Power system stabilizers design using optimal reduced order models. II. Design

Abstract

These two companion papers a d d r e s s t h e design of Power System Stabilizers using an optimal reduced o r d e r model whose s t a t e variables a r e torque angles and speeds.The reduced o r d e r model retains t h e modes t h a t mostly affect these variables.A steady s t a t e e r r o r criterion is utilized to identify t h e modes that need to be retained. The effect of t h e other modes is compensated for through optimization of t h e steady s t a t e e r r o r criterion. The reduced o r d e r model i s used to design a linear feedback controller that takes into account the realities and constraints of electric power systems.Effectiveness of t h i s controller i s evaluated and examples, one machine-infinite b u s system and a multimachine system, a r e given to illustrate t h e advantages and effectiveness of t h e proposed approach.

A new approach using optimization for tuning parameters of power system stabilizers

“…(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26) in this paper. This package uses Han-Powell Method (recursive quadratic programing) [22] to obtain a local optimal solution (rather than a suboptimal solution).…”

“…(3) Order reduction and pole assignment were used to tune the PSS parameters in [15,16]; however, the order reduction sometimes will lead to inaccurate solutions [16]. Other pole assignment methods were proposed in [17,18].…”

Optimal tunning of lead-lag and fuzzy logic power system stabilizers using particle swarm optimization

“…Many random search methods, such as genetic algorithm (GA) and simulated annealing (SA) (Feliachi et al, 1988;Xia & Heydt, 1983 optimal solution in problem space and they have been applied to the problem of PSS design (Abe & DOI, 1983;Arredondo, 1997;Do Bmfim et al, 2000).…”

Application of D-K Iteration Technique Based on H∞ Robust Control Theory for Power System Stabilizer Design

“…This D-K iteration method of controller design, which combines H∞ synthesis that ensure robustness and µ-analysis that takes care of parametric uncertainties, and yields a good performance of the robust controller has been applied for the Power System Stabilizer (PSS) design [10], [11]. PSS contributes significantly in mitigating the spontaneous low frequency oscillations in the range between 0.2 to 3 Hz, which power systems experiences, by generating supplementary control signal.…”
