Abstract

This paper proposes a systematic approach to the design of a supervisory control scheme using a new method of the Hybrid Automata in Power Quality (HAPQ) improvement. In order to access a better power quality, a model is introduced for optimal controller uses and the general behavior of the power system is presented with Hybrid Automata (HA). The formalism of a hybrid system contains continuous dynamic and discrete switching behavior in a control and modeling framework. Hence, it can facilitate achieving a detailed description of the system while highlighting safety issues in the criteria of system design. This study uses a power system HA model as a discrete event system (DES) plant and controller. Discrete Event Systems (DESs) are utilized to examine HA models along with the presence and absence of disturbances and control features such as non-linear load, Static Compensator (STATCOM) and Filter. In order to examine the power quality and voltage stability, power quality indicators such as total harmonic distortion of voltage (THDv), eigenvalues, bus voltage and stability theory of switched systems are evaluated. The simulation results reveal the effective performance of the proposed supervisory controller HAPQ model to enhance power quality and stability in power systems.
