Inclusion of solar energy in iraq gas-turbine power plants as a method of solving the country's energy system shortage

Abstract

At high ambient temperatures, the performance of gas turbine power plants drops significantly. Technical solutions of compensation for losses associated with the constant injection of water into the air intake of a gas turbine. This approach is not acceptable in regions with limited fresh water reserves. Radical solutions are required to reduce the cost of generated energy. Integrated Combined Solar Cycle (ISCCS) technology has proven itself on many projects. The addition of a combined cycle gas cycle with solar energy can significantly increase the overall efficiency of the power plant. Despite the increase in costs during the construction of its solar part, the total cost of operating solar collectors is several times less than a turbine installation. Given the global trend to fight carbon emissions, switching to a hybrid scheme is economically attractive. Trading in carbon credits for CO2 emissions will significantly reduce the payback period for the construction of gas turbine modernization under the ISCCS scheme. This paper presents an option to modernize a gas turbine power plant in the city of Basra (Iraq), using the advantages of solar radiation and recycling of combustion products from gas turbines. It is proposed to equip the existing 200 MW gas turbine plant with two steam turbine units with a capacity of 75 and 65 MW, working in conjunction with solar collectors producing low pressure water vapor. Due to modernization, the efficiency of the power plant should increase from 38% to 55%. The revision of the schematic and technical solutions of Iraq power plants will allow producing sufficient energy for the region.

Survey about impact voltage instability and transient stability for a power system with an integrated solar combined cycle plant in Iraq by using ETAP

“…V. TRANSIENT STABILITY ANALYSIS Definition of the system response due to different disturbances which are the source of instability i.e., which lead to loss of synchronism or stopping or overloading of generators and motors. Switching transients are mostly related with go wrong of circuit breakers and switches, switching of capacitor banks and other frequently switched loads [7][8][9][10][11][12]. In this paper we show the stability of system when it loses one of its loads (Rumaila field 22MVA) fig.…”

“…About 70% of the total electricity produced in 2013 was lost, which includes both technical, commercial and administrative losses (Transmission-6%, Distribution-13%; theft and non-billed-23%; Non Collected 26%; and collected 33%). Over 90% of the losses are in the distribution network of which 79% are losses not technical (theft or not billed and not collected energy) [5][6][7][8][9][10][11].…”

The Use of Floating Solar Panels in Hot Regions Such as Iraq to Benefit in Cooling the Panels and Increasing Their Efficiency

“…Marsh Al-Dalmach or Hor Afak is a large water body in Iraq that feeds from the general downstream drainage between the Tigris and the Euphrates, and is located between provinces Diwaniyah to the west and Wasit to the east with area about 120,000 dunum (300,000,000 m 2 ) [12]. Iraq is a region rich in solar energy, where the sun's brightness increases more than 4000 hours a year [13,14]. In this paper, we will study the effect of temperature on the performance of solar panels and choose the marsh area in order to take advantage of the breeze phenomenon or (continentality).…”

Eliminate the Migration of Farmers to Cities by Supporting Renewable Energy Projects

“…And to implement the idea, the well-known HOMER pro. program was used, which deals with accounts and clean energy plants [7][8][9][10][11][12][13].…”
