This paper addresses the creation of a reduced weakly meshed network containing the basic information for applying suitable numerical techniques for solving specific issues related to the distribution system reconfiguration for large real Medium Voltage distribution systems. In particular, the structure of the network and the installed components (connections to the High Voltage supply system, ...

Network reconfiguration is the process of changing the topology of distribution system by altering the open/closed status of switches to find a radial operating structure that minimizes the system real power loss while satisfying operating constraints. This paper proposes an efficient algorithm based on Plant Growth Simulation Algorithm (PGSA) and Self Adaptive Hybrid Differential Evolution (Sa...

In low-voltage grids with a wide spread of domestic and/or small commercial consumers, mostly single-phase, problems can appear due to unbalanced power consumption between the different phases. These are mainly caused voltage unbalances phases and increase in distribution losses. This phenomenon occurs more frequently at end highly radial be stressed by installation renewable generators next co...

This paper presents a new method to detect high impedance faults in radial distribution systems. Magnitudes of third and fifth harmonic components of voltages and currents are used as a feature vector for fault discrimination. The proposed methodology uses a learning vector quantization (LVQ) neural network as a classifier for identifying high impedance arc-type faults. The network learns from ...

This paper presents a fuzzy multi-objective approach for achieving the minimum active power loss and the maximum voltage magnitude in order to improve the efficiency of radial distribution networks with distributed generations. Multi-objective function are considered for load balancing among the feeders, minimization of the real power loss, deviation of nodes voltage, and branch current constra...

Network Feeder Reconfiguration is the process of altering the topological structure of distribution feeders by changing the open/closed status of the tie and sectionalizing switches. In this paper, the Network Reconfiguration problem will be formulated as multi objective optimization problem with equality and inequality constraints. The proposed solution is based on optimization algorithms know...

Monitoring, protection, and control processes are becoming more complex as distributed energy resources (DERs) penetrate distribution networks (DNs). This is due to the inherent nature of power DNs bi-directional flow current from various sources loads. To improve system’s situational awareness, grid dynamics entire DER integration must be carefully monitored using synchronized high-resolution ...
