Definition of an efficient transmission system using cooperative games theory

Under a context of transmission open access, a methodology to define a common transmission trunk system using economic and technical criteria is proposed. A transmission trunk system is defined as a unique and common system constituted by electrical lines and substations that are economically efficient and necessary to allow the development of an electrical market and the supply of demand in the respective electrical system at a minimum cost and in an efficient manner. The principles of cooperation and interaction between agents that are the base for the cooperative games theory are used. Simple games and the Shapley value approach are used. The proposal responds to the need to identify a common main system, common to supply and demand agents, needed in system open access schemes in electricity markets.
