Latest developments
The project has been redefined From Flow-Based Capacity Calculation Methodology Project ID CCM is formally included
CNTC is formally included
CCM Proposal process formally included
Development of industrialized CC tool is shifted to the RSC
The FB-prototype is now fully developed, but not fully implemented Final GSK strategy not implemented
FRMs calculated, but not included
Operators are consulted, not personally involved
Adjustment and learning process is ongoing Continuous FB capacity calculations from week 01-2016 (Ex week 24-28)
Threshold on CNEs implemented from week 40 → Relaxed domains
Not operational domains yet, data quality is an issue • Error detection and corrections in the preliminary IGMs/CGMs
• Error detection and corrections on CNE definitions
The quality of the preliminary CGM is an
issue which will be solved by the CGMES
AC Load flow 63%
Data corrupt
18%
Missing hours 11%
Unknown method
7%
DC Load flow 1%
AC and DC load flow:
results with sufficient quality
Unknown method:
AC or DC load flow (earlier
script did not recognized
this)
Missing hour:
No CGM data model
Data corrupt:
The CGM, the FB prototype
data or the PX have
identified errors
71 % sufficient quality data ≈ 2700 hours for week 1-23
CNE definition is a learning process
Critical Network Elements (CNEs) are used for defining current NTCs in an operator-driven process
Current CNEs are used in the prototype tools
Operators makes choices based on best practice and experience (and there are different practices between the TSOs)
Not a "one-to-one" relation between the defined CNEs and the resulting NTCs
FB and CNTC is establishing a common mathematical approach for Calculating market capacities
The relation between current CNEs and NTCs are revealed, and overloads are detected
Non-relevant CNEs are revealed
The need for new CNEs are revealed

Headline Content
Proposal of the methodology
For Flow based and CNTC in a DA and ID time frame: - Detailed description of the capacity calculation approach: 1. a mathematical description of the applied capacity calculation approach with different capacity calculation
inputs; 2. rules for avoiding undue discrimination between internal and cross-zonal exchanges 3. rules for taking into account previously allocated cross-zonal capacity; 4. rules on the adjustment of power flows on critical network elements or of cross-zonal capacity due to remedial
actions 5. for the flow-based approach, a mathematical description of the calculation of power transfer distribution
factors and of the calculation of available margins on critical network elements; 6. for the coordinated net transmission capacity approach, the rules for calculating cross-zonal capacity, including
the rules for efficiently sharing the power flow capabilities of critical network elements among different bidding zone borders;
7. where the power flows on critical network elements are influenced by cross-zonal power exchanges in different capacity calculation regions, the rules for sharing the power flow capabilities of critical network elements among different capacity calculation regions in order to accommodate these flows.
- Methodologies for the calculation of the inputs to capacity calculation will include the following parameters: 1. a methodology for determining the reliability margin; 2. the methodologies for determining operational security limits, contingencies relevant to capacity calculation
and allocation constraints; 3. the methodology for determining the generation shift keys; and 4. the methodology for determining remedial actions to be considered in capacity calculation

Impact assessment of proposal (1/2)
Headline Content
Introduction - Approach to demonstrating impact
Impact on the objectives of the CACM GL
- An assessment of the impact on the objectives of the CACM GL, article 3: - promoting effective competition in the generation, trading and supply of electricity; - ensuring optimal use of the transmission infrastructure; - ensuring operational security; - optimising the calculation and allocation of cross-zonal capacity; - ensuring fair and non-discriminatory treatment of TSOs, NEMOs, the Agency, regulatory
authorities and market participants; - ensuring and enhancing the transparency and reliability of information; - contributing to the efficient long-term operation and development of the electricity transmission
system and electricity sector in the Union; - respecting the need for a fair and orderly market and fair and orderly price formation; - creating a level playing field for NEMOs; - providing non-discriminatory access to cross-zonal capacity.
Approach: - outline our understanding of definition of each of the objectives - do the assessment based on our definition
Headline Content
Quantitative impact indicators
- Socioeconomic welfare of FB per country/per bidding zone per element (PS, CS, CR)
- Impact on capacity domains and cross bidding zone exchange - Spot prices - Selected cases illustrating impact and benefit (in case FB is the selected
methodology)

Efficiently sharing the technical grid capacity on the borders
FB/CNTC comparison
CNTC approach
Coordinated net transfer capacity (CNTC) approach is an advanced and
highly automated version of current NTC
Calculations based on the CGM, basic AC load flow and dynamic
simulations
Aim to calculate maximum transmission capacity by taking into account
following items defined by TSOs
Contingencies
GSKs
Operational security limits
Remedial actions

The initial calculation of the technical max flow on a border provides points at the edge/border of the Security Domain (illustrated by a linear domain)
The max technical flow on each border are not simultaneously available in a meshed grid

The rule "capture the Base Case" will provide CNTC values that permits the base Case to be realized
Accurate forecasting is crucial (as it is in the current and all NTC solution)
If the base case is in a corner (see figure) the CNTC domain might be extremely narrow (NTC on B>C is zero)

Stakeholder Tool
Tool for examining the effect on flows/possible net
positions from PTDFs
CNEs are fully anonymized – randomized numbering
This is a first draft – comments/suggestions are welcome
Stakeholder tool
GUI - Test feasible net positions
cells that can be editted
the white cells indicate the Nordic synchronous area; the grey cells the DK1 synchronous area
the orange texts indicate that the cell value is computed from another. Indeed, this is applied for DC cables: the power injected on one side is emitted at the other
A check on the power balance in each synchronous area is performed;
GUI - Test feasible net positions If the net positions, that you entered, fit within the FB domain, the message that 'Transmission system not congested' appears. Otherwise, the message 'Transmission system congested' appears in red.
The net position, that you entered, appears in the Nordic map in bold. Above this value, the maximum net position (feasible within the FB domain) is shown. Below this value the min net position (feasible within the FB domain) is shown.
The border flows (according to the FB model), resulting from the net positions that you entered, are shown in the map.
FB parameters
the net positions that you filled in on the 'GUI'
the flows induced on the CNEs (PTDF matrix * net positions)
is the CNE congested? Or in other words: is the resulting flow larger than the RAM ( remaining available margin, the flow that is allowed to be used by the market transactions)?
the PTDF factors of the CNEs
Min/Max Net Positions & Border Flows
The tool includes information on Min/Max Net Position
per bidding zone
Not simultaneously feasible
The border flows (according to the FB model), resulting
from the net positions that you entered, are computed.
Those values are presented in the 'GUI'
