1. Upgrade Compatibility
This version will automatically upgrade any previous version 5 or version 6 database. You may need to check the upgrade notes of earlier releases for any compatibility issues.
Databases in 6.300 format will retro-grade without manual changes to 6.208.
2. Changes
The following are the changes to existing functionality between this version and 6.208:
2.1. Enhanced Decomposition in Stochastic Hydro Modelling
A state-of-the-art enhancement has been introduced to the optimization of long-term storage by MT Schedule and ST Schedule. When Storage Decomposition Method = "Shadow Prices" and MT Schedule is run with Stochastic Risk Sample Count > 1 and Stochastic Method ="Scenario-wise Decomposition" or "Independent Samples" the decomposition is done by computing Bender's cuts describing the multi-dimensional water value surface (or "Future Cost Function"). This greatly improves the robustness of ST Schedule storage optimization and is similar to the approach used by traditional stochastic dual dynamic programming.
2.2. Memory and Performance Improvements
The simulation engine code has been improved and now consumes less memory on large databases.
3. Features
3.1. Gas Model and Gas-electric Cooptimization
This version introduces the integrated Gas and Electric model described in the Gas Modelling article. The Gas model is enabled throughout the simulation from capacity planning in LT Plan through to short-term optimization in ST Schedule. The integrated model co-optimizes electric and gas expansion and production decisions simultaneously.
3.2. Decision Variable Class
The new Decision Variable class allows you to create generic variables in the mathematical programming problem in a similar way to Constraint for generic constraints. The feature supports linear and integer decisions and time-lagged coefficients, allowing you to create models of system components that are not part of the 'native' functionality.
3.3. Global Class
The new Global class exposes a number of simulation-wide settings that were previously unavailable. It also implements user-defined Future Cost Function for hydro optimization.
3.4. Multi-stage Stochastic Optimization
Support for multi-stage stochastic optimization has been introduced. The scenario tree parameters are defined on the Global class and currently work with all production simulation related non-anticipativity constraints. See the Variable and Unit Commitment topics for details.
3.5. Multi-level Interleaved Simulation
Model Interleaved simulation now works with any number of nested interleaved processes. For example, you can now run day-ahead, hour-ahead and real-time simulations in one interleaved simulation.
3.6. Heat Storage
The generator class has been enhanced to support storage of heat for CHP plant. See the articles Combined Heat and Power and Heat Storage.
3.7. Fuel Stockpiles
The fuel class now supports modelling of fuel inventory (stockpiles).
3.8. AC Line Expansion
LT Plan now supports expansion of the transmission network with ac and dc lines. See the new property Type for details.
3.9. Constraints on Risk
In portfolio optimization you can now define constraints on the level of 'risk' (variance in Net Profit) from a stochastic optimization. See the property Formulate Risk for details.
3.10. Coefficients for Modelling Flexibility
3.11. Hour Constraint Types and Reporting
To improve decomposition of constraints such as hydro energy in models where ST Schedule is sub-hourly and particularly for very short dispatch intervals like 10 minutes, a new Constraint RHS Hour type has been introduced. You can define constraints of hour type but also, which are useful for sub-hourly modelling and also report summary data by hour, again useful for sub-hourly modelling.
3.12. Condition Enhancements and Multiple Forecasts Support
The new Condition properties Step Hour Active From and Step Hours Active allow a Condition to activate depending on the hour number in a step. Since you can now combine Condition with Variable when defining a property this means that the values read in to a property can change mid-step, which allow you to change for example from an intra-day load forecast to day-ahead forecast. See the Unit Commitment article for details.
4. User Interface
There are no significant changes to the user interface, but performance has been improved especially on large databases.
