This paper identifies the risks for the functionality and reliability of the grid that arise from the integration of the transport and supply chain. The electrification of transport is a promising option for the transition to a low carbon energy and transport system. But on the short term, the...

The operation of wind turbines in the distribution networks may affect the power quality offered to the consumers. One of the most important considerations is the effect on the voltage profile, i.e. the induced slow voltage variations, which are the subject of this paper. Two alternative...

The clustering coefficient, path length and average vertex degree of two urban train line networks have been calculated. The results are compared with theoretical predictions for appropriate random bipartite graphs. They have also been compared with one another to investigate the effect of...

A reconfigurable network can change its topology by opening and closing switches on power lines. We use real wind, solar, load, and cost data and a model of a reconfigurable distribution grid to show that reconfiguration allows a grid operator to reduce operational losses as well as to accept...

Locational pricing can reduce the investment needs arising in distribution networks from the transformation towards smart grids with high shares of renewable generation. We analyse different approaches. Locational signals in a general tariff plan for either energy or network pricing require...

Plug-in electric vehicles (PEV) are emerging as an efficient and sustainable alternative for private and public road transportation. From the point of view of electric grids, PEVs are currently considered as simple loads due to their low market penetration. However, as the PEV fleet grows,...

This paper investigates the role of distribution networks in explaining incumbency advantages in the European car market. We compare three approaches to incorporate the size of distribution networks in discrete choice models of product differentiation: as an extra product characteristic, as a...

Electrical power systems have been traditionally designed taking energy from high-voltage levels, and distributing it to lower voltage level networks. There are large generation units connected to transmission networks. But in the future there will be a large number of small generators connected...

Distribution activities have been the least studied domain of the electricity sector; over the last few years though, strong debates emerged with regards to the future. Indeed, this activity might soon undergo some deep structural changes, particularly as smart technologies are deployed: theses...

In systems experiencing water scarcity and consequent intermittent supply, users often adopt private tanks that collect water during service periods and supply users when the service is not available. The tank may be fed by gravity or by private pumping stations depending on the network pressure...
