This work analyses the configuration and operation principles of hybrid wind-hydro power plants with pumped storage integrated into autonomous electric grid systems, in order to support high wind energy penetration. The plant consists of wind generation units, combined with a pumped-hydro storage system. It operates on a daily basis, storing the surplus wind production by pumping water in an el...

the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...

Electric power systems with substantial wind capacity require additional flexibility to react to rapid changes in wind farm output and mismatches in the timing of generation and demand. Controlled variable-rate charging of plug-in electric vehicles allows demand to be rapidly modulated, providing an alternative to using fast-responding natural gas plants for balancing supply with demand and pot...

They are known operational limitations that cause the electrical system of a ship, the starter of electrical bow thrusters. Normally during this operation has appealed to generator dedicated exclusively to such motors, for this purpose, or dispose of any of the auxiliary power plant off the bar bus and thus limiting the consumption of power available inside the ship. This way of design or opera...

Operation of the electric power systems must fulfil economical demands while meeting the safety limits. Operating is influenced mainly by two factors — relation to safety and efficiency. Although they are contradictory, both aim to remove the unacceptable risk and determine the optimum of system output. The article describes the use of mental models for operating the process systems. A simple m...

Optimization of specific power of axial flux permanent magnet brushless DC (PMBLDC) motor based on genetic algorithm optimization technique for an electric vehicle application is presented. Double rotor sandwiched stator topology of axial flux permanent magnet brushless DC motor is selected considering its best suitability in electric vehicle applications. Rating of electric motor is determined...

The paper examines design and operating data of current concentrated solar power (CSP) 10 solar tower (ST) plants. The study includes CSP with or without boost by combustion of natural gas 11 (NG) and with or without thermal energy storage (TES). The study then reviews the novel trends to 12 produce better ratio of solar field power to electric power, better capacity factor, better matching of ...
