Industrial energy balance management optimization software

Balancing time-varying energy consumption with supply resources allows to minimize the total energy cost or to maximize the total profit of the operation over a specified time range.

Based on the predicted energy consumption schedules, the Energy Optimization module of the ABB Energy Manager software can:

  • calculate the optimum use of supply resources to meet the predicted consumption at minimum total cost
  • optimize running schedules for selected consumers based on minimum energy cost and given restrictions
  • utilize a real-time LP / MILP optimization environment and economic flow network, in which the energy process is divided into logical sub-processes which are connected to each other through a flow network
  • optimize the complete energy flow network in real-time when any of the input parameters change, allowing the facility operators and management to maintain the most cost-effective operating mode in changing production conditions.

In the balancing process, the schedules are calculated and agreed daily for the next day. In strategic planning and budgeting, the schedules may extend over several months, or even years, while during real-time monitoring they may cover only the next few minutes or hours.

For a corporate customer multiple facilities can be integrated to provide a company-wide solution and to allow comparisons, benchmarking and sharing best practices between the production facilities.

Energy Manager balances time-varying energy consumption with supply resources. Your energy system is modeled as an Economic Flow Network. The Economic Flow Network considers the transfer and conversion of utilities such as fuel to steam, steam to electric power, fuel to CO2, etc. Depending on your objectives, energy resources are scheduled / dispatched to minimize the total energy cost or to maximize the total profit of the operation over a specified time range.

This configurable model is populated with data such as prices, volumes, validity times and other relevant information. The data may be either manual entered or acquired automatically, where available.

Benefits:

  • Employ optimal power resources
  • Lower power price by sending load schedules to power supplier
  • Avoid expensive power by demand scheduling
  • Lower balancing power and cost
  • Lower demand charges and penalty fees
  • Higher energy efficiency and reduced carbon footprint

Energy Manager can be used during the real-time operating phase to monitor the execution of power schedules. With real-time monitoring, deviations or unexpected events are detected and reported to help you minimize their costs.

The load planning module automatically recalculates the load schedule based on changes in process measurements, production plans or user inputs. If an imbalance between predicted power consumption and planned supply is detected, the deviation from plan may be balanced through additional power trading.

The Tie-Line Power Monitoring module predicts total utility consumption within the current billing period by integrating and extrapolating the flow in the tie-line. If the predicted volume exceeds pre-set or calculated alarm limits, alarms can be generated enabling the operator to take action to limit the deviation.
