The new trend in power systems is developing towards Distributed
Generation (DG) due to some technical, economical and environmental
reasons. However, the large number of the renewable based
Distributed Generation integrated into the power system and the wide
application of power electronics, presents a great number of
challenges. In addition, DG based smart power grid requires M2M-like
communication scenarios, in which the role of M2M as well as its
efficiency for the protection of distributed generation, is an open
issue. Therefore, protection and post fault system control methods
should be fast, adaptive and intelligent, and should be supported by
effective and reliable communication systems.
The project aims to develop the communication technology based
intelligent methods of protection and post fault control for
distribution systems with large scale renewable energy generation
units and power electronic converters. The developed protection and
control methods will minimize the possibility of losing power supply
in an abnormal situation by stably operating a local system in an
island mode if the power system at a higher level fails and
restoring normal operation as quickly as possible. For this, we have
developed intelligent demand response management strategies to
stabilize the energy demand and production, considering renewable
energy resources, energy storage, and electric vehicles. We have
used M2M for the protection of distributed generation. Our developed
simulation platform evaluated overall system performance. The
results from the project are expected to be beneficial for
operators, consumers in LV residential areas and investors, as well
as equipment manufacturers.

We will also address the fundamental research issue in exploring M2M for the protection of distributed generation. The main objectives are to: 1) Study the characteristics of emerging distribution system with large number of renewable energy generation units. 2) Model the distributed generation systems. 3) Develop the intelligent and adaptive protection methods. 4) Establish control methods to stabilising the post-fault islanding system. 5) Determine cost effective communication system to support the protection and control methods. 6) Evaluate overall system performan ce.
