Study on charging strategy of electric vehicle parking lot based on improved PSO

Electric vehicle parking lot is a kind of profit service facilities nearby commercial office buildings for electric vehicles to park and charge. A V2P model is built to describe electric vehicles charging in the parking lot based on V2G (vehicle to grid) technology. Under the conditions of real-time pricing, improved particle swarm optimization (PSO) algorithm is applied to study on charging strategies of electric vehicles. 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.
