RESEARCH ON CHARGING AND DISCHARGING STRATEGY OF ELECTRIC VEHICLES IN PARK MICRO-GRID BASED ON PIGEON-INSPIRED OPTIMIZATION ALGORITHM

To reduce the adverse impact of electric vehicles on the power grid, compensate for instabilities caused by randomness of the distributed energy, reduce user cost, and improve user satisfaction, an optimisation strategy is proposed herein for orderly charging and discharging of electric vehicles. The daily load rate of the park micro-grid, peak-valley difference of the load, and economic benefits to the users are considered as the optimisation objectives, and the uncertainty of solar power generation and energy storage are considered fully. The strategy for pigeonholing optimisation based on quantum behaviour is proposed to organise the charging and discharging behaviours of electric vehicles reasonably while realising benign interactions between the electric vehicles and grid; the feasibility and superiority of the proposed strategy are also verified by simulation experiments.
