Dynamic optimization of charging strategies for EV parking lot under real-time pricing

Electric vehicle parking lot is a kind of profit service facilities nearby commercial office buildings for electric vehicles to park and charge. A V2P(vehicle to parking lot) model is built to describe electric vehicles charging in the parking lot based on V2G (vehicle to grid) technology. Under the conditions of the real-time pricing, dynamic optimization model is proposed based on the V2P model. Improved particle swarm optimization (PSO) algorithm is applied to study on the dynamic optimization of charging strategies for EV parking lot. Real-time electrovalency data of PJM and the parameters of mainstream electric vehicles are used in simulation. Results of the simulations show that the proposed model is reasonable and the improved PSO algorithm is both efficient and effective.
