INCREASED WIND ENERGY EXPLOITATION VIA INTERCONNECTION OF AEGEAN ISLANDS TO THE MAINLAND GRID

National Technical University of Athens (NTUA), Greece
04/2007;

ABSTRACT In this paper the interconnection of Aegean Sea islands to the mainland grid of Greece is evaluated, as an alternative to their current autonomous operation, fed by local oil-fired power stations. Interconnection of the islands increases substantially the potential for exploitation of their favourable wind resources. The paper presents results of a preliminary feasibility analysis, which evaluates alternative interconnection technologies and calculates the fundamental economics of each solution over a 25-year evaluation period.

    • "Taking into account the former feasibility studies presented in [1] and [2], this paper presents technologies that can be applied for the reliable and cost-effective interconnection of the Aegean Islands and OWPPs to the Greek mainland grid. In Section II, the current status in HVAC and HVDC technology is presented, including the alternative configurations of the state-of-the-art interconnection schemes. "

    ABSTRACT: The main objective of this paper is to provide an overview of the state-of-the-art transmission technologies for the interconnection of remote island networks and offshore wind power plants (OWPPs), applicable to the interconnection planning for the Aegean Sea, Greece. Alternative transmission options are presented, describing the advantages and drawbacks of each technology, namely High Voltage AC (HVAC), and High Voltage DC (HVDC). Important developments in HVDC transmission based on Voltage Source Converters (VSC-HVDC) are also highlighted, along with essential grid code (GC) requirements applicable to offshore generating units. Last, important technical considerations requiring further research are also pointed out and discussed.

    ABSTRACT: Crete is the largest autonomous power system in Greece with significant RES penetration and expensive oil-fired units. There are concrete plans for interconnecting Crete with the Hellenic Transmission System via High Voltage Direct Current (HVDC) submarine cables. Interconnection plans of Crete with Cyprus and Israel also have been announced. These interconnection plans will inevitably change the operation of the Cretan power system. This paper, additional to technical details presents the major concerns from the operator's perspective for the protection schemes required.
