Add Storage Technology Candidates
The workflow for adding storage technology candidates to your analysis is identical to that for adding conversion technology candidates, except that the fields specifying the properties of the technology are different.
Explanation of storage technology parameters:
PARAMETER | UNITS | REQUIRED? | DEFAULT | EXPLANATION |
General parameters |
|
|
|
|
Technology name |
| Yes |
| The name of the technology; can be selected freely |
|
|
|
|
|
Optimization options |
|
|
| These options are mutually exclusive (only one can be selected) |
This technology can be installed in these Hubs |
|
| TRUE, All hubs | The hubs in which the technology is allowed to be installed |
This technology must be installed in these Hubs |
|
| FALSE | The hubs in which the technology is forced to be installed |
This technology must Be Installed in At Least One Hub |
|
| FALSE | In this case, the optimizer will force the installation of the technology in at least one hub. This option can be used if you would like to force the installation of the technology, but you want to know in which hub the technology should optimally be in installed. |
Storage parameters |
|
|
|
|
Stored Energy Carrier |
| Yes |
| The energy carrier that is stored in the technology |
Technology capacity | Optimize / Specify Capacity |
| Optimize | Select whether to Optimize the capacity or specify the capacity manually (Specify Capacity) |
Capacity | kWh | Yes, if "Specify Capacity" is selected above |
| The pre-specified capacity of the technology; only visible if Specify Capacity is selected above. A non-zero value of this parameter does not force the installation of the technology. Rather, it only specifies that, if the technology is installed, this is the capacity which it must assume. |
Maximum capacity | kWh |
| Infinity | The maximum allowable capacity of the technology; only visible if Optimize is selected for "Technology capacity" |
Minimum capacity | kWh |
| 0 | The minimum allowable capacity of the technology; only visible if Optimize is selected for "Technology capacity" |
Standby Loss (%/hour) | % /hour |
| Infinity | the losses of the storage technology as % of total capacity per hour. E.g. a Standby Loss of 0.01% for a storage technology with 100kWh of optimized capacity means 0.01kWh of losses per hour |
Minimum SoC [%] | % |
| 0 | The minimum State of Charge (SoC) as % of total optimized capacity of the storage technology |
Dis/Charging parameters |
|
|
|
|
Storage Charging Efficiency | % | Yes | 100 | Energy efficiency of the process of charging the energy in the storage technology |
Storage Discharging Efficiency | % | Yes | 100 | Energy efficiency of the process of discharging the energy from the storage technology |
Maximum Charging Rate | %/hour | Yes | 100 | The maximum rate of charging of the storage capacity as % of the total capacity per hour. (E.g. a discharging rate of 1% per hour for a optimized capacity of 100kWh means 1kWh of max discharging rate per hour) |
Maximum Discharging Rate | %/hour | Yes | 100 | The maximum rate of discharging of the storage capacity as % of the total capacity per hour. (E.g. a discharging rate of 1% per hour for a optimized capacity of 100kWh means 1kWh of max discharging rate per hour) |
Cost parameters |
|
|
|
|
Lifetime | years | Yes |
| The financial lifetime of the technology; specified in years. This is used as a basis for annualizing the investment costs of the technology. |
Fixed Investment cost | CHF |
| 0 | The fixed investment costs of the technology (not annualized), incurred in the specified amount if the technology is installed, regardless of the sizing. |
Variable Investment Cost | CHF/kWh |
| 0 | The variable investment costs of the technology (per kWh of installed capacity, not annualized) |
Fixed O&M Cost | CHF/year or |
| 0 | The operation and maintenance costs of the technology that are incurred as a fixed amount each year if the technology is installed |
Variable O&M Cost | CHF/kWh/year |
| 0 | The operation and maintenance costs of the technology (per kWh of installed capacity) that are incurred as variable amount each year depending on the installed capacity. |
Environmental parameters |
|
|
|
|
Fixed Embodied CO2 | kg-CO2 |
| 0 | The embodied CO2 of the technology (i.e. the CO2 emissions incurred in the course of the technology's production and installation) |
Variable Embodied CO2 | kg-CO2/kWh |
| 0 | The embodied CO2 of the technology (i.e. the CO2 emissions incurred in the course of the technology's production and installation); expressed per kW of installed capacity |
