Abstract :
The physical guarantee of a power generation
plant corresponds to the minimum amount of energy that
the plant can guarantee in an unfavorable scenario of
inflows, based on historical data. It is, therefore, the
amount of energy that the plant can commit in its sales
contracts or self-consumption. The rules of the Brazilian
electricity market allow a seasonal distribution of the
physical guarantee of each plant. Seasonalization process
consists in converting the average annual values of the
plant physical guarantee into monthly values. The
generator must declare the seasonalization of the physical
guarantee annually, in December, at the Electric Energy
Commercialization Chamber (CCEE). The decision on
how to realize the seasonalization over the following year
is made in an uncertain environment, as it depends on
unknown initial data, such as future energy prices and
the allocations of the Energy Reallocation Mechanism
(MRE). This work proposes a strategy for seasonalization
of the physical guarantee of a set of power generation
plants based on models of multicriteria decision-making
under information uncertainty
Keywords :
Energy seasonalization, multicriteria decision making, uncertainty factor, robust solutions, general decision making scheme.
