Optimal voltage regulator placement

Optimal voltage regulator placement module

Robust calculations

Using Eaton's CYME Load Flow Analysis, the module provides a weighted-objective optimization technique that allows for users to:

• Flatten voltage profile at a specified target voltage and to minimize abnormal conditions
• Minimize active power losses

The Optimal Voltage Regulator Placement module provides two algorithms:

• Sequential Search – find the optimal location for one regulator at a time
• Iterative Search – An exhaustive analysis which evaluates each possible location to give the overall best solution

Features

To make the analysis more comprehensive, multiple user-defined options are available:

• Install single or multiple regulators
• Install different types of regulators
• Specify search distance for the addition of a regulator
• Include or ignore existing regulators
• Evaluate locations downstream to feeders, specific sections or specific nodes
• Define voltage regulator control settings
• Set user-defined constraints such as under- or over-voltage limit margin, maximum buck and boost limits, ignore sections or laterals

The module is centered on robust algorithms and used-defined criteria to provide users with results that are both trust-worthy and operationally acceptable.

Customization of the reports is possible to allow:

• The results display of the optimal solution, of all tested solutions or of a maximum number of solutions
• Show active power losses for each result displayed
• Report abnormal voltages count for each result displayed

Charts and display on the one-line diagram help visualize the results.

The user can display the voltage profile chart of the initial network and that of the best solution to see whether voltage regulation is achieved as expected.

The one-line diagram can be color-coded to highlight evaluated sections. The voltage regulator suggested by the module can be applied to the network via buttons in the report.
