RESUMO

In the previous structure of the Brazilian power sector, the economic model was such that the same company could provide generation, transmission and distribution services. In this model, services such as power reserve, reactive power support and transmission reserve, i.e., the so-called Ancillary Services to the operation of the electric system, were not considered explicitly. Therefore, no specific costs had to be paid as they were aggregated to the final energy price. In the new structure of the power sector, where each company provides a different type of service, the distinction of each Ancillary Service becomes a very important issue to the energy business. Once defined the service providers and users, it is evident the need of a market structure for selling and buying the service. This work suggests a market mechanism for selling and buying the Power Operative Reserve Service through a non-profit market agent. This proposal is based on the California`s Independent System Operator mechanism and, if properly adapted, can be applied to the Brazilian Power System. The main adaptations are: i) the adjustments of the sale price to allow a fair distribution of the economic advantage gotten with the purchase considering the interdependent markets, and ii) the adjustments of the sale price for the purchasers of only R1 and R2 reserves to affect only the prices of R1 and R2 and not the prices of R3 and R4.
