In Mexico most of the electrical power systems in the petrochemical industry accommodate generating units. The power systems of these industrial plants were initially designed to operate isolated from the utility grid and the amount of the generation capacity used to be twice the value of the maximum expected demand. Due to changes in the Mexican legislation allowing the use the transmission grid for wheeling the surplus of power generated to another industrial facility of the same owner many of these isolated power systems are being interconnected with the utility grid. As a result of this, the operators of those industrial systems are facing some problems never experienced before. The purpose of this paper is to assess the dynamical behavior of an industrial power system with co-generation units following to the loss of a portion of on-site generation and the sudden loss of the interconnection with the utility grid.
