| Resumen en otro Idioma | In this paper a centralized control strategy for the 10
efficient power management of the power converters conforming a
hybrid distributed generation microgrid is explained. The microgrid
is based on a DC and an AC bus. The study is focused on the converters
connected to the DC bus. The proposed power management
algorithm is implemented in a microgrid central processor. This 15
algorithm is based on assigning several operation functions to each
of the generators, loads and energy storage systems in the microgrid.
A communication system is used to assign the operation functions
to each of the microgrid elements. The power flows between the DC
and AC buses are studied in several operation scenarios, in which 20
the proposed control can be verified.
Experimental and simulation results demonstrate that the algorithm
allows to control the power dispatch inside the microgrid properly,
by performing the following tasks: (1) the communications
among power converters, the grid operator and intelligent loads, (2) 25
the connection and disconnection of loads, (3) the control of the
power exchange between the distributed generators and the energy
storage system, (4) the compliance of the power dispatch limit set by
the grid operator, (5) the synchronization with the grid and (6) the
control of the voltage at the DC bus. |
