An overlapping of electrical and intelligence\\telecommunications infrastructures… the energy internet . In thinking of the power delivery system of the future, we found it helpful to think of bringing together two distinctly different but highly inter-related infrastructures. The electrical infrastructure (i.e., the poles, towers and wires) that has been created over the last 100 years and the “intelligence” infrastructure (i.e., the communications networks, distributed computing and sensors). The Intelligence infrastructure enhances the operation and maintenance of the electrical infrastructure and adds new functionality to the electrical infrastructure. The electrical infrastructure is very mature (at least in North America and Europe) – that is the processes, tools, standards and fundamental technologies for the electrical infrastructure are well established. New technologies will enhance the electrical infrastructure – and many programs within EPRI are working to develop that technology. The “intelligence infrastructure” is much newer – and companies thinking of this as a tightly integrated (networked) infrastructure is very new. The methods, tools and standards for creating the intelligence infrastructure are only beginning to be created. Essentially, when it comes to the intelligence infrastructure, it’s the wild west – almost completely lawless. In looking at the intelligence infrastructure – we see that it isn’t limited by technology. There is an abundance of technology that has been developed by other industries. Many times, in fact, there is too much technology. Today, pieces of the intelligence are installed in an isolated, fragmented way. this approach will not create an intelligence Infrastructure For the vision of the vision of the power delivery system of the future to be achieved, the intelligence infrastructure needs to be as pervasive and integrated as the electrical infrastructure – incorporating generation, transmission, distribution, energy markets and the consumer. The integration of these two infrastructures is what we see creating the intelligent grid or IntelliGrid.
Agenda: Introduction Today’s electrical grid Why do we need the smart grid? Smart grid applications Smart meter Electric vehicles Smart grid partners Conclusion
Today’s Electrical Grid Blackouts One way communication Energy by non- renewable resources Green House Effect
What does the concept of SmartGrid look like? Electrical Infrastructure “Intelligence” Infrastructure
Building Blocks HARD INFRASTRUCTURE – Smart meters – Transmission and distribution enhancements – Distributed energy storage – Household appliances communication SOFT INFASTRUCTURE – Standards for communication – Customer education – Customer behavioral adjustments
Smart Grid Enables….. Demand response Facilitation of distributed generation Facilitation of electric vehicles Optimization of asset use Problem detection and mitigation
Smart House Smart meter Thermostat Electric vehicle Roof top solar plant Wind mill
Smart Meter Enables….. Enables two way communication Wireless or mesh network or both Records electrical energy at intervals of time Customer energy management and demand response Smart charging of plug-in electric vehicles Integration of distributed generation resources Utility operational advantages such as outage detection and management, remote meter reading, and remote customer connections
Properties Of EV’s Levels of charging – Level 1- 120 V AC; 16 A (1.92 kW) – Level 2- 208-240 V AC;12 A - 80 A (= 2.5 - 19.2 kW) – Level 3- very high voltages (300-600 V DC); very high currents (hundreds of Amperes) Delivering energy back to grid Peak load leveling
Conclusion As we have seen, the smart grid is facilitating significant changes to the process of producing, transmitting and consuming electricity. Technological building blocks are allowing for new grid capabilities that, in turn, better support the utility mandate that increasingly includes certain societal benefits such as environmental performance and customer control. Early adopters have faced hurdles, but clear lessons have emerged that will assist all stakeholders as they carryout their respective roles.
