1. Modeling, Control and Protection of Low-Voltage DC Microgrids
Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER
2. Planning Models for Single Wire Earth Return Power Distribution Networks
Sammanfattning : The high cost of grid extension to rural areas, often characterized by scattered communities with low load densities, requires the use of low cost electrification technologies to ensure economic viability. In Single Wire Earth Return (SWER) power distribution networks, the earth itself forms the current return path of the single phase system leading to significant cost savings on conductors, poles and poletop hardware compared to conventional systems.

3. Disruptive power : How distributed energy resources shape organizations and value logics in the future of electricity systems
Sammanfattning : The electricity sector faces its largest transformation since its beginning about a century ago. Combinations of ageing electricity networks, removal of fossil supply sources and electrification of industry and transport sectors require vast efforts at all levels of society. LÄS MER
4. On the Benefit of Harmonic Measurements in Power Systems
Sammanfattning : .... LÄS MER
5. On the hosting capacity of distribution networks for solar power
Sammanfattning : The future will bring changes in energy production and consumption that will affect the performance of electricity distribution networks. Electric vehicle charging will increase consumption; the installation of solar photovoltaic (PV) units will increase production. Both will change the energy flow and affect the power quality. LÄS MER
