Economic dispatch of IEEE 26 bus with transmission losses employing a modified cuckoo optimization algorithm (MCOA) method

Economic Dispatch (ED) serves as an important mechanism, advantageous for controlling and operating. The core function of ED lies in the scheduling of the generation system, currently operating or running in each generating unit to minimize the need for load. The research system in this study was conducted by implementing the Modified Cuckoo Optimization Algorithm (MCOA) method, then compared with the Cuckoo Optimization Algorithm (COA) method. The considered values include load power, generator and power losses in the cost calculation. The system was tested for 10 times and analyzed to produce a generator power value and generator cost. The comparison results of the minimum MCOA were generator power of 1277 MW, a maximum of 1315 MW, and an average of 1293 MW, while the COA produced a minimum of 1278 MW, a maximum of 1341 MW, and an average of 1294 MW. At the MCOA, the cost generation was obtained at a minimum value of 13716 $ / day, a maximum of 14590 $ / day and an average of 14085 $ / day. Meanwhile, the COA was at a minimum value of 13801 $ / day, a maximum of 14694 $ / day and an average of 14301 $ / day. The last step was performed to reduce the value, in which MCOA method obtained a result of 85 $ / day or 0.80%, which was cheaper than the standard COA method. In addition, comparisons were conducted, indicating the result that the MCOA method was deemed successful during the 10 system trials in performing cost optimization better than COA in generating minimum costs.
