| contents | This paper presents the coordination of two congestion management instruments - capacity limitation contracts (CLCs) and redispatch contracts (RCs) - as a risk-aware resource allocation problem. We propose that the advantages and drawbacks of these instruments can be represented as operational risk profiles and can be balanced through coordination. To this end, we develop a chance-constrained two-stage stochastic mixed-integer program for a system operator procuring flexibility from an aggregator managing a fleet of electric vehicles (EVs). The model captures uncertainty in EV charging and redispatch market conditions, using real order book data from the Dutch redispatch market (GOPACS).
Results indicate that combining CLCs and RCs is generally the most cost-effective approach to mitigate risks associated with each instrument, but the optimal mix depends on fleet size and RC activation timing. Large uncertainty about EV loading increases RC activation intraday to correct for forecasting errors at the earlier CLC stage. For large fleet sizes (e.g. 25.000) the optimal policy limits redispatch due to market liquidity risks in the immature redispatch market. This risk increases for later redispatch activation due to shrinking trading windows for redispatch products. These findings highlight how various sources of uncertainty can impact the optimal trade-off between congestion management instruments. |
