Abstract

The frequency of a system is dependent on active power balance.

As frequency is a common factor throughout the system, a change in active power demand at one point is reflected throughout the system.

Because there are many generators supplying power into the system, some means must be provided to allocate change in demand to the generators.
– speed governor on each generating unit provides primary speed control function
– supplementary control originating at a central control center allocates generation.

In an interconnected system, with two or more independently controlled areas, the generation within each area has to be controlled so as to maintain scheduled power interchange.

The control of generation and frequency is commonly known as load frequency control (LFC) or automatic generation control (AGC).
