This research focuses on modelling large-scale power system using DC load flow approach in Indonesia electricity market which consists of two primary power system, i.e. Java-Bali and Sumatra power system. This study adopts the 26 nodes stylised model for Java-Bali power system and eight nodes stylized model for Sumatra power system, by incorporating generation, transmission and power system stability constraint. The study in this paper is the first electricity market modelling to study Java-Bali and Sumatra power system using perfect competition and oligopoly strategic behaviour. This paper simulates the effect of electricity market restructuring in power generation market in Indonesia power system. By using market modelling, i.e. perfect competition and Cournot oligopoly market, this research determines the optimal market structure, effective generation mix in the generation companies, and an effective number of the competitive electricity market. This preventive approach contributes to the current literature in electricity market modelling and market power studies, which is essential for Indonesia, when and if the market restructuring occurs.
