Approach to decentralized optimal electric energy dispatch for the integration of several countries

An approach to international integration through coupling of two electricity markets in an attempt to minimize the operation cost of the global system, which connects both electricity markets via power exchange. The system is built, optimized and simulated using a new specific program, called Clymu, developed to reach this objective, which includes tools from SimSEE. Clymu uses independent simulations of both markets to determine the optimal power exchange which minimizes the difference between the weekly marginal costs of generation of both markets. The results obtained show that integrating markets by using Clymu reduces the global operation cost of the whole system and the vulnerability to variability of resources and prices in contrast with an operation policy that considers both markets independently.
