CALDERON-GUIZAR, J.G.. Transient Stability Studies on Industrial Power Systems Interconnected to the Transmission Grid. Ing. invest. y tecnol. [online]. 2010, vol.11, n.4, pp.445-451. ISSN 2594-0732.

Aiming to ensure continuity in the electrical supply to critical processes, the electrical systems of large industrial plants, i.e. gas, and petrochemical industries usually posses local generation. Should the local generation be enough to satisfy the demand of the plant, then the interconnection with the public grid is commonly used as an important support for emergency conditions. This paper is concerned with the dynamical performance of two interconnected industrial power systems tied to the transmission system. Simulation results indicate that the frequency performance of one of the industrial plants, after the transients caused by the loss of the tie with the transmission system have died out, is greatly improved if both industrial plants remain connected after the disturbance.
