Distributed Generation (DG) based on Renewable Energy Sources (RES) are considered as an effective and economical technology for the advancement of Electric Power System (EPS) to fulfill load demand. Mostly, studies pertaining DG planning performed while considering constant demand generation. However, these considerations may provide misleading inconsistent values loss reduction, voltage profi...

Few years ago Power Systems consisted mainly of large generation plants supplying distant loads through the utility grids. The last years, though, a number of factors lead this structure to change gradually. Small generators of some MW have been already dispersed (DGs) throughout the transmission grid. The distribution of smaller generation units throughout the distribution system as near as po...

Wind energy offers a significant advantage such as no fuel costs and no emissions from generation. However, wind energy sources are variable and non-dispatchable. The utility grid is able to accommodate the variability of wind in smaller proportion along with the daily load. However, at high penetration levels, the variability can severely impact the utility reserve requirements and the cost as...

The emergence of distributed generation such as solar systems has introduced new challenges in distribution networks that are becoming more apparent with increasing penetration levels. time mismatch between peak load and can make voltage levels swing towards extreme limits during a day. Distribution network service providers struggling to cater for installations while ensuring the quality stead...

Distributed energy resources, such as electric vehicles and roof-top solar panels have become increasingly popular essential components of power distribution systems. However, their growth poses significant challenges to system operation, bidirectional flow, intermittent generation, increased peak demand, unexpected frequency/voltage fluctuation. To tackle these challenges, we developed a vehic...

The Distributed Generator types have different combinations of real and reactive power characteristics, which can affect the total loss voltage support/control radial distribution networks (RDNs) in ways. This paper investigates impact DG’s penetration level (PL) on profile RDNs based DG types. are modeled depending they inject. profiles obtained under various circumstances were fairly compared...

Due to the increasing penetration of distributed generation, storage, electric vehicles and new ICT technologies, distribution networks are evolving towards the Smart Grid paradigm. For this reason, new control strategies, algorithms and technologies need to be tested and validated before their actual field implementation. In this paper we present a novel modular distributed infrastructure, bas...

The focus of the European Union (EU) energy policy is on the promotion of low-carbon technologies and renewable-energy sources. In pursuit of this target, EU countries are setting up adequate support schemes (e.g. feed-in-tariffs). This is giving rise to different generation technologies and growing share of small scale generation in power networks. The paper deals with the impact of distribute...
