The document discusses the smart grid, which aims to address issues with today's electrical grid such as blackouts and one-way communication. It introduces the concept of adding "intelligence infrastructure" like smart meters, transmission upgrades, energy storage, and networked appliances. This smart infrastructure enables features like demand response, distributed generation, electric vehicles, optimized asset use, and problem detection. Key components are discussed in more detail, including smart meters, electric vehicles, and potential partners for building smart grid cities. The conclusion outlines how the smart grid facilitates changes to electricity production, transmission and consumption while supporting environmental and customer control goals.

17. 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
19. 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.
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.
