Suplementação de receita em rateio de custos em sistemas de transmissão de energia elétrica via otimização.

Abstract

The aim of this thesis is to describe a procedure to calculate a set of tariffs of use of the transmission system, based on marginal costs. Due to the economy of scale characteristic of the expansion of the transmission system, the marginal costs are smaller than average costs,without remunerating investments accomplished in the transmission system. As a consequence, these tariffs based on marginal costs need to have a supplementary adjust. This thesis describes a new way to evaluate this supplementary remuneration, based on a minimum change in the tariffs obtained with the marginal method, in that all of the users of the transmission system contribute to this supplementation, depending on the degree of the loading on the electric grid close to this user. It is proposed also that losses factors contribute in the definition of these marginal tariffs.
