Thermal Energy Storage (TES) - large scale
Attribute |
Unit |
Data type |
Description |
deployment |
– |
bool |
If set to ‘true’, the technology will be considered in the energy system model (this does not necessarily mean it will be used). Only relevant for optimisation. |
force_asynchronous_prod_con |
– |
bool |
If set to ‘true’, the tes cannot be charged and discharged simultaneously |
eta_chg_dchg |
– |
float |
Charging and discharging efficiency (fixed). Roundtrip-efficiency is calculated as eta_chg_dchg*eta_chg_dchg. |
tes_gamma |
1/timestep |
float |
Loss rate: fraction of heat lost to the environment during one timestep (e.g. 1 hour) |
capacity_kWh |
kWh |
float |
Storage capacity. |
force_cap_max |
bool |
||
chg_dchg_per_cap_max |
1/timestep |
float |
Max. charge/discharge (kW) per storage cap (kWh) per timestep. |
initial_charge |
– |
float |
Initial charge of battery (fraction of total storage capacity) |
optimized_initial_charge |
bool |
||
