This educational tool is composed of three modules: the software, the hardware and the interface modules. The software performs two tasks. It uses linear programming to optimize system components, and it ensures optimal energy flow via a designed controller. The hardware is a reduced model of a real green village, and the interface is based on a dynamic-link library using Visual C++ to do the connection between the hardware and the computer. The chapter discusses discuss the design and implementation of a laboratory model to help students understand the design and operation of hybrid renewable energy systems. This educational tool is based on three modules: the software, the hardware and the interface between the computer and the user operated hardware.

Pumped hydro storage (PHS) systems are used for both energy storage and generation purposes. Although hydropower is an established mean of power generation in the country for over 6 decades, a PHS project is yet to be implemented in Lebanon. The main objective of this paper is to design and examine the feasibility of a PHS power plant at an existing dam allocated in the mountainous area at altitude of around 1600m. The cost analysis for the project has been carried out taking into consideration local economic indices, and the costs of various system components including real estate prices. Results of the analysis show that a PHS project would be a very feasible investment because of the lower levelized cost and its high efficiency. Making use of an existing reservoir for storage has dropped the overall cost of the PHS project...

Quality education is currently a required component in the models of collaboration between Universities; yet the literature suggests that challenges remain in how the quality education will be practiced in a region that lacked for long time private universities. In this paper, we present an exploratory investigation to determine what could be learned by studying the practicalities of collaboration and accreditation of a newly established institution in Oman, namely, Dhofar University. The case study focuses on the practicalities of DU’s external collaboration, national accreditation, and good practices University-wide and within the College of Engineering in particular. The paper aims to present and analyze challenges, good practices, faculty a...

The rotor magnets are skewed with respect to the stator slots. In addition, the rotor is surrounded by a nonmagnetic conducting can made of inconel. This strengthens the rotor which otherwise has significant speed limitations due to centrifugal force. The effect of skewing the rotor magnets is ro reduce torque harmonics and noise-producing flux components. The effect of the rotor can is beneficial, in addition to increasing the operating speed of the machine. The solid canned rotor is very stable and easy to manufacture

The energy and environmental situations within these primary target areas reflect many similarities and share serious common problems. These include an almost total dependence on imported oil products as the primary energy source, rapidly growing populations that are escalating the demand for energy, and onlyrudimentary efforts currently underway to mitigate the greenhouse and other adverse environmental effects of energy utilization. Lebanon is highly urbanized compared to Syria and Jordan with much smaller area and has not been fully engaged in pilot projects for use of renewable energy. Applications of solar energy in that region have been growing since 1970. Solar water heating with support of policies in Jordan has achieved measurable market penetration. Lebanon and Syria have not made reasonable progress in solar applica...

The magnets can be nonradial, but an alternative strategy is radial magnets is with a significant skew. It that this arrangement leads to a drastic reduction in harmonics and cogging torques. The use of a supporting tube on the rotor whether magnetic or not, is also investigated with a view to overcoming problems of high-speed operation
