The growing demand for energy is common in both developed and under
developing countries, because of the continuous population increase or the very
progress of these countries. To meet this demand we must attend to the commitment
of a clean and renewable generation of energy, aiming to reduce greenhouse gases
and more severe socio-environmental impacts. Although the energy matrix of Brazil is
predominantly hydraulic, the level of useful volume of the reservoirs has been showing
smaller and smaller over the years, with a tendency to reduce the storage capacity. In
this context, this research suggests a study concerning the joint operation of Irapé
hydroelectric plant, which has 360 MW with a 120 MW photovoltaic power plant, in an
attempt to evaluate the contribution of additional energy storage in the form of water
level. With this, it was possible to observe that, for a photovoltaic power equal to that
of a hydraulic turbine, the complementary generation was 258,045.30 MWh.year,
contributing to a better predictability of the hybrid generation and to optimized use of
the natural resources. The capacity factor of the hydroelectric plant went from 13.79%
to 21.98% with the integration of the solar photovoltaic power plant. The reservoir had
its total capacity restored over a period of 11 months of joint operation. An economicfinancial analysis was carried out to evaluate the feasibility of implementation,
considering a revenue based on the remuneration of the settlement price of the
differences (PLD) in the hourly basis. The estimated implementation cost regarding the
PV plant was 2.86 R$ / Wp, from which the financial model obtained a 15.5% IRR and
a positive NPV, thus indicating that the photovoltaic energy source has the potential to
be privileged in this model. |
