Panel Session 1Smart Grid: Development and
implementation
Prof. Nikos Hatziargyriou,National Technical University of Athens
In transition
SEEEI, Dan Eilat Hotel, Israel, November 14-17, 2012
Transition: driving factors• Increased customer participation• European and national policies encourage lower
carbon generation, RES and efficient energy use• Integration of RES and DG into the grids• Need for investment in end-of-life grid renewal
(ageing assets)• Handle grid congestion (with market based methods)• Reduce uncertainty for investment• Progress in technology
SEEEI, Dan Eilat Hotel, Israel, November 14-17, 2012
Smartgrid essential components• Customers are part of the “network-loop”, both
producer and consumer = “prosumer”– Real-time price information (smart meters)– Automated systems + convenience (DR/DSM)– Adequate investment and reward incentives
• Integration of millions small scale generators• Bulk power and small scale sustainability coexistence • Demand and supply balance solutions• Efficiently operated (and reliable) network • Mature markets and regulation

Smartgrids technical, economic and environmental benefits
• Energy efficiency • Minimisation of the overall energy consumption • Improved environmental impact • Improvement of energy system reliability and
resilience • Network benefits (lower losses, congestion reliefs,
black start, ancillary services)• Cost efficient electricity infrastructure replacement

Microgrids - Integration of SG components
Microgrids are electri-city distribution systems containing loads and distributed energyresources, (such as distributed generators, storage devices, or controllable loads) that can be operated in a controlled, coordinated way, either while connected to the main power network and/or while islanded.

Microgrids – Hierarchical Control
MicroGrid Central Controller (MGCC) promotes technical and economical operation, interface with loads and micro sources and DMS; provides set points or supervises LC and MC; MC and LC Controllers: interfaces to control interruptible loads and micro sources

Technical Challenges for Microgrids• Small size (challenging management)• Use of different generation technologies (prime
movers) • Presence of power electronic interfaces • Relatively large imbalances between load and
generation to be managed (significant load participation required, need for new technologies, review of the boundaries of microgrids)
• Specific network characteristics (strong interaction between active and reactive power, control and market implications)
• Protection and Safety / static switch• Communication requirements
Market and Regulatory Challenges• coordinated but decentralised energy trading and management • market mechanisms to ensure efficient, fair and secure supply and
demand balancing • development of islanded and interconnected price-based energy and
ancillary services arrangements for congestion management • secure and open access to the network and efficient allocation of
network costs • alternative ownership structures, energy service providers • new roles and responsibilities of supply company, distribution
company, and consumer/customer
