Flexible Alternating Current Transmission System (FACTS) for Reactive Power Compensation for the Kazakhstan Electricity Grid Operating Center (KEGOC)

Currently, power system of Kazakhstan faces voltage issues in its Northern part, which are the consequence of undesired transit flows over its transmission grid. In order to control voltages and power flows over its transmission system, transmission system operator of Kazakhstan – KEGOC, considers installing appropriate FACTS devices in certain locations in the network. The overall project comprises of three tasks:

• Task 1: Proposal of locations and types of FACTS devices in order to resolve current voltage and transit issues.
• Task 2: Detail analysis of current and planned systems states and proposal for solutions of identified issues through installation of additional FACTS devices
• Task 3: Definition of FACTS installation roadmap with cost estimates

All analyses were conducted by using the DIgSILENT PowerFactory software.

Type of services provided:

• Load flow calculation and voltage profile assessment
• Security N-1 analysis
• Short circuit analysis
• Transient stability analysis
• Development of FACTS devices’ dynamic models
