Modelling, Analysis, And Integrated Control Of Electrical Complexes Under Variable Operating And Load Conditions

Abstract

The electrical complexes of modern industrial and power systems generally operate under variable conditions of dynamic load variation with the increased utilization of power electronic devices and renewable energy resources. The impact of these conditions on the stability of electrical complexes is considerable. Therefore, the traditional fixed-point design method is no longer applicable. In the context of the above, a comprehensive framework of modelling and analysis of electrical complexes under variable conditions of dynamic load variation is proposed. In this context, unified mathematical models of electrical complexes and interconnected systems in the state space have been proposed. The methods for the evaluation of dynamic performance, stability, and robustness under parameter uncertainties are described. Moreover, integrated control strategies, which use a combination of classical control, optimal control, and adaptive control, can be employed to achieve integrated control as well as robustness. The above-discussed methods have shown promise for enhancing voltage regulation, dynamic performance, and efficiency, and they can be considered a robust tool for developing reliable and intelligent electric complexes.
