Robust decentralized controller design for UPFC using -synthesis

Investigation of UPFC performance under system uncertainties

“…In this system, the first area is a single generator, but the second area is aggregation of a large number of generators and performs like an infinite bus. The system data are completely presented in [7]. To study the performance of system over a wide range of loading conditions, three different cases as nominal, light and heavy loading are considered and listed in Table 1.…”

“…The detailed step-by-step procedure for computing of the controllers using structured singular value (l-based) technique is given in [16]. In [7] a systematic method to design UPFC controllers using mu-synthesis is presented. The robust synthesis problem is obtained in terms of the l-theory and the l-analysis.…”

“…In robust control approaches, the system uncertainties are incorporated in the controller design procedure and the controller is designed to operate under a wide range of uncertainties. Application of robust control methods for UPFC control has been reported in [7,8].…”

New approach for optimal UPFC placement using hybrid immune algorithm in electric power systems

“…According to the available literatures, the location of UPFC tends to be done empirically, if not arbitrarily, and the corresponding systematic investigation is not often enough [8]. The state-of-the-art UPFC analyses primarily focus on the application of stability control [8][9][10][11][12][13][14] in power systems.…”

Optimal Adaptive Controller Based on STATCOM and UPFC

“…A single-machine infinite bus system installed with UPFC is also considered as the second test case. The system data for the second test case are presented in [7]. The second test case is considered to evaluate the proposed MRAS tracking controller based on UPFC.…”
