a hybrid hydro/wind/photovoltaic base on hydrogen storage system is designed to supply power demand of pump stations. the aim of this design is minimization of net present cost of the hybrid system. optimization problem is subject to reliable supply of the demand. the system is investigated in the north west of iran (meshkinshahr) and the local data is applied. about 12 pump stations are found ...

This paper introduces a novel concept of mini-hybrid solar power plant integrating a field of solar concentrators, two superposed Organic Rankine -CyclesIORC) and a (bio)Diesel engine. Turbines for the Organic Rankine Cycles are hermetic scroll expandergenerators. Sun tracking solar collectors are composed of rows of flat mirroi bands (CEP) arranged in a plane, which focus the solar energy onto...

. As the power dissipation becomes an important design constraint, especially in embedded systems, early and accurate power estimation is compulsory. The early power estimation dictates the design to meet the required specifications. In this paper, we describe efficient power modeling technique for embedded processors at higher level. We also present power models of two different processors usi...

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...

For the past 10 years, I have been working as an electrical engineer for Helixx, a recently established car-manufacturing company, on hybrid electric vehicles. The current project is a P2 hybrid, an expansion on the power-split hybrid model that could “provide 95 percent of the fuel efficiency benefits of an expensive two-motor system, like the one in the Toyota Prius, [a power-split hybrid], b...

Renewable energy provides twenty percent of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It is a renewable source of energy and provides almost one-fifth of electricity in the world. Also, it generates electricity using a renewable natural resource and accounting for six percent of worldwide energy supply or about fifteen percent of th...

This study shows the design of a new hybrid power generation system, photovoltaic panel (PV)–coupled solid oxide fuel cell (SOFC) and gas turbine (GT)–electrolyser. Three objectives (cost, pollutant emissions, and reliability), which are usually in conflict, are considered simultaneously. The design of a hybrid system, considering the three mentioned objectives, poses a very complex problem of o...

This paper investigates development of power management strategies tailored specifically to a medium truck with parallel hydraulic hybrid powertrain. The hydraulic hybrid vehicle (HHV) system is modeled in MATLAB/SIMULINK environment. As the starting point, this study considers rule-based power management strategy adopted from the previous HEV study. Dynamic Programming (DP) algorithm is used t...
