5. Why Network Digitalization?
Functions Customer Benefits

 Power System Visualization Increased awareness
 Data Analytics Faster fault recovery process
 Fault Locating Better asset management
 Renewable Energy Source Control Manage decentralized generation
 Active Voltage Regulation Improved power quality, reduced losses
 Predictive Capacity Management Balancing energy demand and supply
within the network capability limits

6. Active Voltage Regulation with Grid Controller

6
Existing voltage control systems such as line drop compensation may no longer be suitable if
generation is connected to the feeder. Overvoltage situations have a negative impact on the
service life of electrical devices, cause higher technical losses and can trigger the feeder line /
transformer safeguards.

7. Active Voltage Regulation with Grid Controller

Introducing real-time measurement, VR, BESS, STATCOM or similar controllable elements one
can automate the distribution network management by introducing Grid Controller managing
the voltage regulator, P/Q compensation with battery storage, etc. based on current demand &
supply needs on the observed part of the distribution network.

12. Summary
Distribution Networks can be made Smart!
 Landis+Gyr’s ANM solution is based on field
proven, commercially available devices and
is validated by an independent service
provider
 ANM provides many benefits from better
quality of supply to optimizing current
assets usage
 The solution is able to predict mismatch
between supply and demand in the
selected region, automatically apply
corrective measures to the grid and
maximize its operational efficiency and
reliability as a result
