Abstract: Many small power producers (SPPs) exist in the power market worldwide. Some of which established their owned grids to transport electricity to customers directly leading to the complexity in electricity market structure under multi-owned integrated distribution system. This paper aims to equilibrate a decision strategy to encourage the asset sharing of the distribution grids among the distribution owners and to introduce a conflict management model to avoid the employment of the complex wheeling methods to the various distribution owners of the combined system. A numerical simulation shows that the equilibrium point is on the strategy that the common asset must be shared among all players. Every network user is then at a level playing field with a fair and equitable responsibility to the distribution system based on their actual usages.

Keywords: Competitive market, distribution system, game theory, investor-owned utility, unbundling
