Hi All,
I'm working on a study of a brownfield PowerStation that supplies a Plant Load and wants to connect to a utility Grid. Details as per below:
1. Import of MW from the grid only, zero MW export
2. Existing PMS(Power Management System) is ABB ENMC 800xA based
3. 4x GE Frame6 Gas Turbines, MarkVI Controller
4. At present, they operate as an island (Droop mode - ENMC as the secondary controller)
My question is:
1. What is the preferred operating mode/operating strategy for the Gas turbines(MW? Droop? or combination of both?) during grid connected mode? It's a fact that once the grid breaker is closed, it's the grid which controls the frequency.
