Impact of Hybrid Electric Vehicles in the Electric Utility System
Abstract: Abstract: The analysis breaks down the potential effects of the Plug-in Hybrid Electric Vehicles (PHEV) on the Portuguese electric utilization profile. The module vehicles will influence utility activities by including extra power request. There has for the most part been the desire that the lattice wouldn't be significantly influenced by the utilization of these vehicles, in light of the fact that the energizing would just happen amid off-top hours. A …

Analysis and Testing Methods for Solar Thermal Evacuated Tube Collector: A Review
Abstract: Evacuated tube receiver used with parabolic trough collector can be characterized in terms of their heat loss and their optical efficiency. The optical efficiency of the collector involves reflectivity, transmissivity, tracking accuracy, shading by receiver tube surface, shape and absorptance of the material used. On the other hand, receiver tube heat loss includes conductive, convective and radiative losses. Here, in case of evacuated tube, major losses are through radiation, the …
