1 Pathway to smart grid - Evolution steps of today's grid to become ready for the future Dr. Rolf Apel Principal Smart Grid, Siemens AG, Germany

2 Electrical energy the backbone of our society

3 Customers ideas of the Smart Grid Auto-balancing, self-monitoring power grid that accepts any source of fuel (coal, sun, wind) and transforms it into a consumer s end use (heat, light, warm water) with minimal human intervention. A system that will allow society to optimize the use of renewable energy sources and minimize our collective environmental footprint It is a grid that has the ability to sense when a part of its system is overloaded and reroute power to reduce that overload and prevent a potential outage situation. A grid that enables real-time communication between the consumer and the utility, allowing the consumer to optimize energy usage based on environmental and/or price preferences. Source Xcel Energy s

4 The starting point: changing needs, growing demands Increased energy trading Energy efficiency Greater network complexity and vulnerability Network conditions and requirements Cost pressure Fluctuating infeed Aging infrastructure and lack of experts Integration of renewable energy sources Increasing distance between generation and load Power quality Integration of distributed energy resources Integration of intelligent buildings High supply quality Legal and regulatory framework External influences CO 2 reduction Operational factors

5 The starting point: Drivers for flexible and (cost)-efficient grids Drivers Need for more energy Challenges for the utilities Efficient grid for profitability Regulatory and political push Environmental sustainability Competitive energy prices Security of supply Multiple infeed for flexibility Demand side management for accessibility Aging infrastructure and workforce Quality assurance for reliability

6 The solution: Smart Grid

7 What does Smart Grid really mean? From Congestion, bottlenecks, and blackouts Heterogenous communication networks varying in capacity and bandwidth Complex, personal intensive engineering and operating Primary equipment condition not well known and not overall integrated Central generation, decentralized consumption Manual and operating experience based reaction on critical situations Unmanaged, intransparent consumption Optimization of building life cycle efficiency as standalone process To Security, sustainability, and efficiency of power supply Homogeneous Smart Grid communication network with IP/ Ethernet connectivity between all components Smart substation automation Condition monitoring for better asset performance and grid asset management for advanced asset management Integration of distributed energy resources (DER) and storage by virtual power plants Smart, self-healing grid Smart metering and load management Active participation of buildings in the grid as consumer, producer, and energy storage facility Relevance Distribution Transmission

8 Consequence: Processes are merging and require integration Enterprise resource planning Business processes customer and market Grid operation Plant operation Power grid Information and Communication Technology Smart Grid Information and Communication Technology Generation Transmission Distribution Consumption

9 Siemens takes the lead in integrating Smart Grid solutions Reliability and efficiency planning Managed operational reliability Resource optimization Smart generation Smart Grid Smart consumption Transmission grid Distribution grid Planning and modeling back office / front office Wind power Distant solar power Distributed energy resources Decision support system integrity protection Power electronics Advanced Energy Mgmt. System (EMS) Substation automation and protection Asset management Condition monitoring Distribution Management Systems (DMS) Distribution automation and protection Meter Data Management (MDM) Smart meters / demand response Industrial and commercial loads Residential loads E-cars, batteries Common information models and communications protocols E-cars, batteries

10 Enabling interaction One-stop communication solutions for utilities and retailers include IP solutions SDH/PDH solutions Powerline carrier and teleprotection equipment Wireless solutions Optimized solutions for medium and low voltage applications Live line installation End to End Communication Network Solutions are the basis to build a Smart Grid for Power Utilities
