With the introduction of the dual-carbon goal, the role of transportation electrification in carbon reduction has been paid more and more attention, and the electrification of ports and ships is also an indispensable part of it. However, the current Vessel-Grid-interaction (VGI) operation model is still unclear. This article proposes a method of power grid interaction value analysis for ship-based charging stations in response to this situation, in order to provide a path for future research of V2G (Vessel-To-Grid). From the perspective of the value of the whole society, this article comprehensively analyzes the economic effects of vessels charging stations participating in multiple grid interactive services. The limit method and the curve method are respectively proposed to evaluate the elasticity of ships. Comprehensive consideration of orderly charging (represented by V1G) and V2G scenarios brings many benefits, such as reducing peak power plant investment, improving local distribution network power supply capacity, improving distribution network line reliability, reducing power outage losses, and absorbing local new energy. The results show that the scale effect in the VGI scenario does not become more and more obvious with the increase in the number of vessels. On the one hand, the demand on the grid side will reach saturation at a certain point, and on the other hand, the investment and operation and maintenance costs will also be greater. We can stimulate more vessels to participate in VGI through some means, but at a certain point, the optimal balance point will be reached, and then more stimulation will be very uneconomical;
