A complex network approach for identifying vulnerabilities of the medium and low voltage grid
The vision behind the smart grid promises, among other things, to bring more attention to the lower layers of the distribution network where users are gradually transforming into prosumers. Independent of this transformation, users will expect the same (or higher) level of reliability of the infrastructure. In this paper, we consider physical samples from the Dutch medium and low voltage network ...

A dynamic virtual power station model comprising small-scale energy zones
Concerns over global warming and high oil prices are expected to lead to a continuous increase in electricity generated by distributed renewable energy sources and small-scale embedded generators (SSEGs). This increase in SSEG will pose numerous technical challenges for distribution network operators. The small-scale energy zone (SSEZ) concept seeks to overcome these challenges using appropriate ...

How to choose the cross-sectional area of the power cable
The choice of the cross-sectional area of the power cable is related to the investment, the loss and voltage quality of the line, and the service life of the cable. If the cross-sectional area of the power cable is too small, the voltage quality will drop, the line loss will be too large, and the initial investment will be too high. Therefore, the appropriate cross-sectional area should be ...

Integration of solar photovoltaic (PV) to LV distribution network: a case study
The development of renewable energy sources will increase the amount of generation connected to distribution networks. The main advantages are that optimally located distributed generation resources can reduce or postpone the need for investment in the transmission and distribution infrastructure; transmission and distribution losses are reduced as well as improvement in power quality and system ...

Powering up your business
Dramatic incidents such as explosions, fires, floods and landslides make the headlines, but mundane mishaps such as diggers cutting through cables can cause just as many problems for businesses. With many companies now putting all their eggs in one electronic basket, power supply is a critical factor in business life with the fear of electricity blackouts identified as a major problem for all ...
