Some fundamental structural characteristics of large-scale power systems are analyzed in the paper. Firstly, the large-scale power system is decomposed into various hierarchical levels: the main system, subsystems, sub-subsystems, down to its basic components. The proposed decomposition method is suitable for arbitrary system topology, and the relations among various decomposed hierarchical lev...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility service companies the opportunity to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. The AMR system consists of thre...

As large-scale wind power has been and will be integrated into power grid, traditional Active Power Dispatch and Control (APDC) system has encountered new challenges. In this paper, the active power dispatch mode of interconnected power grids which is suitable for the large-scale integration of wind power is analyzed firstly. Secondly, it is pointed out that traditional decentralized balance co...

Many real-world systems are governed by the timedependent, nonlinear differential equations. Dynamics of an electrical system are also best described using the very equations. Being one of the preferred machines when using advanced control algorithms for electric drives, DC motor has been selected for position tracking. Defining dynamic equations of the motor derived from the theory of nonlinea...
