xxxii Introduction

Furthermore, the generation side stabilizing control approach allows the
downsizing of output and input filters while guaranteeing the operational
objectives of survivability in the presence of wide variations of load or
generation capacity.
In a nutshell, this book touches on the following areas:
• A systematic overview from a system integration perspective of the
interactions that might impair MVDC bus stability. The proposed
approach takes into account:
• The load type and its selected representation.
• The converter type used to interface the load and the sources
towards the MVDC bus.
• The impact of the selected regulation strategies in each converter
and the interaction between them.
• The proof of small-signal stability.
• The methodology for online stability assessment.
• A systematic overview of centralized and decentralized control theory
and its application on MVDC bus stability. This study takes into
account:
• The usage of linear state-space control methods for stabilizing
MVDC grids.
• The usage of robust control methods for stabilizing MVDC girds.
• The usage of nonlinear control theory and guaranteeing large-
signal stability by applying Lyapunov theory.
• The application of decentralized state estimation concepts for parti-
tioning the network in smaller subsystems.
• Important aspects that need to be considered before implementation
in a life-like environment of the selected control techniques. These
include the potential challenges which may originate from a nonideal
component behavior in a physical implementation, and verify that the
control techniques are successful in systems which exhibit high
dynamics
