1. Optimization of EV Charging Shivam Patel Final Presentation 07/23/15 CURENT

2. Purpose EV sales on the rise Maximize profits for charging companies Optimize power flow 5-2

3. EV Charging Level1-slow charging(2-5 miles of range per hour charge) Level2-10-20 miles of range per hour charge DC Fast Charge-50-70 miles of range per 20min 5-3

4. Problem Formulation 5-4 Profit-Cost Battery Power Constraint Power Outflow Constraint Power in = Power out Power sold to grid greater than 0 Power purchased from grid greater than 0 SOC after 24hr is 50 percent

5. Power Curve Generation 5-5 Parking lot occupancy EV charging levels State of Charge

6. Charging Curve Average Power Demanded Indexed at 9pm Power distributed to charging vehicles 5-6

7. Results Represents net power to grid and outflow power from battery 5-7

8. Conclusion Optimum power flow under given circumstances Methods and results can be referred to for maximizing profits 5-8
