Operational Cost Reduction of Gas-Thermal Power Plant Based on Bat Algorithm

Abstract

An optimised operation of a thermal power plant is required to optimise fuel consumption cost. It is still high and becomes a problem of economic dispatch in the operation of the plant. Load scheduling and generator capacity are needed to get optimal plant operation, especially energy usage. This paper presented a thermal power plant operation analysis to obtain optimum operational energy costs using the Bat Algorithm (BA). The actual data of 6 thermal power plants to serve the peak loads in 2018 is used for the calculation. The problem solution is simulated and calculated using maximum (95%) capacity and the BA method. The Simulation is done by using MATLAB software. The generator unit and generator load characteristics are collected to obtain objective functions and constraint functions. BA completes this function to get the lowest energy. The BA method will be compared with the calculation of real-time energy generation without BA to analyse its accuracy. The total operational cost of the actual power plant without BA is $ 1,988,410. BA simulation gave the total energy cost is $1,653,374. So, the generated energy savings is 16.85%, or 335,036 MW reduction.

Induced roll magnetic separator applied for high grade ilmenite separation from mining tailing

“…In the near future, several options of modeling approach used MATLAB software can be developed for process optimization in relation to ilmenite recovery. As Sofwan [36] applied BAT Algorithm with MATLAB software to reduce the operational cost of a power plant, with regard to this matter the operational cost of IRMS for ilmenite recovery can be decreased by considering some factors (gravitational effects in shaking table, chemicals used in froth flotation, particle size in round screen, and oven drying temperature) in the application of BAT Algorithm. On other occasion, Romahadi [37] used Bayesian Network for process optimization of heat exchanger with MATLAB program, this computational approach can be implemented to optimize the ilmenite separation from cassiterite tailing in the IRMS by controlling some parameters (feeding input, opening adjustment, single or double splitter) in a mathematical modeling.…”

“…Energy needs have become human needs in the word because energy is covered all aspect of everyday human life. In Indonesia, the government have the project to increase domestic electricity generation capacity by 35,000 MW [1]. In the steam generator, chemical energy available in fossil fuel is converted to heat energy by combustion.…”
