This paper describes an specific approach to resolving problem of Load Frequency (LF) control in power system of Montenegro (Serbia and Montenegro). The complete LF controller was developed, coded and implemented on the single PC computer "from zero" by the Company's staff in an fast, feasible and cost-effective manner. Its extremely high "in-field" efficiency was achieved by: compact design of the controller, implementing algorithm for efficient control error filtering, algorithm for minimizing of regulating units movement, as well as feed-back algorithm for permanent adjustment of the tie-lines power measurements. Details on these algorithms are given. The official field results for the six months exploitation have confirmed the top regulating success in the Second UCTE Synchronous Zone. The Electric Power Company of Montenegro was recently subjected to enacting of new Energy Law, and promoting free electricity market. So, the additional modifications were made at the AGC controller to meet the requirements of deregulation processes. Thus, AGC system keeps track of momentary active power imbalance, detects it, corrects it and communicates an adequate amount of BES (Balance Energy Service) power, on the 15-minutes basis, to the real-time part of MOS (Market Operating System), where it will be allocated to RTM (Real Time Market) balancing resources.
