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...

In this paper a new approach using Harmony Search (HS) algorithm is presented for placing Distributed Generators (DGs) in radial distribution systems. HS is used for multiple objective planning, to evaluate the DG placement and sizing by considering the power losses and voltage profile as objective functions. HS is operated on 12bus, 15-bus and 33-bus radial distribution system(RDS). Obtained r...

This paper presents a standalone hybrid power generation system based on low speed wind energy conversion system (WECS) using a variable speed permanent magnet synchronous generator (PMSG) with battery storage and diesel generator (DG). Different types of power management strategies are presents for minimal use of DG. For each PMS, mathematical model is developed based on the power balance (bet...

Received Jan 4, 2012 Revised Feb 12, 2012 Accepted Feb 14, 2012 The size of Distributed Generation (DG) is crucial in order to reduce the impact of installing a DG in the distribution Network. Without proper connection and sizing of DG, it will cause the power loss to increase and also might cause the voltage in the network to operate beyond the acceptable limit. Therefore, many researchers hav...

The use of renewable energy sources (RESs) is a need global society. This editorial, and its associated Special Issue “Grid-Connected Renewable Energy Sources”, offer compilation some the recent advances in analysis current power systems composed after high penetration distributed generation (DG) with different RESs. focus on both new control configurations novel methodologies for optimal place...
