The rapid popularity of electric vehicles and charging piles has brought convenience and at the same time their charging and discharging behaviour has caused a huge impact on the safety and stability of the power grid, so orderly charging technology has come into being. At the present stage, the charging pile orderly charging function lacks effective detection means, and it is impossible to judge whether the orderly charging strategy is implemented or not, and the effect of the strategy implementation cannot be evaluated. Therefore, a large-scale charging pile orderly charging strategy detection system of on-site charging pile + energy controller + detection equipment + cloud platform is proposed. First, the hardware structure and communication method of the detection equipment and are designed. Then, a multi-scene and multi-timescale electricity demand simulation model is established, and the detection software based on the cloud platform is designed. Finally, an orderly charging strategy evaluation model is constructed to realize the orderly charging strategy detection and evaluation of scale charging piles.
