Isolated grid diesel-based systems have been a basic electricity system in islands in developing countries. Nevertheless, the increasing diesel price and the higher cost of diesel transport to a long distance to the remote islands make the diesel-based systems unsustainable. This study analyzes...

The purpose of this study is to assess the policy-relevant effects of incorporating a more proper representation of electricity transmission in multi-sector national policy models. This goal is achieved by employing the KAPSARC Energy Model (KEM), which is the first publicly available...

This paper aims to study the effect of augmented Distributed Generation (DG) penetration in the basic indices of the distribution network (voltage, angle, power flow, thermal fatigue of cables). For this purpose, a realistic expansion of an existing distribution grid is considered, after looking...

In photovoltaic system connected to the grid, the main goal is to control the power that the inverter injects into the grid from the energy provided by the photovoltaic generator. The power quality injected into the grid and the performance of the converter system depend on the quality of the...

This article presents a non-conventional design approach of high order passive filters incorporated with distributed energy grid integration systems based on particle swarm optimization (PSO) as one of multi-objective evolutionary search algorithms. Two topologies of passive grid filters (third...

Grid integration remains one of the key challenges related to the worldwide expansion of distributed renewable energy systems. This paper presents innovative measures for increasing the hosting capacity of distribution grids with a focus on the medium-voltage grid, based on representative...

In this article the research results of application of back-to-back HVDC system in the Tomsk electric power system are presented. Historically, power transmission between the South to the North parts of the Tomsk electric power system is realized via the long double-circuit 220 kV overhead...

On august 31, 2014, a generalized power outage impaired the Tunisian power system. This event was particular in the time frame of the cascaded failures, where weak cross-border grid interconnection stood out as a determinant factor. North African interconnections did not support the Tunisian...

In 1988, when the idea of economic liberalism was spreading across nations, the United Kingdom opened an electricity market. Soon, to increase the operational efficiency, other countries followed suit and gradually induced free competition to the electricity market. The reform aims to liberalize...

The penetration of renewable energy sources into power systems has been increasing to mitigate the concerns for the environment, global warming, and rising fuel prices. However, the variability and uncertainty of power output from renewable energy sources raise challenging issues for power...
