Download: UPFC PLUS - Enhancing transmission grid stability and reliability through dynamic load flow control

To effectively manage the transmission system and provide the stability and resilience required means operators must better utilise existing assets. This can be achieved by employing a dynamic load flow management solution such as UPFC (unified power flow controller) which is extremely faster to react and can manage both series and parallel compensation to keep lines within the n-1 criterion and the electricity flowing. The UPFC can balance load flow in the AC grid, rapidly bypass overloaded line sections, provide reactive power and dynamic voltage control, and utilise assets to physical limits without the need for safety margins.
