Technical and economic modelling of grid-connected wind–hydrogen hybrid power systems of Yalova Armutlu district

Increasing of energy demand and beginning of consuming of fossil based energy sources forces mankind's hand research on clean energy. Studying on renewable energy resources like sun, wind, hydrogen, fuel cell, geothermal etc. is going on for solving energy problem. By its storable characteristic and areas of usage, hydrogen energy, is promising energy carrier, took part in on renewable energy resources. In this thesis, apart from classical methods which affect nature negatively, economical and technical analysis of generating of electricity from wind and hydrogen energy is investigated. Grid-connected wind-hydrogen hybrid system is modelled in order to supply energy requirement of a country by logging of wind velocity datas of year 2011 by a company that still continues to install wind energy parks in district Armutlu. By choosing one of five different types of wing turbines, where energy which is produced from power plant is more than energy requirement of the country, storage of hydrogen in tank is planned which is produced by electrolyser from residual energy. In cases of produced energy from power plant is less than energy requirement of country, energy generating is achieved by using of stored hydrogen in the fuel cell. In MS Excel programme modeling; costs of ingredient of system as wind turbine, electrolyser, hydrogen tank, fuel cell and in case where investment is done by using bank credit, by taking different bank credit rate into account, cost analysis is done and energy unit costs are analyzed. For example; energy unit costs are calculated as 0,056 €/kWh by choosing 2000 kW Enercon E-82 wind turbine, 500 kW electrolyser, 1240 kg 4 number hydrogen tank, 175 kW PEM fuel cell and %5 bank credit rate. Keywords: wind energy, hydrogen energy, energy economy, wind-hydrogen hybrid system, smart grid.
