<p>In order to achieve coordinated system-wide energy balancing in the control of bulk power transfer, the system known as the net interchange tieline bias control is modified so as to reduce inadvertent interchange while at the same time maintaining the average frequency of the interconnection as a whole at a predetermined value. This is accomplished by introducing into the control system of each area a coordinated modifying function corresponding with the quotient of the inadvertent interchange for each area measured over a span of time common to all areas divided by a constant representative of a common corrective time period for all areas, together with an additional modifying factor representative of the time integral of frequency deviation over a predetermined time period common to all areas multiplied by a bias factor common to all areas, such that a specific, unique and fixed relationship is maintained between the modifying function and the additional modifying factor.</p> |
