  1. Barcelona 12-15 May 2003 BUSINESS BENEFITS OF DMS SOFTWARE APPLICATION IN COMPETITIVE DISTRIBUTION KATIC--YU -- Session 6 – Block 3 – Paper presentation 1

  2. Barcelona 12-15 May 2003 Distribution Management System - important tools for cost reduction and revenue increase in open market. KATIC--YU -- Session 6 – Block 3 – Paper presentation 2

  3. Barcelona 12-15 May 2003 • Dynamic Mimic Diagram • Dispatching Tools • State Estimation Tool • Operation Tools • Optimization Tools • Engineering Analyses Tools DMS software: KATIC--YU -- Session 6 – Block 3 – Paper presentation 3

  4. Barcelona 12-15 May 2003 • Distrib.network contains loops but is radially operated • ONR objective - power losses minimization • Meshed network algorithm + opening of branches • Reduction of power losses - 6 to 18 % in examples • The profit approx. 0,5 % - relative to DC’s annual power purchase costs Optimal Network Reconfiguration (ONR) KATIC--YU -- Session 6 – Block 3 – Paper presentation 4

  5. Barcelona 12-15 May 2003 • OVC - centralized control of voltages and feeder losses • OVC objectives - minimization of consumers damage or voltage deviations andpower losses • Seasonal optimal settings of tapping boosts (OVTCT) • On-line correction of MV bus (source) voltage (ULTCT) • The better voltage quality in network is realized with 2 % increase of DC’s revenue Optimal Voltage Control (OVC) KATIC--YU -- Session 6 – Block 3 – Paper presentation 5

  6. Barcelona 12-15 May 2003 • Mutual influence - application should be coordinated • Correct order - first ONR than OVC • Corresponding objectives - power losses and damage min. • Improvements in network - the best in coordination case • The example of Futog network - 13,3 % reduction of power losses and 2,5 % revenue increase - during the season Coordination of ONR and OVC KATIC--YU -- Session 6 – Block 3 – Paper presentation 6

  7. Barcelona 12-15 May 2003 • PROFIT of ONR and OVC application is 2,5 % relative to DC’s annual power purchase cost • Total benefits of DMS application up to 5 % • Investments in DMS software tools are relatively small - 1000 $/MW of distribution network peak load or 0,5 % relative to DC’s annual power purchase cost Benefits of DMS application KATIC--YU -- Session 6 – Block 3 – Paper presentation 7

  8. Barcelona 12-15 May 2003 DMS Software Tools KATIC--YU -- Session 6 – Block 3 – Paper presentation 8

  9. Barcelona 12-15 May 2003 • The business benefits of DMS software are very high • DMS software - small investments - high profit • Network construction - high investments - small profit • DMS software - important tool in the race for the profit in the competitive marketplace CONCLUSION KATIC--YU -- Session 6 – Block 3 – Paper presentation 9
