摘要：This paper presents a control mechanism for Automatic Generation Control of multi generating interconnected power system. This control technique organise the excellent relationship between the electric load forecasting & Economic Load Dispatch for interconnected power system. The main component of LFC is to monitor the frequency nearly at constant standard value (50 Hz in India) & to regulate the net balance interchanged tie-line power flow between the different control areas within the prescribed limit. Since, electrical load is always fluctuating in nature & due to slow response of Area Control Error (ACE), needs some other means to overcome this limits& this leading to the forecasting technique to be incorporated with the Economic Load Dispatch for improved dynamic response of the power system. Load prediction technique is incorporated by Kalman filter recursive algorithm & then this bank of load is interpolated at a regular interval of 5 – minutes & these conceptscalled as “a very short-term load forecasting”. Total forecasted demanded electric load is distributed among the different generating unit via participation factors in context with the concepts of Economic Load Dispatch & Generation allocation. Results & Discussion section of this paper support this control technique wisely for the given simulated interconnected power system.
