Optimasi Pembagian Beban pada Turbin Gas Blok 1 dan Blok 3 PLTGU PT. PJB UP Gresik Menggunakan Metode Iterasi Lambda Berdasarkan Base Point and Participation Factors

The operation of a good electric power system is needed in the generation system to obtain economical operating costs and optimal load sharing. Optimization of generation can be done by sharing the burden or economic dispatch to get maximum power with minimum costs. The method used is the lambda iteration based on the base point and participation factors for optimal load sharing. In this study, the lambda iteration method based on the base point and participation factors provide more optimal load sharing and lower operating costs than before. The optimal result of load sharing in the case of PT PJB UP Gresik PLTGU is the gas turbine 1.3 in Block 1 and the gas turbine 3.3 in Block 3. In Block 1, the average power generated by the 1.3 turbine gas turbine is 95,449 MW. In Block 3, the average power capable of generating gas turbines is 3.3 89,205 MW. The cost saved after optimization is obtained in the difference in Block 1 of Rp. 395.955.074,64 and Block 3 of Rp. 565.297.532,00
