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.
