In an interconnected power system, all the generators must run at an appropriate capacity to meet the demand in power. Loss of synchronism between the generators and/or too much frequency fluctuations may cause protective equipment to trip. Load frequency control (LFC) is necessary to balance the power generation and the load, by monitoring frequency and power changes between interconnected power...
