To this end, this paper proposes a compensation mechanism for energy storage to participate in peak regulation and fre-quency regulation services on the premise of China''s electricity market environment.
The investment cost of charging stations is high and the equipment utilization rate is low, resulting in a waste of charging resources. The application of new charging piles, charging robots and other automatic charging devices with automatic charging functions is one of the solutions to improve the utilization rate of charging pile resources.
Currently, new energy vehicle charging piles are manual charging piles. Due to the fixed location of the charging piles and the limited length of the charging cables, manual charging piles can only provide charging services for the vehicles to be charged in the nearest two parking spaces at most.
If the number of charging piles is greatly increased, the power system will inevitably need to be expanded, which will be costly. The investment cost of charging stations is high and the equipment utilization rate is low, resulting in a waste of charging resources.
Volume 306, 15 October 2024, 132428 A “1 to N” automatic charging pile is designed and tested for the first time. The temporal and spatial utilization rate of charging devices is improved. The fairness in charging behavior is realized by a layered charging strategy. The impact of the charging demand uncertainty is investigated and restrained.
With the development of technology, the number of new energy vehicles continues to increase, and community residents have an increasingly strong demand for charging and energy replenishment. Public charging piles have become the most lacking “new community infrastructure” in the community.
The advantage of DC charging pile is that the charging voltage and current can be adjusted in real time, and the charging time can be significantly shortened when the charging current are large, which is a more widely used charging method at present.
To this end, this paper proposes a compensation mechanism for energy storage to participate in peak regulation and fre-quency regulation services on the premise of China''s electricity market environment.
