4. • • • • • Optimal Network Reconfiguration (ONR)
Barcelona May 2003
Optimal Network Reconfiguration (ONR) •
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

5. • • • • • Optimal Voltage Control (OVC)
Barcelona May 2003
Optimal Voltage Control (OVC) •
OVC - centralized control of voltages and feeder losses •
OVC objectives - minimization of consumers damage or voltage deviations and power 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

6. • • • • • Coordination of ONR and OVC
Barcelona May 2003
Coordination of ONR and OVC •
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

7. • • • Benefits of DMS application
Barcelona May 2003
Benefits of DMS application •
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

Barcelona May 2003
CONCLUSION •
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
