Application of Optimal Non-Linear TSK in Power System’s Load-Frequency Control with Production Limitation and Dead Band Govern

Regulating frequency of power systems, so called load-frequency control, is an important control issue in design and application of power systems. maximum performance of a power system requires a balance of produced power with total of used power and loss of energy. An event in the network brings about a change in the operation point of power system. Thus, there is a deviation in frequency and power appointed to each unit. Such deviations result in undesirable effects in the network.Load-frequency control, ,along with automatic production control, is one of the most important and challenging issues in design and use of power systems in order to obtain better performance and higher safety capabilitirs. In this paper, the idea of non-linar TSK fuzzy controller (NTSK) for two-area load-frequency system with considering limitation of production rate and dead band of governor has been proposed. We have used Cuckoo optimization algorithm for optimization of output coefficients of controller has been used. Next, TSK, Optiml TSK, and Optimal NTSK have been compared with each other according to RSM and ITSE criterions.
