Load frequency control
Abstract: frequency control is one of the most profitable auxiliary services for the power systems through maintaining short-term balance of energy and frequency. Intro two main variables that change during transient power load are: area frequency and tie line power interchange the concept of load frequency control (lfc) is directly related to the aforementioned variables since the task is to minimize this variation. The primary reason for accurate frequency control is to allow the flow of alternating current power from multiple generators through the network to be controlled the trend in system frequency is a measure of mismatch between demand and generation, and so is a necessary parameter for load control in. (12) the operation of load-frequency control, as a core tso responsibility, shall be defined at the level of the lfc area in form of automatic and manual control. Frequency is greatly depends on activepower and the voltage greatly depends on the reactive power the active power control and the frequency control are generally known as the automatic load frequency control.
Iv abstract in an interconnected power system, if a load demand changes randomly, both frequency and tie line power varies the main aim of load frequency control is to minimise the transient variations.

Thanks here's what i think have understood so far say a generator rated at 100mva is delivering its rated power at 50hz frequency and governor droop is 5% (which means no load frequency will be 105%)the speed changer setting is such that ithe machine will deliver 100mw at 50hz.
