Distribution networks reconfiguration is among the main tasks in distribution management system. The networks reconfiguration is determined by opening and closing switches devices. This reconfiguration can be static or dynamic. In static reconfiguration, the loads are assumed to be constant, while in dynamic reconfiguration loads are assumed to vary according to time. In this work, a dynamic reconfiguration...
The Topology Processing is a crucial part in the energy management system. The topology processor must handle reading of the input data, treating the splitting and merging buses and their connectivity to the different circuits and proceeding to islanding and energizing analysis of the network. It has also to support all the types of substations configurations. In this paper, the difficulties and constraints...
This paper proposes a technique for shedding against voltage collapse (Under Voltage Load Shedding or UVLS) which is based on the optimal power flow procedure OPF with transient stability constraints (Transient Stability Constraints Optimal Power Flow TSC-OPF). To solve this problem we used a meta-heuristic approach to learn the method of Genetic Algorithms. The objective of this method is to get...
This paper aims to present the design of a computer code Transient Stability Code (TRANS_STAB_CODE) for the Transient Stability studies of electrical power systems under the influence of harmonics, using the GUI in MATLAB. The program was run for the loads are linear and nonlinear (Static Var Compensator (SVC), Thyristor controlled Reactor (TCR), and Unified Power Flow Controller ((UPFC)), After describing...
The paper presents an artificial neural-net based technique which combines supervised and unsupervised learning for on-line evaluating of power system static security. It automatically scans contingencies of a power system. The proposed approach allows the on-line security evaluation of (N - 1) contingencies by considering the pre-fault state vector. ANN-based pattern recognition is carried out with...
