Optimal Operation of Co-phase Traction Power System with Hybrid Energy Storage and PV Integrated

A methodology of energy management for the co-phase traction power system with hybrid energy storage system (HESS) and photovoltaic (PV) panels integrated is proposed in this study. This energy management problem is developed as a mixed-integer linear programming (MILP) model with the target of lower operating costs, and the constraints of three-phase voltage unbalance are taken into account in particular. Several linearization approaches are applied for the formulation of MILP model and the scenario-based technique is also adopted for the uncertainty of PV generation. A real case analysis is conducted to validate the feasibility of proposed approach.
