“…Any efficient contingency filtering technique can be used to this purpose. In this work, unless otherwise specified, we use the non-dominated contingency (NDC) approach motivated by the good results obtained with it in the context of PSCOPF [18]. Additional filtering results will also be provided by means of the classical severityindex based contingency ranking technique [1], [3].…”

Abstract-This paper deals with techniques to solve the corrective security-constrained optimal power flow (CSCOPF) problem. To this end, we propose a new iterative approach that comprises four modules: a CSCOPF which considers only a subset of potentially binding contingencies among the postulated contingencies, a (steady-state) security analysis (SSSA), a contingency filtering (CF) technique, and an OPF variant to check post-contingency state feasibility when taking into account post-contingency corrective actions. We compare performances of our approach and its possible variants with classical CSCOPF approaches such as the direct approach and Benders decomposition (BD), on three systems of 60, 118, and 1203 buses.

“…The basic idea is that only a few contingencies are binding and require preventive and/or corrective re-dispatch; post-fault constraints related to non-binding contingencies are redundant and can be ignored (e.g. [25], [26]). However, all existing methods consider operation problems in isolation, not dealing with investment decisions that impose a more limiting coupling structure.…”

Abstract--Significant uncertainty surrounds the future development of electricity systems, primarily in terms of size, location and type of new renewable generation to be connected. In this paper we assess the potential for flexible network technologies, such as phase-shifting transformers, and nonnetwork solutions, such as energy storage and demand-side management, to constitute valuable interim measures within a long-term planning strategy. The benefit of such flexible assets lies not only in the transmission services provided but also in the way they can facilitate and de-risk subsequent decisions by deferring commitment to capital-intensive projects until more information on generation development becomes available. A novel stochastic formulation for transmission expansion planning is presented that includes consideration of investment in these flexible solutions. The proposed framework is demonstrated with a case study on the IEEE-RTS where flexible technologies are shown to constitute valuable investment options when facing uncertainties in future renewable generation development.

“…Viewed in this light, it can be parented to the significant body of work related to contingency filtering and contingency screening in power systems (see, e.g., [15], [16], [17]). Most of the approaches for contingency filtering however rely on deterministic algorithms while the one proposed in this paper is a stochastic one.…”

Abstract-This paper presents an approach for assessing, in operation planning studies, the security of a large-scale power system by decomposing it into elementary subproblems, each one corresponding to a structural weak-point of the system. We suppose that the structural weak-points are known a priori by the system operators, and are each one described by a set of constraints that are localized in some relatively small area of the system. The security analysis with respect to a given weakpoint thus reduces to the identification of the combinations of power system configurations and disturbances that could lead to the violation of some of its constraints. We propose an iterative rare-event simulation approach for identifying such combinations among the very large set of possible ones. The procedure is illustrated on a simplified version of this problem applied to the Belgian transmission system.
