Increasing operation costs and carbon emissions have brought great challenges to the development of port systems, which are regarded as prosumers that comprise various renewable energy sources diversiform electric loads. In this paper, an transaction framework for green with a multiport power electronic transformer (PET) is established optimize system in day-ahead reserve markets. The market behavior formulated bi-level stochastic optimization model. source schedule, berth allocation, quay crane (QC) assignment optimized minimize total cost at upper level, whereas clearing problems settled lower level. aforementioned nonlinear problem solved mathematical program equilibrium constraints (MPECs). Karush–Kuhn–Tucker conditions duality theory convert proposed into linear single-level problem. Numerical simulations show strategy can achieve lowest port.
