3.Introducing EUPHEMIA EUPHEMIA is the algorithm that has been developed to solve the problem associated with the coupling of the day-ahead power markets in the PCR region. First, Market participants start by submitting their orders to their respective power Exchange. All these orders are collected and submitted to EUPHEMIA

Bidding zones can exchange energy between them in an ATC model (Section 4.2), a flow based model (Section 4.3) or a hybrid model (combination of the previous two models).

The common price coupling algorithm, called PCR EUPHEMIA, is used in the Single Day-Ahead Coupling to calculate power prices across Europe, while implicitly allocating auction-based cross-border capacity.

The SDAC makes use of a common price coupling algorithm, called PCR EUPHEMIA, to calculate electricity prices across Europe and to implicitly allocate auction-based cross-border capacity. Input data to PCR EUPHEMIA are the network capacities and constraints provided by the TSOs and the bids and offers provided by the NEMOs.

EUPHEMIA Algorithm. One of the key elements of PCR project is the development of a single price coupling algorithm, which adopts the name of EUPHEMIA (acronym of Pan-European Hybrid Electricity Market Integration Algorithm).

EUPHEMIA is an algorithm that solves the market coupling problem on the PCR perimeter. EUPHEMIA stands for: EU + Pan-european Hybrid Electricity Market Integration Algorithm. INTERCON. Each PX (Market) operates several bidding areas. All bidding areas are matched at the same time. A different price can be obtained for each bidding area.

The solution implemented in EUPHEMIA within flow-based market coupling (FBMC) follows the curtailment sharing principles that already existed under ATC/NTC. The objective is to equalise the ratio of curtailment (~Energy Non Served (ENS)/Total volume of price-taking orders) between bidding zones as much as possible. I.2. FLOW FACTOR COMPETITION
