Capacity Auction System is designed to provide explicit bilateral and multilateral capacity auctions as well as coordinated explicit load-flow based capacity auctions. Further the system has a market coupling module (implicit auctions) included, i.e. it has the possibility to include order books from power exchanges into the clearing procedure. Within the system there are several modules in addition to the different auction modules. Additionally to the modules shown below in Figure 1, there is another module for scheduling support. Although these modules should be seen as an entity, all of them can be run separately.
As mentioned above, the software is a highly flexible solution for conducting different types of auctions. Beside different types of capacity and energy auctions, other auctions types like e.g. CO2 emission auctions can easily be implemented and integrated. Each type of auction means in this context that following attributes can freely be combined:
Â¢ Any product: i.e. any freely definable time period, like yearly, monthly, daily, intraday.
Â¢ Any number of market areas: bilateral, multilateral.
Â¢ Any transportation-cost constraint: i.e. load-flow based, NTC-based.
Â¢ Any auction method: i.e. explicit, implicit, hybrid.
Additionally different bid types are implemented, like:
Â¢ Divisible bids
Â¢ Indivisible Bids (fill-or-kill, all-or-nothing)
Â¢ Linked bids (all-or-nothing for a combination of bids)
Â¢ Standard block bids (e.g. base, peak)
Â¢ Freely definable block bids
