As mentioned in the previous section, equal sharing of the load as a percentage of nominal power is important since it enhances the capability of the power system to respond correctly to disturbances. Equal sharing is always possible when no turbines operate in the DLN mode since there are no constraints regarding output power other than operating within the minimum and maximum power output range. It is easy to meet these requirements since these points are at the extremes of the turbine output capability curves. When DLN operation is used, it is not possible to ensure equal loading among the turbines. As an example consider several non-DLN GTGs supplying the load. As shown in Figs. 2, 3 and 4, operation in 4% frequency droop will automatically ensure that load is shared equally as a percentage of the turbine nominal power. Should the plant load increase, the steady-state frequency will decrease and the PMS will send the same set point adjustments to all governors to increase the turbine outputs thus bringing the frequency back to its nominal value and ensuring correct load sharing at all times. This is true for all values of output power.
