Integrated Resource Scheduling Scheme For Seaport Considering Berth Allocation And Multi-Energy Coordination

As a bridge to connect the land and sea,the seaport is an important hub of trade and transportation,and the emissions within a seaport have caused tremendous pressure on urban environmental protection.On-shore power could replace diesel-consuming auxiliary engines to supply energy to vessels during berthing in ports,and is viewed as one of the important solutions to reduce gas emissions in the seaport area.Conventionally,there is only logistic connection between seaport and berthing vessels,such as berth allocation,which allocates berths to the calling vessels.With the promotion of cold-ironing technology,the seaport will become a multi-energy transportation system in the future,and the energy management scheme of seaport determines its environmental and economic characteristics.There are many different types of vessels arriving at seaport,such as cruise vessels and reefer vessels.which have electrical loads and a large amount of heating and cooling loads.When the seaport supplies energy to these types of vessels based on on-shore power,there is a joint scheduling of multi-energy resources and transportation.Therefore.this paper studied the optimization of seaport integrated energy system operation considering berth allocation and multi-energy coordination.The main research works are as follows.Firstly,a multi-energy framework for seaport integrated energy system is proposed.The characteristics and mathematical models of the energy supply units are studied.Based on cold-ironing technology,the actual constraints of seaport berth allocation are illustrated.and the berth allocation logistics model is established.Secondly,from the perspective of seaport operators,an integrated energy system optimization model for seaport is established,which is based on the combined cooling,heating and power system.The seaport supplies energy for berthing vessels.Through optimizing the multi-energy supply decision of seaport,the cost of seaport operation could be minimized.The model is constructed as a mixed-integer linear programming problem,and the effectiveness of the model in reducing energy supply costs is verified by solving an example.Finally,an integrated resource scheduling scheme under the background of full electrification is proposed to optimize the operation cost of the seaport multi-energy system while taking the berth allocation and cold-ironing technology into consideration.The results of case study verify the effect of optimal berth allocation in reducing costs.The seaport schedules vessels with electricity,heating,and cooling loads based on time-varying energy costs to achieve demand response,and makes optimal energy supply decisions.This paper integrates dynamic electricity prices with seaport plan for sensitivity analysis.The advantages of combination of the two in reducing seaport energy supply costs are verified.
