  • opt_horizon (list of integers) – Time step identifiers in the optimization horizon.

  • ecap (float) – Energy capacity of battery (kWs).

  • v2gall (float) – V2G allowance discharge (kWs).

  • tarsoc (float) – Target final soc (0<inisoc<1).

  • minsoc (float) – Minimum soc.

  • maxsoc (float) – Maximum soc.

  • crtsoc (float) – Target soc at crttime.

  • crttime (int) – Critical time s.t. s(srttime)> crtsoc.

  • arrtime (dict of int) – Cluster differentiating arrival times.

  • deptime (dict of int) – Cluster differentiating departure times.

  • arrsoc (dict of float) – Cluster differentiating arrival soc in [0,1).

  • p_ch (dict of float) – Nominal charging power (kW).

  • p_ds (dict of float) – Nominal charging power (kW).

  • g2v_dps (dict of dict) – G2V dynamic price signals of clusters (Eur/kWh).

  • v2g_dps (dict of dict) – V2G dynamic price signals of clusters (Eur/kWh).

Returns:
