Considering that the existing setup of the European electricity marketspromotes the spatial coordination of neighbouring power systems only on theday-ahead market stage, regional system operators have to rely mainly on theirinternal balancing resources in order to guarantee system security. However, aspower systems are forced to operate closer to their technical limits, whereflexible generation becomes scarce, the conventional market paradigm may not beable to respond effectively on the wide range of uncertainty. The operationalflexibility of the power system depends both on the technical parameters of itscomponents, i.e., generators and transmission infrastructure, as well as on theoperational practices that make optimal use of the available assets. This workfocuses on alternative market designs that enable sharing of cross-borderbalancing resources between adjacent power systems through High Voltage DirectCurrent (HVDC) interconnections which provide increased controllability. Inthis context, we formulate a stochastic market-clearing algorithm that attainsfull spatio-temporal integration of reserve capacity, day-ahead and balancingmarkets. Against this benchmark we compare two deterministic market designswith varying degrees of coordination between the reserve capacity and energyservices, both followed by a real-time mechanism. Our study reveals theinefficiency of deterministic approaches as the shares of wind power increase.Nevertheless, enforcing a tighter coordination between the reserves and energytrading floors may improve considerably the expected system cost compared to asequential market design. Aiming to provide some insights for improvement ofthe sequential market-clearing, we analyse the effect of explicit transmissionallocation between energy and reserves for different HVDC capacities andidentify the market dynamics that dictate the optimal ratio.
