Why does FB make a difference?
All flows induced by commercial exchanges, including transit flows, are controlled by the market mechanism. Transit flows are not controlled by the market mechanism in (C)NTC
No need to "hold back" capacity in FB due to uncontrolled and uncertain commercial transit flows – More of the grid capacity might be offered to the market
The TSO does not have to prioritize where to assign capacity in advance of the market solution due to uncertainty – All technically feasible trade options are offered to the market
The market might be offered more commercial trade opportunities in FB than in (C)NTC provided an equal level of operational security
export
import
Transit flow
The scope has changed
1. The FB project has been given responsibility for the
CNTC prototype development, CNTC market simulation
and comparison to FB. A new WG4 has been established
to develop and manage this
2. A Nordic RSCI/RSC (Regional Security Coordination
Initiative) is being established.
The boundaries between the FB project and the RSCI in terms of
IT-development is currently not clear, including responsibility for the
development of the industrialized FB tool
Current main focus in the FB project
1. Make the FB parameter calculation, validation and market simulation process work continuously, and with sufficient accuracy:
1. Create the hourly common grid models Upload hourly IGMs
Merge IGMs to create CGMs
2. Determine available grid capacity Define hourly grid capacities (CNE-limits)
3. Calculate and validate the flow based parameters Calculate hourly PTDF matrixes
Verify the resulting hourly security domain and extract PX data
4. Perform the simulations and compare results Upload PX data and calculate hourly market equilibriums
Compare FB/NTC/CNTC market results
2. Develop a CNTC prototype tool based on the FB GSKs, Grid Model and CNEs
3. Define the FB specific requirements for an industrialized FB tool
Tooling issues
The hourly grid models are not of industry quality until the upcoming European CGM is ready. Mitigation actions have been put in place
Topology changes are necessary for creating a base case, but causes convergence problems in the prototype CGM Forecasting is not developed
FRM methodology is developed but not implemented
Remedial actions/system protection schemes are implemented

Case 2: 21st of January 2016 16:00-17:00
Basic FB pricing principles (1/3)
Same price coupling algorithm in both FB and NTC
MAX Welfare =
Subject to constraints
Consumer surplus
Producer surplus
Congestion revenue
Example of an exchange from a low price area to a high price area
Basic FB pricing principles (2/3)
FB constraints Power Transfer Distribution Factor (PTDF) -
indicates how much MWs are used by the net
positions resulting from the trades
Remaining Available Margin (RAM) - number
of MWs that can be used by the trades
PTDF matrix Area A (SE2) Area B (SE1) Area C (NO3) RAM
Line X 0,11 0,098 0,15 15
• An exchange of 1 MW from C to A uses (0,15 – 0,11)= 0,04 MW 15/0,04= 355 MW can be exchanged • An exchange of 1 MW from B to A uses (0,098 -0,11)= - 0,012 MW relieves the congestion on line X with 0,012 MW Each 1 MW between
B to A enables 0,3 MW (0,012/0,04) exchange from C to A

Basic FB pricing principles (3/3)
Equilibrium condition
Marginal Price A – Marginal Price B = (PTDFB – PTDFA ) x
Shadow price
For a solution to be optimal, this condition must be fulfilled
Uniform prices in FB
No congestion (or/and) shadow price equals zero
Same impact on CNE (usage of margin) same PTDF-value
Simplified example calculation of price
differences
Exchange from B to A: • the difference between the PTDFs is
-0,012 • the shadow price on line X is 100 €/MW • the price difference between area A and B
can then be calculated: • Marginal Price A – Marginal Price B =
(PTDFB – PTDFA ) x Shadow price = -0,012*100= -1,2 €/MWh
Exchange from C to A: • the difference between the PTDFs is 0,04 • the shadow price on line X is 100 €/MW • the price difference between area A and C
can then be calculated: • Marginal Price A – Marginal Price C =
(PTDFC – PTDFA ) x Shadow price = 0,04*100= 4 €/MWh

Scope of market simulations
The Euphemia algorithm is used for market simulations
Geographical scope is limited to:
Nordic countries
Baltic countries
Central West Europe (Germany, Belgium, Netherlands, France)
Great Britain
Poland
Russia (Import/export capacity to Nordic and Baltic countries)
Belarus (Import/export capacity to Baltic countries)
Flow Based parameters available only for Nordic countries,
the HVDC interconnectors, and the CWE region
The market simulation results are only preliminary
Case 1: 1st of January 2015 05:00-06:00
Summary
General observations FB manages the west-coast cut more efficiently by taking into account the
impact on the specific CNE in the allocation
Import flow from continental Europe to Nordic synchronous system • SwePol link capacity set to 0
• Import on Baltic Cable reduced by TSOs
High wind power output (3 GWh in Denmark)
NTC results: SE and FI constitute one price area,
NO3 and NO4 constitute one price area,
NO1, NO5 and NO2 one price area,
DK constitutes one price area
FB results: Higher welfare in the FB solution
Different prices in all Nordic areas
More import from Germany, transit through Denmark
Case 2: 21st of January 2016 16:00-17:00
Summary
General observations This case shows how prices are affected in the whole Nordic region by a
CNE with a high shadow price
The FB approach manages to lower the prices compared to the NTC approach in most bidding zones due to a different way of managing the congestion
High consumption in Nordic countries (68 GW)
Low wind output 618 MW SE, 347 MW DK
Capacity on SwePol link from PL to SE4 set to 0
NTC results EE, DK2, FI, NO1, NO3, NO4, SE1-4 constitute one price area
NO2, NO5 and DK1 constitute one price area
FB results Higher welfare in FB solution
Different prices in all Nordic bidding zones
More import to Nordic region
High shadow prices on some CNEs
Example price difference between areas
and impact of shadow prices
Explanation of price difference SE4-DK2 in FB
The price difference is explained by one CNE in Sweden with
a high shadow price
The price difference between DK2 and SE4 is 5,65 €/MWh
Small difference in usage of margin / difference in PTDFs
between DK2 and SE4
Price difference SE4 – DK2 = Shadow Price x difference in
PTDF = 5,65 = 770 x (-0.06479 – (-0.07212))

Background (1/2)
According to CACM guideline, there are two permissible approaches for cross zonal capacity calculation Flow based (FB)
Coordinated net transmission capacity (CNTC)
FB approach should be used as a primary approach in regions where cross zonal capacity between bidding zones is highly interdependent
CNTC approach should only be applied in regions where cross zonal capacity is less interdependent and
it can be shown that FB approach would not bring added value
Background (2/2)
Flow Based project has been assigned to
develop a prototype version of the CNTC methodology
compare FB and CNTC approaches
Framework for CNTC approach
The aim is to develop current NTC approach to fulfill the requirements of CACM guideline for the purpose of comparing efficiency between FB and CNTC approaches
Same common grid model (CGM) as in FB
Same critical network elements (CNEs) as in FB Same level of operational security
Same max capacities, security margins, remedial actions etc
Cross zonal capacities calculated separately for each hour
Target: Highly automated CNTC calculation process
Pros and cons of CNTC approach
Pros: Requirements of CACM are addressed
Current operational experience is maintained
Simple • the use of NTC values and the values itself are well-
established
Cons: Some manual workload for operational planning

calculation methodology, cf. article 20,1
No legal obligation to demonstrate that FB would be more efficient
compared to the coordinated C-NTC approach and assuming the
same level of operational security in the concerned region.
However, the TSOs concerned shall still submit a proposal for capacity
calculation methodology including a detailed explanation for key parameters, cf.
article 21-25 of CACM
The Nordic TSOs go beyond the scope of CACM and provide for the
stakeholders and NRAs a throughout demonstration of FB
application, including an estimate for the socioeconomic benefit of
FB

2 RAM and the
components to
calculate the RAM ie
Fmax, FRM, FAV og Fref
with special emphasis
on FRM og FAV
Compared to todays NTC we need to understand which RAMs are chosen for the relevant grid elements and how they are derived. If: 𝑅𝐴𝑀=𝐹𝑚𝑎𝑥−𝐹𝑅𝑀−𝐹𝐴𝑉−𝐹𝑟𝑒𝑓 Fmax (max allowed flow) and Fref (flow at zero net positions) are technical terms, which need to be known, but we need to understand how the FRM (the reliability margin) and the FAV (the ability to manually adjust the RAM) are chosen.
3 CNE In order to understand how the flow based grid model reacts to different
situations, we need to know about the critical branches, in which or
between which zones they are located, when and why they are activated.
We also need to understand the connection between UMMs (REMIT
relevant information) and the CNEs: otherwise information in the UMMs
about grid maintenance will be difficult to use to predict the impact of
grid maintenance on the market.

4 GSK We need to have a basic understanding of how the GSK for all price areas
are derived and which assumption they follow. Since the GSK will affect
how the PDTF will react to the different situations, producers should at
least have a basic idea how they were set up. Since producers understand
best their own production logic, TSOs would also profit from the
producers input to set up realistic GSKs.
5 PDTF We need the PDTF to model the system and the prices. We do not just
need a PDTF for the next day but hydropoducers need also to have a
certain idea about price developments in the next week/month/quarter
and season in order to plan their reservoir use correctly.
6 Max Net Position /
Price zone
Important to give all stakeholders information about TSOs calculations on
import/export capacities per price zone. This is necessary for the
optimization of the hydropower reservoirs.
7 Capacities forecasts
between price zones
Both short term and long term forecasts are important for water value
calculations for hydro power producers
8 NTC and Max NTC This will give all stakeholders the opportunity to evaluate the FB results.

CNTC Calculations – Prototype Approach CNTC Calculations
Define CNE capacities (RAMs) and calculate
the security domain (The same as in Flow
Based)
Start with Max 𝑁𝑇𝐶𝐵𝑜𝑟𝑑𝑒𝑟
Define rules to adjust the Max 𝑁𝑇𝐶𝐵𝑜𝑟𝑑𝑒𝑟 to
fit the security domain
For both FB and CNTC, create rule to adjust
𝐹𝐴𝑉𝐶𝑁𝐸 to improve CNTCs if no relevant
overload-situations occur
Define rules for accepting some "unsecure"
NTCs in "unrealistic" market positions in
cases where "not accepting those NTCs" is
severely blocking relevant trades
Secure unsecure NTC values
Improve NTC values when possible
Allow for "unsecure" NTC in
"unrealistic" market situations if this
improve NTC values
