Developing models for smart grids: Which way to go? Prof. Dr. ng. Johanna Myrzik, TU Dortmund, Germany
Content Definition of a smart grid Goals Consequences Tools Which way to go?
Smart grid definition A smart grid facilitates generation and distributes electricity more effectively, economically, securely, and in a sustainable way. t integrates innovative technologies, products and services, from generation, transmission and distribution all the way to and from consumer appliances and equipment using advanced sensing, communication, and control technologies.

Some challenges Consumer interaction and intelligent appliances End-user real time information and participation Seamless integration of new appliances Central & dispersed ntelligence Agent devices Smart (power) electronics DC/AC integration ntegration macro & micro Generation ntegration constant & intermittent dec 2008 PAGE 4
Goals ntegration central/dispersed, continuous/intermittent, non sustainable/sustainable sources ntegration end user participation ntegration old with new ntegration of co generation New facilities in old networks
Consequences for nfrastructures The E network may be sufficient but the functions change Profiles totally different through E cars application Bidirectional power flow Controllable generation units Automation and power flow control
Consequences for nfrastructures District heating and cooling infrastructure Energy management system and communication Metering systems and load response Thermal and electrical storage
Tools Smart network concepts Autonomous operating networks, micro grids Virtual power plants ntelligent CT network concepts
Autonomous controlled networks MV DC Link to next network = = = MV DC Link = MV DC Link to next network
Macro and Micro grids Transmission network Off shore wind energy Conventional power plant Energy storage Heavy industrial load Distribution network (Biomass) CHP Solar energy Small wind energy Energy storage Fuel cells Small industrial load Urbane load Local load

Tools Soft skills Operational modeling & forecasting Ancillary services Economical and political strategies
Which way to go? The way will be full of diversities No monolith structure The model of the smart grid have to join the environmental requirements, the application requirements and end user We have to start consequently with (more) demonstration/pilot projects and prototypes
