ratingLine Capacity Dynamic Line Rating (DLR)

DLR allows: To uncover the fullavailable line capacity (aka ampacity ) To get closer to the limit, with the same level of security

From darkness to light.

Sag (Clearance) is the most critical limit to the operation of anoverhead-line

Typically maximum sag will be reached at temperatures belowmaximum conductor temperature Direct sag measurement is the safest monitoring method REAL-TIME measurement of Sag: the only DLR system closing the

loop with a direct measurement of Sag

Typical Results


13/34

Products/service offering:The Ampacimon Dynamic Line Rating suite

DLR planning software, performing rating estimations based on prevailingweather parameters. Typically identifies 5-15% ratings gains, no direct on-line measurements

The OHL vibrations sensor (patented)

Real-time data acquisition, sag and ampacity computation software

Short term (1-4h) ampacity forecast software

24-48h ampacity forecast software, using predicitive algorithms based onweather modeling combined with historical ampacity real-time acquisition

A full suite of products enabling T/DSO to maximize the useof their grid, fully integrated within their SCADA/EMS

Sag sensorMeasures lines vibrationsTransmits data through GSM or Xbee network

On-board wind measurement (patented)In average, one every 3- 5km (more if more complex terrain.less if flat !) Certified up to 400kV (500kV possible)

Captures Sag data in Real TimeComputes Real-time Ampacity for each monitored spanComputes line real-time ampacityDashboard of key line parameters for each monitored span


17/34

Computes a time- series based forecast ampacity over a 1 -4h horizonEliminates very short-term RT ampacity fluctuationsProvides dispatch center operators with a more practical information which can be fed directly into N-1 flow

simulators


18/34

Up to 60h-ahead ampacity forecastUses weather-based models, correlated with historical Real-Time ampacity measurementsStatistically reliable, Percentiles can be setUsed for inter-market operations and day-ahead dispatching plans

DLR Applications

19

REN integration

Accelerates wind farms integration (no need for new lines)Less curtailment => higher revenue for wind farms

Infrastructure deployment and optimizationQuick, significant, easy to deploy extra capacity until newinfrastructure is in place or while maintenance is performed

Market liquidity and security of supply

Increases X-border capacityGives visibility and transparency on available capacity oncritical linesIncreases security of supplyIncreases markets liquidity and price convergence


20/34

Maximize usage of existing OVH lines Particularly interesting for wind farms Example:

A TSO needs to connect 9MW extra wind farm capacity ona 63kV line (static rating 430Amp)New OHL would require new 24m investment, 5 yearsplan and deploymentdone in 3 months, costing 400k

Gains up to 50% in RT sufficient to debottleneck the line

REN integration


21/34

Increase security of supply with existing assets

Improve interconnections Example:

Belgium, faced with potential generation shortage needsto maximize interconnections with F and NL

Equip all 8 interconnections with and

D-2 forecast allows to increase total (3000MW) importcapacity by 10-15%

Up to 30% in Real TimeDeployed in 2 months, increase security of supply by300MW !

Infrastructure optimization


22/34

Monitors true available capacity, data can be shared withoperators/market participants Reliably forecast bottleneck interconnectors Increases price convergence at a fraction of the cost and time

of new OHL projects Can be combined with other flexibility devices

Example: Twenties project

Currently uses Ampacimons 1-4h forecast instead of static ratings in their 1/4h EMS Has been using Ampacilmon for 5 years Day-ahead forecasting on all interconnection lines being deployed

Looking for a economical solution to reduce expensive re-dispatch events on congested network links Has been using Ampacimon in real operations for 1 year, with a 4 months pay -back

Quick and economical solution to deal with significant congestion issues due to the integration of renewable energysources and the moratorium on nuclear energy

Smartzone project Considering use of Day-ahead forecast modules

Looking for a better alternative to the already installed Power Donuts

Twenties project, in combination with Distributed Temperature Sensing
