| Resumo: | The growing global energy demand and the increasing social/political concern for the environment has driven the insertion of renewable energy sources (RESs) in the electrical power
system (EPS), such as photovoltaic systems and wind generation systems. Generally, these
sourcers are inserted in the EPS as distributed generation (DGs) systems in the new matrix
energy model organized by microgrids (MGs). MGs are small-scale networks composed of
sources based on DGs, electrical loads and energy storage systems (ESS). RESs are dependent
on meteorological conditions which make it intermittent and stochastic. To provide the energy
balance of these microgrids, it is necessary to integrate ESSs. Therefore, this work proposes a
cooperative control strategy to regulate the power flow of a DC MG with an interconnected ESS.
The proposed strategy coordinates the voltage control of the DC bus by Interlink CC (ILC) and
by ESS, providing power smoothing. To decouple the control loops from the bus, a Gaussian
inference function is used based on the information of the voltage deviation on the DC bus. The
proposed technique is validated through digital simulations and experimental tests. |
