“…Reserves, specifically spinning reserves, also serve as proxies for explicitly dealing with uncertainty in demand and variable generation (e.g., wind and solar plant) output. However, again following [12], we argue that enforcing N-k reliability (even when k = 1) is likely to ensure sufficient spinning reserves are online to deal with forecast errors in both demand and variable generation. We demonstrate that this is indeed the case in Section 2.3 by analyzing the CCUC for a 6-bus system.…”

“…As noted in [12][p. 1056], "The primary purpose of spinning and non-spinning reserves is to ensure there is enough capacity online to survive a contingency". Hedman et al [12] make this argument in the context of N-1 reliabiliy; the argument for the exclusion of reserve models is even stronger for N-k contingencies. Reserves, specifically spinning reserves, also serve as proxies for explicitly dealing with uncertainty in demand and variable generation (e.g., wind and solar plant) output.…”

“…In particular, various researchers introduced mixed-integer programming and decomposition-based methods for more efficiently enforcing N-1 reliability, e.g., see [10,11,28,17,12,19]. However, due to its computational complexity, security-constrained unit commitment considering the full spectrum of NERC reliability standards has not attracted a comparable level of attention until very recently.…”

“…-We ensure the existence of a feasible post-contingency corrective recourse, taking into consideration generator ramping constraints and the no-contingency (nominal) state economic dispatch; -We consider the loss of both generation units and transmission lines; -We propose novel decomposition methods to solve the contingency-constrained CCUC efficiently, and show that models and methods proposed by [12], [19], [26], [27], and [29] are all special cases of our general approach.…”

We consider the problem of minimizing costs in the generation unit commitment problem, a cornerstone in electric power system operations, while enforcing an N-k-ε reliability criterion. This reliability criterion is a generalization of the wellknown N-k criterion, and dictates that at least (1 − ε j ) fraction of the total system demand must be met following the failures of k or fewer system components. We refer to this problem as the Contingency-Constrained Unit Commitment problem, or CCUC. We present a mixed-integer programming formulation of the CCUC that accounts for both transmission and generation element failures. We propose novel cutting plane algorithms that avoid the need to explicitly consider an exponential number of contingencies. Computational studies are performed on several IEEE test systems and a simplified model of the Western US interconnection network, which demonstrate the effectiveness of our proposed methods relative to current state-of-the-art.

“…These optimal transmission switching models, which formulate the optimization as a mixed integer problem, usually assume n − 1 contingency reliability (Hedman, O'Neill, Fisher, and Oren, 2009) (in general, n is the number of system components), which means that the effects of single line and generator failures on the network are included in the analysis. The latest models of Hedman, Ferris, O'Neill, Fisher, and Oren (2010) even include generator startup and shutdown costs as well.…”

In practical power systems, in order to study the results of optimal power flow (OPF) for a sub‐transmission network (STN), the downstream primary distribution network is usually modeled as constant load. However, in practical distribution grids, the operators are constantly transferring load from one primary distribution feeder to another one because of, eg, congestion problems or maintenance plans. Considering distribution switching actions can improve the performance of sub‐transmission OPF tool that typically aims at reducing the operation cost of STN. This paper presents a new sub‐transmission Alternating Current (AC) OPF (ST‐AC‐OPF) considering load transferring (LT) between primary distribution feeders implemented through distribution maneuvers. The proposed OPF tool is tested on an illustrative practical example as well as on a real‐world Tehran STN. The numerical results show that the proposed model can obtain a more optimal operating point than conventional ST‐AC‐OPF in terms of the operation cost and load shedding.
