Research on configuration of vehicle-mounted mobile shore power system

Aimed at the problem of quantity configuration of the vehicle-mounted mobile shore power systems at the wharf, a multi-objective optimization model with the objective functions of minimizing the total cost of installing and using the vehicle-mounted mobile shore power systems and minimizing the tax paid on carbon dioxide and sulphur dioxide emissions is established, and the NSGA-Ⅱ algorithm is used to solve the model. The max-min standardization method and subjective weighting method are applied to derive the optimal decisions under different preference levels, and sensitivity analysis of two key parameters, government subsidy and emission tax rate, was carried out. The results show that the configuration of vehicle-mounted mobile shore power systems can enable wharves to achieve better emission reduction in the case of non-full-coverage construction of shore power systems, in the example, the configuration of three, two and one vehicle-mounted mobile shore power systems can achieve emission reductions of 100 percent, 87.5 percent and 49.4 percent, respectively. Changes in government subsidies have a greater impact on vehicle-mounted mobile shore power system configuration options, with increased government subsidies leading decision makers to favour higher configuration quantity options. The study has important reference value for promoting the popularization and application of port shore power system, energy saving and emission reduction.
