The automatic Production and Accumulator Optimization module from 7-Technologies minimizes the operational cost of the district heating network. The best possible production scenario is chosen to ensure minimum production cost. The Production and Accumulation Optimization module encompasses the heat volume supplied to the consumers in the network while also using the flexibility and dynamics provided by the accumulator tank.
It also provides for the accumulated heat loss and energy consumption in the network, the hydraulic constraints as defined in TERMIS Operation and the forecasted load as a result of predicted outdoor temperature and wind speed conditions.
Operational Cost Savings
automatic Production and Accumulator Optimization reduces your energy
costs with approximately 5-10% depending on the flexibility and
variation in fuels. This will not only improve your economy, but also
reduce the CO2 emission.
The use of the
Production and Accumulator Optimization will see fewer boiler start-ups.
As a result of this the maintenance will be reduced leading to an
extension of the life span of these units.
The system can be
completely embedded in your SCADA system and be provided by your usual
supplier. This allows for an uninterrupted supplier support and you can
work with the supplier you usually do business with.
The module requires
limited or no intervention. The module is in operation around the clock.
Save money all the time – every single day of the year.
Production and Accumulator Optimization
The Production and Accumulator Optimization module uses SCADA data from the district
heating network, creating the best possible basis for the optimization.
The module allows for common operational
changes and adjustments such as valves being opened or closed, consumers with varying consumption, and variation in load during weekends and
interruptions, such as boilers being out of operation, will also be
included in the calculation to provide the best status possible for the
operation at all time.
Production and Accumulator Optimization continuously performs a load
prediction for example based on a weather forecast downloaded from the
Based on the input stated in
the preceding and knowledge of the network capacity, defined
constraints, etc., the Production and Accumulator Optimization module
provides the Operator with a schedule for the operation of the plants.
Based on a production cycle of 24 hours, the schedule defines which
plants to be used and which boilers. The outcome of such a schedule is a
reduction of the production cost and an operation scenario for the
Production Scheduler is required in case of three or more plants.
existing TERMIS model can be utilized directly. If you are using an
alternative modeling tool, this model can be directly and easily
transformed into TERMIS.
Implementation of the Production and Accumulator Optimization module
requires no knowledge about the operation of TERMIS.
The TERMIS Operation
Real-Time functionality can be used to display full and dynamic results
for temperature, pressure and flow. This will provide you not only with
the perfect overview but also with a lot of information about the
operation of your network.
Send calculated data into the SCADA system.
This will provide a better overview and possibly postpone or eliminate
the need for adding new and costly measurement points.
TERMIS Operation is today the most widely used simulation tool for
district energy networks.
