摘要: Energy Storage Systems (ESSs) represent one of the main vectors for improving railway electrical systems. Former low reliability rates and life-time are being dramatically improved in recent times due to intensive research on battery capacitor technologies. However, little has been conducted optimization system infrastructure by incorporating ESSs. This paper presents a method designing best possible deployment ESSs DCelectrified mass rapid transport line means optimization, selecting number location A detailed model load flow energy storage devices given traffic scenario general DC carried out, resulting MINLP optimisation that minimises total consumption. Then, linearization equations performed order get fast-approximate solution converting problem into MIP one. applied realistic system, yielding reasonable system. The error approximation evaluated comparing results linear against those non-linear flow. demonstrated be powerful tool decide how many where place DC-electrified
