Abstract
Advanced power electronic converters can provide the means to control
power flow and ensure proper and secure operation of the future power
grid. The small electrical energy sources dispersed in electrical power
systems referred to as distributed generation are one of the most
significant parts of future grids - Smart Grids. The threephase, direct
matrix converter is an alternative solution to the conventional AC-DC-AC
converter for interfacing two AC systems in distributed power generation
with different voltage and/or frequency parameters. This paper presents a
control analysis of a threephase matrix converter employed as a power
interface of future electrical grids. The proposed system has been
successfully tested for bidirectional power flow operation with different
grid operating conditions, such as, frequency and voltage variation.
