Key focus points upcoming year CCM methodology and regulatory approval process Stakeholder involvement ID CNTC proof of principle Data quality in the simulations / learning-by-doing process RSC CGMs will be available in the coarse of 2018 Support the CCM implementation at the RSC Initiate the development of the FCA CCM The current status will be elaborated on the next slides

Nordic CCM proposal CCM methodology and regulatory approval process For the Day Ahead timeframe The Nordic TSOs propose to implement a Flow Based capacity calculation approach for the Day Ahead Market timeframe For the Intraday timeframe As the long-term solution, the Nordic TSOs propose to implement a Flow Based approach for the intraday timeframe as soon as the intraday market platform is technically able to utilize flow-based capacities. As an interim solution, the Nordic TSOs propose to implement a coordinated net transmission capacity approach for the intraday market timeframe.

CCM project and Nordic RSC Support the CCM implementation at the RSC CCM project - CCM methodology development Nordic RSC - CCM implementation (amongst others)

Flow-based (FB) in Europe Support the CCM implementation at the RSC Nordic: FB MC * Project in progress FB is live in CWE as of May 21, 2015 Norway Sweden Finland FB is not an off-theshelf product! Ireland CWE: FB MC * Live as of May 21, 2015 Portugal United Kingdom Spain Netherlands France Andorra Belgium Luxembourg Denmark Switzerland Germany Liechtenstein Monaco San Marino Czech Rep Slovakia Austria Italy Vatican Slovenia Poland Hungary CroatiaBosnia and H Montenegro Serbia Albania Greece Estonia Lithuania Macedonia Latvia Romania Bulgaria Moldova Russia Baltic: FB MC * Pre-feasibility study finalized Belarus CEE: FB MC * CWE and CEE are now merged into one CCR (CORE region) Ukraine Turkey Georgia Azerbaijan Armenia Kazakhstan Malta Cyprus

Characteristics of the Nordic FB / differences with CWE Support the CCM implementation at the RSC Advanced Hybrid Coupling is applied on all DC links Number of Bidding Zones: 26 Nordic bidding zones: 12 Virtual bidding zones: 14 Due to the high dimensionality of the FB domain, the vertices and volume cannot be (easily) computed Two synchronous areas DK1 is part of the continental European synchronous system FB plain is applied Running the intuitive patch poses issues given the high dimensionality of the FB domain (overconstraining the system)

Characteristics of the Nordic FB / differences with CWE Support the CCM implementation at the RSC CNEs: Tielines and internal network elements Cuts: multiple lines modelled as a single CNE, with its own RAM and PTDFs Voltage and dynamic constraints Number of presolved FB constraints Around 85 Sensitivity threshold 15 % is applied at the moment

Presentation of the Nordic RSC December 11 th 2017 CCM Stakeholder Forum

Nordic Regional Security Coordination Background Enhancing the Nordic cooperation Implement European Network Code Purpose is to support the Nordic TSOs: Maintain security of supply in the Nordic area Optimize the availability of the Nordic Power Grid By calculate capacities for the Nordic area The RSC is an advisor, the decision remains with the TSO's.

Nordic RSC, Joint Office in Copenhagen

Regional Security Coordination in Europe Existing and upcoming RSCs

The five services of the Nordic RSC Coordinated Capacity Calculation (CCC) Coordinated Security Analysis (CSA) Outage Planning Coordination (OPC) Short and Medium-Term Adequacy (SMTA) Common Grid Model (CGM) Based on the Individual Grid Models (IGM)

First steps for the five services Coordinated Capacity Calculation (CCC): Joint release of capacities to the Power Exchange(s) Coordinated Security Analysis (CSA): A daily analysis, based on the Nordic CGM Outage Planning Coordination (OPC): Weekly coordination for upcoming 4 weeks Short and Medium-Term Adequacy (SMTA): Daily assessment for upcoming seven days. Cross-regional assessment with other RSCs Common Grid Model (CGM): (Covered in next slides).

Why a Grid Model? Today Snap shot of today to represent the day after tomorrow Tomorrow Forecast of the day after tomorrow to represent the day after tomorrow Today Day after tomorrow

Why a Grid Model? Better representation of the grid More accurate power flows More accurate capacities Better utilization of the grid & Increased operational security

Creating the Nordic CGM - 1 1D/ID: Market result NRVF PEVF 2D/YA: Forecasts Prealignment CGM Alignment Step 1: Alignment of power flow between the IGMs Purpose: All TSOs using aligned tie flows to create IGMs NB!! Different approaches for when the market results are available (ID and D-1) and when we don t have market results (D- 2 and YA)

D-2 CGM alignment TSOs Nordic RSC Master Alignment Agent (MAA) D-2 Forecasts D-1 Planned schedules D-2 Pre-Processed Data (PPD) CGMA result CGMA result D-2 IGM D-2 CGM

Creating the Nordic CGM - 2 YA: Outage planning coordination 2D: Day ahead capacity calculation 1D: Intraday capacity calculation and security analysis Creating IGM Send to NRSC ID: Security analysis and ad hoc analysis At the TSOs Step 2: All Nordic TSOs needs to create their IGMs The information in the CGM should support the business services that they support. Defined in CGMM IGMs are created on a common standard, CGMES, to make sure that they can be part of the CGM puzzle

Creating the Nordic CGM - 3 EQ TPSSH IGMs IGMs Boundary Set Targets for tieline flows Nordic CGM Step 3: Merging the Nordic IGMs into the Nordic CGM

Quality of the D-2 CGM Important factors that we are working on with the TSOs: 1. The input data from the TSOs to the pre-alignment function Implementation guides has been decided with the Nordic TSOs Splitting up the information on bidding zone (BZ) level 2. The quality of the D-2 IGMs Quality assurance of the grid models by defined rules The D-2 IGMs are checked against the aligned values before they are used for further processing 3. The quality of the D-2 CGM Quality assurance of the CGM by defined rules

Information needed for capacity calculation Contingencies Remedial actions GSKs / LSKs (generation and load shift keys) Reliability margins Operational security limits (thermal, voltage, dynamic stability etc.) Possible allocation constraints

Questions?

Transparency needs agreed upon by stakeholders in the Oct 11 Stakeholder Group meeting

Transparency needs agreed upon by stakeholders in the Oct 11 Stakeholder Group meeting As a minimum, each CNE should have a unique identifier ( name ) + information on the location where it is (i.e. in which bidding zone, or between which two bidding zones). Information on the critical outage, the scenario under which the CNE is monitored, is not relevant. The individual components of the RAMs (being the FRM, Fmax, Fref, RA, and FAV). The methodology to select CNEs (why are they a CNE?) + justification if internal CNEs are used; note that this is not needed for price forecasting, but to build trust The CWE transparency level should be the minimum in the Nordics.
