BACKGROUND AND OBJECTIVES. Energy efficiency and energy saving are the priority direction of science, technology engineering development in Ukraine. The policy saving, carried out all over world, is directed to branches scientific researches spheres. big consumer resources higher school. Updating normative-legal technical base aimed at design operation buildings with low consumption high class ...

An operational cost minimisation model is established for a smart energy hub (S.E. Hub) consisting of combined heat and power (CHP) unit, heating, ventilation air-conditioning (HVAC) system, thermal electricity storage units. The optimal operation CHP with the load management HVAC under time-of-use (TOU) tariff. split ratio dynamically determined during operation. scheduling charging/dischargin...

The series Hybrid-Electric Drive (HED) architecture brings a significant range of potential benefits to military ground platforms. Electric-drive wheeled vehicles can feature electric traction motors in a conventional driveline, but also offer potential for motor incorporation into the axle or the wheel hub. The implementation of in-wheel hub drives presents challenges both in their design and ...

Introduction Many of today's energy infrastructures evolved during the second half of the twentieth century and it could be questioned if they meet the requirements of tomorrow. Besides congested transmission systems, many facilities are approaching the end of their prospected life time. In addition to that, other issues such as the continuously growing demand for energy, the dependency on limi...

Abstract This study focused on energy saving in hub system using smart grid technologies and management of the demand. The two-layer is proposed for implementing saving. In first layer, demand such as electrical, thermal natural gas are optimized subject to optimal level at day-ahead. Then, applied second layer reduction generation costs. optimization approach done by shuffled frog leaping algo...

Considering the problems of heterogeneous informa-tion system integration, service-oriented component of HUB-SOA model is proposed based on investigating E-HUB integration model and SOA integrated structure. Further, the key technical of the basic working principle, interface model, web service, system component and schema mapping are researched. What’s more, WEB service and its description of ...
