voltage and transient stability constraints has been the impetus toward the development of many methods for calculating TTC [8][9][10][11]. In Reference [12], estimation of point of maximum potential and potential energy boundary surface has been proposed, instead of computing it iteratively, to determine dynamic ATC considering classical model of generators.…”

SUMMARYIn an open transmission access environment, the system operating conditions tend to be pushed close to the stability limits. Small signal stability, commonly in the form of low frequency oscillations, is considered to be a crucial factor since it limits the amount of power transfer through interconnected transmission lines under severe disturbances. This paper presents a novel approach to the assessment of the total transfer capability (TTC) using small signal stability-based security constrained optimal power flow (SSS-SCOPF), thereby enhancing small signal sense under a set of credible contingencies while maximizing power transfer. The eigenvalue perturbation method is used to derive the small signal stability constraint included in SSS-SCOPF, which is a linear inequality expressed in terms of the control parameters. In order to reduce the computational burden, Bender's decomposition method is applied to partition the TTC problem with the small signal stability constraint into an iterative two-stage mathematical programming problem. It is then solved by the primal-dual interior point method (PDIPM) in a master-sub problem iteration manner until no constraint violation occurs for each contingency. The effectiveness of the proposed method is clearly validated by comparison with the conventional optimal power flow (OPF) and SCOPF under the same array of transactions, base case, and line outages for the New England 39-bus system.

“…It also causes convergence problems due to a huge number of variable and equations for large scale electric power systems. Optimal power flow with transient stability constraints was proposed by (Tuglie, Dicorato, Scala, & Scarpellini, 2000;Chen, Tada, & Okamoto, 2001) where the differential equations are used to define the domain. The security constrained OPF method (Hur, Park, K, & Kim, 2003;Shaaban M. , Li, Yan, Ni, & Wu, 2003;Gao, Zhou, M, & Li, 2006), has also been used to solve the Steady-State Security Constrained (SSSC) ATC problem.…”

“…Thus, it is also important to ensure that the system can safely make the transition from the pre to post disturbance operation point. A model, using equilibrium equations as steady state constraints and a dot product concept given by Enrico De Tuglie et al [6] as a rotor angle stability constraint, has been proposed by Xuemin Zhang et al [12] to determine DATC. The sub optimal value of DATC has been computed by T. Jain et al [13] using a structure preserving energy function model for different bilateral and multilateral transactions.…”

-In this paper, a novel dynamic available transfer capability (DATC) has been computed for real time applications using three different intelligent techniques viz. i) back propagation algorithm (BPA), ii) radial basis function (RBF), and iii) adaptive neuro fuzzy inference system (ANFIS) for the first time. The conventional method of DATC is tedious and time consuming. DATC is concerned with calculating the maximum increase in point to point transfer such that the transient response remains stable and viable. The ATC information is to be continuously updated in real time and made available to market participants through an internet based Open Access Same time Information System (OASIS). The independent system operator (ISO) evaluates the transaction in real time on the basis of DATC information. The dynamic contingency screening method [1] has been utilized and critical contingencies are selected for the computation of DATC using the energy function based potential energy boundary surface (PEBS) method. The PEBS based DATC has been utilized to generate patterns for the intelligent techniques. The three different intelligent methods are tested on New England 68-bus 16 machine and 39-bus 10 machine systems and results are compared with the conventional PEBS method.
