Smart grid is the most significant topic in power system due to numerous benefits. integration of distributed generation. DG plays an important role different configurations either connected mode or islanded mode. Multiple will result fault currents this may lead damage existing protective devices. In paper Fuzzy used optimally locate and Jaya a new optimization technique adapted size Fault cur...

There is a huge requirement for power systems to reduce losses. Adding distributed generators (DGs) the most common approach achieving lower However, several challenges arise, such as determining ideal size well location of utilized generators. Most existing methods do not consider variety load types, and DGs besides reducing convergence time enhancing optimization results. The paper performed ...

: Distributed generation (DG) sources are becoming more important in electrical networks due to the increase of energy demands. However, DG can have a profound effect on network power loss. Hence, optimal placement and size DGs extremely important. This study presents backtracking search algorithm (BSA) based multiple within distribution systems so reduce The BSA is new heuristic algorithm. Two...

Distributed generation (DG) offers several benefits to the electrical system, such as reduction of losses and improvement voltage profile. DG can be maximized when allocation sizing are optimal — a problem known Optimal Sizing Placement Generation (OSPDG). This paper presents new meta-heuristic that associates PSO (Particle Swarm Optimization) with L´evy flights (LF) solve OSPDG, identified in ...

Energy consumption and environmental issues have become major drivers of increasing renewable energy penetration levels. The electricity generated from sources is decentralized throughout distributed generation (DG), which located at the distribution level. However, presence DG can change system characteristics affect protection systems. Thus, this study aims to investigate impact in term its s...

The necessity of Distributed Generation (DG) in the modern power system has increased greatly. Optimal placement and sizing DGs have a significant impact on objectives voltage stability enhancement, real reactive loss minimization security reliability. Different types such as Type I, II, III IVare placed. optimal these is found using Voltage Stability Index (VSI). done Differential Evolution (D...

Electric distribution networks have a simple protection system including fuses, re-closers, and overcurrent relays. One of the negative effects of DG installation in distribution network is miscoordination of protection devices and conflict between DG operation as islanding mode and protection purposes. This paper for overcoming to this difficulty proposes an efficient algorithm based on dividi...
