A Planning Model and Method for an Integrated Port Energy System Considering Shore Power Load Flexibility

doi:10.16183/j.cnki.jsjtu.2021.293

Abstract

Abstract:

An integrated port energy system planning model is established considering the flexibility of shore power load to finely model the shore power load. Next, the proposed model is decoupled into shore power load elasticity and integrated energy system planning. Then, the shore power load curve of the port-ship master-slave game model is calculated. Finally, the optimal response method is used to iteratively solve the optimal integrated energy system planning method considering the shore power load elasticity. The simulation results show that the model can help rationally allocate resources in the port area, effectively improve the energy efficiency of the port area, increase the revenue of port area, and help the port area to save energy and reduce emissions.

Key words: shore power, load flexibility, energy conservation and emission reduction, integrated energy system planning, best response algorithm
