The chief aspect of solving Optimal Reactive Power Dispatch Problem (ORPD) is to minimize the real power loss and also to keep the voltage profile within the limits. In this paper, a new metaheuristic optimizing algorithm that is the simulation of “Grand Salmon Run” (GSR) is developed. The salmon run phenomena is one of the grand annual natural actions occurrence in the North America, where mil...

For Multi-Objective Optimal Reactive Power Dispatch (MORPD), a new approach is proposed as a simultaneous minimization of the active power transmission loss, the bus voltage deviation and the voltage stability index of a power system are obtained. Optimal settings of continuous and discrete control variables (e.g., generator voltages, tap positions of tap changing transformers and the number of...

– Core-based testing, which is described by the proposed IEEE standard P1500, is an effective test method for Systems-on-Chip (SOC) containing embedded cores. This test method is usable for all classes of digital cores and provides solutions that allow automatic identification and configuration of testability features in SOC containing embedded cores. In this moment, IEEE P1500 is restricted to...

In this paper, a novel hybrid optimization algorithm, which combines a firefly algorithms and Artificial Bee Colony algorithm (FFAABC), is proposed for solving the economic power dispatch (EPD) problem. The hybrid algorithm is structured with two stages. The first stage uses the search by firefly algorithm (FFA) and second stage is a search with Artificial Bee Colony algorithm (ABC). The hybrid...

In this paper a new approach for transmission pricing is presented. The main idea is voltage angle allocation, i.e. determining the contribution of each contract on the voltage angle of each bus. DC power flow is used to compute a primary solution for angle decomposition. To consider the impacts of system non-linearity on angle decomposition, the primary solution is corrected in different itera...

Recently, there has been a growing concern about the overload status of the power grid networks, and the increasing possibility of cascading failures. Many researchers have studied these networks to provide design guidelines for more robust power grids. Topological analysis is one of the components of system analysis for its robustness. This paper presents a complex systems analysis of power gr...

IEEE 1394 is a standard for a high performance serial bus interface. It encompasses both isochronous transfer mode, which is suitable for real-time applications, and asynchronous transfer mode, which is appropriate for delay-insensitive applications. This standard can be used as a basis for constructing a small-size local area network. Two queueing models are proposed for a network operating un...

This paper aims at providing a solution to optimum power flow (OPF) in considered power systems by using a flexible genetic algorithm (GA) model.
