Accomodation of power system constraints with the market mechanism is encountered as a major challenge along the way toward implementation of different electricity market designs. Allocation of fixe or flow-dependent inter-zone trading capacities by the PX (power exchange) can not be accepted unreservedly. The paper is meant to show that a nodal electricity market design that is based on bids for local energy and a regulated transmission access including allocation of "entry-exit" transmission capacity would be the desired solution. The market players could easily optimize their portfolio while the TSOs (transmission system operators) are requested to mobilize the network's in-built flexibility to increase the cross zonal capacity. In the proposed market design, the PX's allocation of trading capacity is clearly separate from the TSO's management of the power system operational constraint5. Clear operator roles would enlarge access to electricity market as well as market integration of variable RESs (renewable energy sources) that are critically dependent on short notice access to regionat markets, 展开更多
