1 How to Design a Communication Network over Distribution Networks Overview. Key issue: IP technology. Design rules. GAD Project. Experience. Conclusions. Acknowledgments.

2 Overview Increase of the energy demand. New energy resources located along wide areas. Need to update electrical networks: Smart Grids. Allow interaction between operators and customers. Improve power quality and grid security. Integrate Distributed Energy Resources. Provide self-healing mechanisms.

3 Overview Requirements for Smart Grids. Based on Open Standards. Must be interoperable. Allow communications between different operators. Easy network management: Plug and Play.

4 Key issue: IP technology IP technology supports different services over several network technologies.

5 Key issue: IP technology IPv6 features: Scalability of network more network addresses. Quality of Service management: traffic classes and flow labels. Security mechanism IPSec. Use of Plug and Play devices.

6 Key issue: IP technology Several service protocols and network technologies only have an IPv4 convergence layer. Mixed network: Rapid deployment. Small number of boundaries. Plan the transition to IPv6 network.

7 Design rules Specify the communication requirements and QoS. Mandatory requirements for the service in study. Optional requirements for the future Smart Grids. Analyze the communication technologies used by the DNO. Reuse the technologies deployed over DN.

8 Design rules Select network technologies for segments without communication infrastructure. Newest technologies are recommended. Plan the communication system over the electrical grid scalable network. Addresses assignment. Network components.

9 GAD Project Active Demand Side Management by means of Intelligent Devices allowing the lamination of demand curve, and the reduction in the demand growth. Sponsored by the CDTI (Technological Development Center of the Ministry of Industry, Tourism and Commerce of Spain).

10 Structure. GAD Project 1. Scenario analysis. 2. Tariffs and regulation. 3. Algorithms. 4. Load measurement and management. 5. Communication. 6. Testing and validation. 7. Results Analysis.

11 Experience GAD network proposal: from DNO to Costumer.

12 Experience GAD network proposal: at Customer s home.

13 Conclusions Need of new services to manage: Electrical grids. Distributed Energy Resources. Demand response. Others. Deployment of new services thinking in Smart Grids.

14 Conclusions One common communication system: Supports different services. Based on open standards interoperability. Reliable and secure technology. Solution: IPv6 technology. Problem: not all protocols are defined to be used with IPv6 technology. Mixed networks.
