Automatic Generation Control Application for Transmission and Generation Centres

Recently, a new Emergency Control Centre for Albanian Transmission System Operator (TSO), which includes Supervisory control and data acquisition (SCADA) Automatic Generation (AGC) applications, has been commissioned. Nowadays, an AGC application is being prepared the biggest generation company in Croatia, as part of centre hydropower plants within western Croatia. Both these implementations use same application, presented this paper. Although TSO (GC) have many similarities, their main goals are different. must mainly regulate system’s frequency area’s active power interchange to desired values, using only engaged load-frequency (LFC). However, GC ensure that production each unit not LFC tracks its planned value, while also ensuring centre’s share respected. Albeit standalone both afore-mentioned it affiliated with SCADA from obtains all required input measurements indications delivers calculated setpoints. Additionally, pictures integrated into well, order simplify operation monitoring functionalities. controls six hydro LFC. West Croatia ten plants. In implementations, communication remote objects done IEC 60870-5-104 protocol, other centres ICCP protocol.
