Day-Ahead Bidding with Multiple Short-Term Markets (MultiSharm)

Day-Ahead Bidding with Multiple Short-Term Markets (MultiSharm)

This project aims at learning how hydropower producers should bid in day-ahead markets that are integrated in a sequence of balancing markets.

Project background

The European power system is expected to become more integrated
and include a larger share of intermittent renewable production. This
development is driven by EU environmental targets and ambitions. In
Norway, new cables to Europe, tighter market coupling and increased
contributions from intermittent production is expected to give increased
price volatility, larger volumes and higher prices in balancing markets. This
will increase the importance and profit potential of a consistent view on
trade in all short-term markets. The producers' ability to optimally bid their
resources in a broad and complex range of markets is a premise for the
efficient utilization of Norwegian hydropower resources and the ability to
provide balancing flexibility to the system.

Project scope

This project aims at learning how hydropower producers should bid in
day-ahead markets that are integrated in a sequence of balancing markets.
This will be achieved by studying optimal behaviour in short-term markets
by the use of research models. The next step will be to extend the detailed
hydropower scheduling models currently used by the industry with balancing
markets based on the knowledge gained from the research models.
Providing a consistent description of market and inflow uncertainty is a
premise for both these steps.


We define the following major research tasks:

  1. Modelling of uncertainty; how to model inflow and prices in the different short-term markets and their interdependence is crucial as this will be the input to the bidding models.

  2. Multi-market modelling; there is a need to develop general knowledge about integrated markets, how to model their co-existence and how to obtain consistent and robust bidding strategies.

  3. Hydropower bidding model; the modelling of balancing capabilities in the hydropower production system will be aligned with the balancing market extensions.
