Abstract:
The availability of methods and devices to support the
implementation of the Smart Grid represents the real key point
to design modern power networks, both for large size and for
local distribution systems (Microgrids). Efficient management of
energy flows and the exploitation of the renewable energy sources
can be carried out using smart power electronic interfaces. The
interaction of multiple power converters among sub-grids or
grids and distribution nodes can give rise to not trivial stability
issues. The experimental dynamic characterization of power
converters represent a critical issue in micro power systems
analysis. It allows to evaluate not only performances of power
circuits in terms of bandwidth, transient response, etc, but also
their dynamic influence on the whole system.
Techniques for loop gain measurements are well established and
usually adopted in test procedures. Not so for the experimental
characterization of input and output closed loop transfer
functions, which imply the use of auxiliary circuitry to inject
small signals upon the steady state values in high voltage or with
high output current. The paper discusses different approaches to
dynamic measurements and proposes some actuators for signal
injection. Experimental results are provided.
