Optimal Charging Policy for Electric Vehicles under Net Energy Metering with Renewable Generation and Flexible Loads

A procrastination threshold policy that delays EV charging to the last possible moment is optimal when EV charging is co-optimized with flexible demand, and the policy thresholds can be computed easily offline. The net consumption of the prosumer is a two-threshold piecewise linear function of the behind-the-meter renewable generation under the optimal policy.
