Integrated Resource and Resilience Planning (IRRP)
The main objective of OptGen is to support countries globally to conduct integrated energy planning systematically, especially for a
cleaner, affordable, and resilient energy future. In this context, the word resilience is drawing a lot of attention. One example is
the recent energy crisis in Texas, in 2021, where an extreme weather event followed by shocks in supply (due to unavailability of
some generators) and in demand (caused by the need to heat the houses) put a solid electrical market in stress.
Due to the importance of carrying out expansion planning with resilience, we have added the “Resilience (Critical scenarios)” option in
OptGen. This option enables the consideration of high-impact low probability events during the expansion planning task.
Critical scenarios
The decomposition procedure adopted by OptGen adds feasibility cuts to the optimal expansion plan by solving dispatch problems that minimize the energy deficit for sub-horizons under pre-defined extreme conditions.
User defined extreme conditions
User can choose a combination of sensitivities in SDDP for a specific scenario using factors for load, outages of thermal and renewables, fuel costs, interconnections capacities and inflows.
New scenario from existing forward series
These scenarios are later associated to a time span in OptGen and to a forward series.
Feasibility of each extreme condition
During the convergence, OptGen will report the amount of infeasibility (load curtailment) for each user-defined extreme condition for each candidate plan obtained during the iterative process.
New candidate projects
Starting with version 17.0, SDDP can explicitly model the full hydrogen supply chain and its integration into the power system. Besides that, a detailed representation of CSP plants has been included. This version of OptGen includes those technologies as candidate projects for the expansion planning optimization
Hydrogen supply chain
The main chain elements are represented such as: (i) producers; (ii) transportation; (iii) storage and (iv) price-responsive hydrogen demand.
General commodities supply chain
Besides Hydrogen, any commodity can be represented (natural gas, grains, oil and others)
CSP plants
A detailed modelling of CSP plant inside OptGen and SDDP allows it to be a candidate project
New dashboard
The dashboard has been redesigned to include new information such as expansion results and new charts with solution quality.
Expansion and simulation results
OptGen’s dashboard is now very informative, having results from both phases (expansion planning task & expansion plan simulation)
Convergence graph
A new graph illustrating the lower- and upper-bound of the iterative process of solution strategy OptGen 1.
OptGen 2 operative results
New charts including results of the operative module of OptGen 2.
