Centralized Optimal Control for a Multimachine Power System Stability Improvement Using Wave Variables
نویسنده
چکیده
this paper introduces the application of wave variable method in reducing the effect of delay during the transmission of control signals via large distances in a multimachine power system. Fast response and pure control signals applied to a power system have great importance in control process. At first we design a centralized optimal control considering no transport delay and then we compare them to the one considering this effect in order to demonstrate the deteriorating effect of transmission delay. Then we apply the wave variable method and it is shown that performance of centralized optimal controller is improved. KeywordsCentralized optimal control, delay; multimachine; wave variable

متن کاملA New Excitation Control for Multimachine Power Systems I: Decentralized Nonlinear Adaptive Control Design and Stability Analysis
In this paper a new excitation control scheme that improves the transient stability of multimachine power systems is proposed. To this end the backstepping technique is used to transform the system to a suitable partially linear form. On this system, a combination of both feedback linearization and adaptive control techniques are used to confront the nonlinearities. As shown in the paper, the r...

In this paper a new excitation control is developed for multimachine power systems that improves the transient stability. The design is based on the sliding mode technique which is applied on an equivalent model of the system obtained by using the backstepping technique. However, the conventional “sign” method with constant gains is replaced by the boundary layer sliding mode technique with tim...
