Dynamic Economic Dispatch for 150 kV Sulselbar Power Generation Systems Using Artificial Bee Colony Algorithm

Managing power generation is very important in the process of distributing electrical energy to consumers to get optimal power generation in the system with minimum cost. In this study, an Artificial Bee Colony algorithm is proposed to get the best economic dispatch solution for the 150 kV Sulselbar electric system in Indonesia by considering losses, generation limits and ramp rate for each unit. Simulation results from the same system are compared with the Lagrange method which only considers the generator power limit. Besides that, voltage stability of the system is also evaluated using the L index including the loading margin on buses which are considered weak. Results have shown the proposed method (Artificial Bee Colony algorithm) is able to provide the best solution for dynamic economic dispatch to the observed system.
