CALCULATION OF VOLTAGE THRESHOLDS FOR SOURCE SCHEDULAING IN A

Abstract

The nanogrid is a small scale power system that
consists of renewable and non-renewable power resources
that supply power to nearby loads. The control structure of
the nanogrid aims to schedule the sources, such that the
non-renewable source improves the system reliability
during the long-term shortage of the renewable source.
This is achieved by Dc-Bus Signaling (DBS) to reduce, as
much as possible, the participation of the non-renewable
sources in the electricity generation process, taking the
maximum advantage of the renewable sources available.
This paper presents the control method used for source
scheduling of a nanogrid, and it also develops an algorithm
that calculates the voltage thresholds for each source
which satisfies the aimed scheduling.
