基于泊位与岸桥调度的港口微电网优化运行方法研究OA

The high energy consumption and pollution characteristics of the shipping industry are becoming more and more prominent with the increase of trade volume.Consequently,the development of electrification has become a necessary pathway for the green transformation of the shipping sector.We propose a joint day-ahead scheduling method to jointly optimize the operation strategy of the port logistics system and the energy system through the cooperative functioning of the shore power system and the port microgrid.The method establishes a coupled logistics-energy model for the port power grid,comprehensively considering factors such as the ship berthing time,shore bridge operation sequence,shore power demand curve and microgrid dynamic tariffs.It also considers the uncertainty of the port living load forecast and renewable energy output.Furthermore,the study investigates the flexible synergistic mechanisms of multiple shore bridges,and proposes a scheduling strategy that integrates load leveling with time-of-use tariff differentials.This approach aims to reduce energy costs and alleviate pressure on the microgrid.Examples show that the proposed joint scheduling algorithm can enhance the energy independence,port operation efficiency,reliability,and economic performance of port microgrids compared with the traditional berth allocation strategy.
