Utilizing PV System for Auxiliary Energy Demand in Conventional Power Plant

The purpose of this study is to investigate the utilization of PV feeding system for auxiliary energy demand in the conventional power plants. A 573 MW tri-fuel power plant in Jordan IPP3 the largest internal combustion engine (ICE) power plant in the world is the case study to evaluate the energy economy aspects of PV feeding system and its effects on the monthly payments for this energy. All relevant computations will be performed in order to end up with reasonable, feasible and applicable results. The auxiliary energy demand of this power plant while no operation is covered from the national transmission grid which results in around 48 MWh imported energy on daily basis taking in mind no operation case. Therefore, such PV system will have a noticeable impact over the productivity of the whole plant as well as raising the money spent for fuel upon the reduction of the heat rate. The PV system is sized to have a capacity of 2 MWp planned to be utilized during the day time. Considering the imported energy benefit, the corresponding pay-back period will through the 5th year where is expected to be accomplished during the 7th year when it comes to the heat rate improvement. The prominent fact to be mentioned here that the pay-back period upon either imported energy benefit of heat rate improvement is calculated separately.
