“…World has suffered major blackouts in recent years and the researchers have proposed distributed generation (DG) as the solution for these major problems [2]. Distributed generation, also known as centralized energy, proposes the idea of on-site generation [3]. The best way to integrate DG in power system without redesigning the whole distribution system and saving a lot of money, is introducing a microgrid [4].…”

Due to the rapid increase in energy demand with depleting conventional sources, the world’s interest is moving towards renewable energy sources. Microgrid provides easy and reliable integration of distributed generation (DG) units based on renewable energy sources to the grid. The DG’s are usually integrated to microgrid through inverters. For a reliable operation of microgrid, it must have to operate in grid connected as well as isolated mode. Due to sudden mode change, performance of the DG inverter system will be compromised. Design and simulation of an optimized microgrid model in MATLAB/Simulink is presented in this work. The goal of the designed model is to integrate the inverter-interfaced DG’s to the microgrid in an efficient manner. The IEEE 13 bus test feeder has been converted to a microgrid by integration of DG’s including diesel engine generator, photovoltaic (PV) block and battery. The main feature of the designed MG model is its optimization in both operated modes to ensure the high reliability. For reliable interconnection of designed MG model to the power grid, a control scheme for DG inverter system based on PI controllers and DQ-PLL (phase-locked loop) has been designed. This designed scheme provides constant voltage in isolated mode and constant currents in grid connected mode. For power quality improvement, the regulation of harmonic current insertion has been performed using LCL filter. The performance of the designed MG model has been evaluated from the simulation results in MATLAB/ Simulink.

“…The integration of the Distributed Generation (DG) into the conventional EDS modifies the amplitudes of the fault signals (voltage and current), which significantly affects the accuracy of the fault localization algorithms [3]. For this reason, it is important to deal with this problem when there is presence of DG in networks [4].…”

The exact location of faults in the electrical distribution systems is a problem that affects not only the users, but also the companies providing the electric service. With greater time invested in this period, the losses due to unbilled energy and inconvenience to users increases, thus decreasing the quality of service. One of the causes of the growth in time is the misunderstanding that might exist in the localization systems that act under the presence of distributed generation sources in the distribution networks. In this sense, the present research develops an intelligent diagnosis of faults in distribution systems with distributed generation. Three stages are defined: Identification of the type of fault, the location of the zone, and the exact point of fault. A mixed method based on artificial intelligence and mathematical algorithms is applied. Eleven different types of faults that can occur in a distribution system are considered with six different values of fault resistances ranging from 5 to 30. The errors found are less than 2% in the location of the fault point with robustness to variations in the load and the penetration of distributed generation.

“…Actualmente, los SED están presentando penetración de Generación Distribuida (GD), la cual es universalmente aceptada como una solución efectiva y económica para responder a los incrementos en las demandas de energía del sistema, debido a que representa una mejor opción para corregir los problemas de pérdidas de energía, perfiles de tensión, problemas de cargabilidad de líneas, seguridad y confiabilidad, por mencionar algunos [4]. La integración de la GD a los SED convencionales modifica las amplitudes de las señales de falla (tensión y corriente) lo cual afecta significativamente la exactitud de los algoritmos de localización de fallas [5], por esta razón, este problema resulta de importancia tratarlo cuando existe presencia de GD en las redes [6].…”
