Cost Function Thermal Generator The fuel cost equation of each plant is obtained by multiplying the generator's input-output equation at its fuel price. Then the full fuel cost equation is shown in the following table. To calculate the cost function of each thermal generator, first calculating the input outpu characteristics of each thermal generator. The input-output equation can actually be obtained with the help o MatLab, and is displayed in the following input-output characteristic table.

Table 3. Real Thermal Generation Expenses at night peak loads From the analysis result for the second case that is the peak of nighttime load condition before optimized, the generating load charged to the thermal unit is 435.3 MW, with total generation cost of IDR 140,806,274.24. Losses generated before optimization amounted to 26,299 MW. The total system load is 532.3 MW. Fourhydro power plants bear respectively: PLTA Bakaru 126 MW, PLTM TeppoPinrang 0.3 MW, PLTA TangkaManipiSinjai 3.5 MW, PLTMBili-Bili 7.1 MW. Furthermore, by using the proposed method is by using the intelligent method based on Ant Colony Optimization (ACO) obtained a more optimal generation results. As a comparison, thetechnique in this study used Lagrange method. More is shown in Table 4 below.

Figure 3. Comparison of the cost of raising the peak of nighttime load are maximized because those are the cheapest generation. The Sengkang PLTGU power plant unit acts as slack bus in this system, which generates the most expensive thermal generation cost of IDR 71,509,642.449 px hour, with generated power of 166,102 MW. While the cheapest thermal generator unit at MaleaMakale pow plant is IDR 1,460,445.245 per hour, with a raised power of 3,520 MW.
