“…These same linear shift factors may also be used to compute sensitivities of branch flows to branch outages, known as line outage distribution factors or LODFs [12]. Given a PTDF matrix H w , the corresponding n l × n l LODF matrix L can be constructed as follows, where l ij is the element in row i and column j, representing the change in flow in branch i (as a fraction of its initial flow) for an outage of branch j.…”

Abstract-MATPOWER is an open-source Matlab-based power system simulation package that provides a high-level set of power flow, optimal power flow (OPF), and other tools targeted toward researchers, educators, and students. The OPF architecture is designed to be extensible, making it easy to add user-defined variables, costs, and constraints to the standard OPF problem. This paper presents the details of the network modeling and problem formulations used by MATPOWER, including its extensible OPF architecture. This structure is used internally to implement several extensions to the standard OPF problem, including piece-wise linear cost functions, dispatchable loads, generator capability curves, and branch angle difference limits. Simulation results are presented for a number of test cases comparing the performance of several available OPF solvers and demonstrating MATPOWER's ability to solve large-scale AC and DC OPF problems.

“…Constraint (9) represents the injection shift factor (ISF) of each line with respect to each node for each contingency. A Thorough description and details of the computation of LODF and ISF can be consulted in [27] and [28], respectively. It is worth mentioning that power flow limits are taken into account but not enforced within the proposed approach.…”

This paper presents a model and a solution approach for the transmission network expansion planning (TNEP) problem that integrates security constraints given by weighted transmission loading relief (WTLR) indexes. Such indexes integrate shift and power distribution factors and allow to measure the severity of overloads in normal conditions and under any single contingency. Furthermore, the inclusion of small-scale generation was considered as complementary to TNEP solutions. The proposed model was solved by means of the metaheuristic NSGA-II (Non-dominated Sorting Genetic Algorithm II), which enabled to find a set of solutions that represent a trade-off between the cost of the expansion plan and its security level. Several tests were performed on the 6-bus Garver system and the IEEE 24-bus reliability test system, thus showing the applicability of the proposed approach. It was found that the inclusion of small-scale generation in strategic nodes allows to reduce the cost of expansion plans and increases their level of security for single contingencies.

“…In almost all of these methods, power system equipment outage analysis is used to perform the contingency analysis [12]- [18]. In some cases, voltage stability is evaluated using contingency analysis of transmission lines and then each contingency is ranked according to its influence on the voltage level of the bus-bars [14], [18]- [21]. In [15], the influence of the line outage contingency on the loading level of network transmission lines has been studied.…”

A new approach to reduce the expected energy not supplied in a power plant located in a nonexpandable transmission system A new approach to reduce the expected energy not supplied in a power plant located in a non-expandable transmission system AbstractThe main objective of most of power plants is to inject power as much as possible into the grid from the power plants. However, the transmission system may restrain the output capability of the power plant, especially, if the power plant is located in an area of non-expandable transmission system. In this situation, any disturbance in the nearby transmission system may force the plant to generate lower than its rated value, which disables it from selling the remaining available generated power to the costumers and also increases the cost of energy not supplied. In this paper, an efficient method is proposed to determine the maximum output capacity of the power plant, by which the avoidable cost of energy not supplied, is not burdened on the plant. The effectiveness of the proposed method has been evaluated on a three machine test system and also on the actual large Mashhad power plant in Iran.
