EVALUATION OF ALTERNATIVES FOR POWER-SYSTEM COORDINATION AND POOLING IN A COMPETITIVE ENVIRONMENT

The paper defines and classifies essential issues that relate the need fdr electric power system coordination with the increasing developmen t of competition. Principles are formulated and a coordination model a nd a market structure are proposed, emphasizing the need for economic dispatch in the wholesale market. A detailed comparison is made of the market and pooling implementations developed in Argentina and Chile, countries that have pioneered the creation of competitive markets in t he electric energy sector. An evaluation of strengths and weaknesses o f those two implementations is included.
