ABSTRACT
Deregulation and privatization are posing new challenges on high voltage transmission and on
distributions systems as well. System elements are loaded up to their thermal limits, and power trading
with fast varying load patterns is contributing to an increasing congestion. In addition to this, the
dramatic global climate developments demand for changes in the way electricity is supplied.
Environmental sustainability and security of power supply are the goals for future grid developments.
Estimated global investments required in the energy sector until 2030 are $16 trillion, according to
IEA statistics. In Europe alone, some € 500 billion worth of investment will be needed to upgrade the
electricity transmission and distribution infrastructure [1]. The work of the future must
be secure, cost-effective and patible.
KEY WORDS:
Security and Environmental Sustainability of Supply; Smart Grid Technologies; Elimination of
Bottlenecks in Transmission; Blackout Prevention; Increase in Transmission Capacity; Reduction in
Transmission Losses; Enhanced Grid Access for Regenerative Energy Sources (RES)
1. INTRODUCTION
The vision and enhancement strategy for the future works is depicted in the program for
“SmartGrids”, which was developed within the European Technology Platform (ETP) of the EU in its
preparation of 7th Frame Work Program.

Features of a future “SmartGrid” such as this can be outlined as follows [1]:
• Flexible: fulfilling customers’ needs whilst responding to the changes and challenges ahead
• Accessible: granting connection access to work users, particularly for RES and high
efficiency local generation wit
