Adoption of solar thermal energy in the generation of electrical power in Iraq

Abstract

Iraq is characterized by its location near the solar band, and so it is distinguished by the high intensity of solar radiation and high brightness during the months of the year. This property made him able to use renewable energy sources in the generation of electricity, especially solar energy, for being the best and have pure effect. Implementation of a planned solar system with PTC collectors With the Hilla Gas station in (Abu Ghraj), Iraq, this site is characterized by this site has large tracts of land and proximity to the transmission network.

The nominal value of solar thermal energy proposed by the plant is 10 megawatts operating in the Rankin cycle using threminol VP1 (HTF) thermal oil as a working liquid. The average factory's power monthly is 9.99 megawatts. Capacity factor20.5 % proposed power plant comes out to be 36%. Four parabolic and twenty collectors were proposed to design power plant. In June, the production of system was 31.54 MW net on day. The electricity cost was 15.47 cents/ kWh. By comparing costs with traditional method based on fossil oils and renewable system previously working in Iraq, the suggested PTC system could vie well with the generation plants rest.
