Optimization Method of Seaport Cascade Logistics-Energy System

This paper proposes a coordinated optimization method for seaport systems to reduce operating costs and improve energy efficiency. Firstly, a coupling model is used to quantify the dynamic power correlations among yard cranes, electric trucks, and charging loads. Secondly, a coordinated optimization model is established for the seaport cascaded logistics-energy system. Thirdly, the proposed model is linearized by using the Big-M-based auxiliary variables, moreover an improved NSGA-II algorithm is proposed for solving. Simulations using a 24-hour port scheduling cycle demonstrate the effectiveness.
