Abstract
This paper considers the problems of automatic correction of systematic error appearing in conventional Automatic Generation Control (AGC) regulators, due to the ignorance of power losses, normally existing on all inter-area tie-lines. This is achieved with modification of input signals on AGC area regulators (the Area Control Error, ACE) by introducing the tie-line losses, calculated by simple measurements of all area tie-line flows at both (sending and receiving) line ends. The paper presents the theoretical development of the idea and proposes the new, modified, but cheap AGC scheme, proven by simulation tests on the example of two-area inter-connection. The benefit of applying the proposed AGC regulators is the better system performance and less frequent need for the synchronous time and inadvertent interchange error corrections.
