Abstract

The invention relates to the technical field of port shore power, and particularly relates to a port energy storage type shore power system which comprises an alternating current bus, a shore power bidirectional converter, a direct current bus, a shore power socket box, an energy storage system and an energy management system (EMS), whereinthe shore power bidirectional converter comprises a rectifier module and an inverter module, and the input end of the rectifier module is connected with the alternating current bus through the first transformer; the direct current bus is connected with the output end of the rectifier module, and the input end of the inverter module is connected with the direct current bus; the shore power socket box is connected with the output end of the inverter module through the second transformer; the energy storage system is connected with the direct current bus; and the EMS management system is connected with each of the energy storage system, the rectifier module and the inverter module. The energy storage system and the shore power share the input unit, the output unit, the bus and the control unit, the investment of the energy storage system can be remarkably reduced, the utilization rate of the energy storage system is improved, and then the shore power system can reduce the electricity price through the peak-valley electricity price difference to solve the problem that the utilization rate of shore power facilities is low.

Description

technical field [0001] The invention relates to the technical field of port shore power, in particular to a port energy storage type shore power system. Background technique [0002] In today's world, the trade between countries is very frequent, and the maritime transportation with ships as the main body has become the most important means of transportation for maritime trade among countries in the world. But at the same time, sea transportation has also generated serious environmental pollution problems. As governments and people all over the world are calling for protection and improvement of the environment, more and more attention has been paid to solving the pollution problem during the ship's berthing. It is becoming more and more important to seek specific and effective solutions to ensure the normal operation of ships while they are berthed in port, and to reduce the huge pollution generated by ships’ power generation. Under this background, ship shore power techno...
