State Of Charge This incentive promotes more charging and higher values of
SOC. Both State Of Charge Penalty and State Of Charge
Incentive
($/kWh2) Incentive settings are provided to allow you more freedom to
configure the system based on your operational knowledge.
The cost is in dollars; for other currencies simply enter that
value and be consistent in all fields involving the currency.
State Of Charge The setting is the penalty when storage is allowed to violate its
minimum level (that is, soft constraint is set for Constraint
Minimum
Penalty Mode. The greater the violation from State Of Charge
($/kWh2) Minimum, the greater the penalty cost in the objective
function.
The cost is in dollars; for other currencies simply enter that
value and be consistent in all fields involving the currency.
Hysteresis The DMC490 MGC supports input up-time, down-time, and
cycle-per-day hysteresis. When Hysteresis is On, a set of
appropriate parameters is in place to prevent excessive
switching and cycling. Support for hysteresis is required for
storage input to overcome high-frequency on/off cycling of
the electrolyzer because it lowers performance and decreases
the life of the device. The hysteresis mostly targets the
electrolyzer (hydrogen-based storage), but it is available for all
storage devices.
Charging When the Hysteresis field is set to On, this is the minimum
Minimum Up running time of the electrolyzer, in minutes. If the electrolyzer
Time (minutes) is turned on, it runs for at least this length of time. When
storage input is offline and the optimal dispatch result
indicates storage input usage above the minimum storage
input (Minimum Charging Power) for equal to or longer than
the Charging Minimum Up Time, then the storage input is
started with the calculated setpoint.
Charging When the Hysteresis field is set to On, this is the minimum off
Minimum Down time of the electrolyzer, in minutes. When the electrolyzer is
Time (minutes) on and receives an off command, it turns off and stays off for
at least this length of time.
