Transmission System Operator Security Cooperation (TSC) 2

Agenda

TSC Vision / Capacity Management, European Utility Week, Amsterdam, 2013

1. TSC – who we are and where we want to go

2. Integrated Capacity Management – from tinkering holes to holistic thinking

Long-term to hourly forecasting

Common Grid Model

Grid Security Assessment

Capacity Calculation

3. Discussion

Transmission System Operator Security Cooperation (TSC)

TSC TSOs and their mission: Reliable, safe and efficient power for Europe.

TSC Vision / Capacity Management, European Utility Week, Amsterdam, 2013 3


Launched in December 2008

Cooperation to foster regional European coordination for system security

Decentralised approach (grid security and approval of remedial actions)

TSOs remain responsible for system security incl. operational planning

TSC's TSOs cover 10 European countries with about 185 million inhabitants and 1.13 million square kilometres.

New: Joint Office in Munich (24/7)

Open to the participation of other TSOs

Our initiative



Strong partnership of equals: TSOs within TSC

5 TSC Vision / Capacity Management, European Utility Week, Amsterdam, 2013

“ ”


“Good leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion.”

JACK WELSH



To ensure keeping a high level of overall system security in European electricity grid

To further enhance operational cooperation amongst TSO

To be best in class service provider for grid security assessment and capacity calculation

To support member TSOs to provide competitive and reliable services

To help TSOs to better manage their expanding operations

7

Our mission



Our vision


TSC grants member TSOs with long-term to real-time control over their operations, with respect to integrating wind energy and handling increases in cross-border trading and electricity transmission.


TSC TSOs – Joint Office



The TSC IT Platform delivers valuable data to TSOs and security initiatives (centralised or decentralised)

TSC is compatible with all (TSO-internal) forms of organization

TSC is extendable at will to other TSOs (also in other synchronous areas)

Capacity Management Module means a module containing up to date available Cross Zonal Capacity in real time for allocating Cross Zonal Capacity in a continuous manner.

ENTSO-E GLOSSARY, NETWORK CODES



Capacity Management is the process of planning, analyzing, sizing, and optimizing capacity to satisfy (current and future agreed) demand in a timely manner and in the most efficient way possible.

European LT scenario production

Individual LT case production

Merging individual cases

Calculation and allocation of LT-capacities


The harmonisation of individual grid models allows optimised use of available capacities.

The power grid security assessment is an indices system to prevent accidents and secure safety of supply. There are five kinds of indices: Capability of supplying power safely Static voltage security Topological vulnerability Transient security and Risk indices

Overload Low voltage Voltage collapse Angle instability …

The evaluation results are subjective and dynamic.

TSC on the way to become a European capacity calculation centre

Service provider linked to capacity calculation

One single interface to regional calculation

Data hub for necessary information

Knowledge provider

IT hosting entity or SPOC

TSC’s TSOs agreed to facilitate the transfer of capacity calculation functions for CWE, CEE and Northern Italian borders form SSC & CAO to TSC

18

Capacity Calculation (D-2F)


Service provider

Single interface to the regional cap calc

Data hub

Knowledge provider

IT hosting entity or SPOC


Need: Increase of uncertainties, esp. renewables, new devices (PST, HVDC), Intraday Market

Objectives

Continuous & automatic update of forecast data and security analysis results for coming hours

Detect any potential issue on the grid: anticipation

Provide information to the TSOs so that they can implement remedial actions on time

Ask for power plants to start

Cancellation of outage

Cross-border remedial actions, redispatching ...

19

Intra Day Congestion Forecast (IDCF)



Improved/additional services


As from 1 July 2013, 24/7 rolling forecast process in trial run

CTDS Users check and assess the quality of results (model contains remedial actions etc.)

CTDS Operation for IDCF rolling forecast performed fully automatically

Conference calls to discuss the results of IDCF contingency assessment on demand

Parallel operation of DACF and IDCF Rolling Forecast Process


TSOs developed a future proof planning process

Process follows ENTSO-E NC OPS requirements

Planning process is aligned long term system development procedures at each TSC and ENTSO-E (TYNDP)

TSO developed a standardised machine and human readable data exchange format

Interfaces to Risk Assessment Tools

You can't just simply ‘plan’ for capacity and leave it at that. Capacity needs to be managed proactively with proper monitoring, alerting, and optimization.
