Active power compensation by Smart Park in DC metro railways

Smart Park associated shunt active filter has the potential to support the main grid with respect to harmonic, reactive and active power needed by the load. By incorporating modified Icos φ controller, active power support capability of Smart Park is studied in accordance with the SOC of master battery and the source current as constraints. The results of simulation prove the effectiveness of active power compensation capability of Smart Park together with harmonic and reactive power compensation for a 750V DC metro traction system.
