With the increased penetration of distributed generation, maintaining voltages across distribution networks within statutory limits becomes challenging. To maintain the voltage within statutory limits with the variability of the distributed generation, a dynamic voltage control (DVC) mechanism should be implemented. Such voltage control also facilitates load control especially at peak load periods as the demand depends on the load busbar voltages to some extent. An electronically controlled series compensator based on smart distribution transformer was investigated to achieve the DVC in the low voltage distribution system. The controller design and the operation of the three-phase series compensator and its control are discussed. The proposed topology and control strategies are evaluated on a typical distribution network. From simulations, it was found that the smart distribution transformer can be controlled with less than two cycle response to obtain performance similar to a conventional transformer. Further, the DVC enhances the loadability of the smart distribution transformer.

This article investigates the problems of stochastic stabilization and control for a class of linear time-delay systems with Markovian jump parameters via output feedback. The jumping parameters are modelled as continuous-time, discrete-state Markov process. The delay factor is unknown and time-varying with a known bound. Concepts of weak and strong delay-dependent stochastic stability are introduced, and appropriate criteria applied to the jumping systems are developed. The control objective is to design an output-feedback controller such that stochastic stability and a prescribed H ∞ -like performance for a closed-loop system are guaranteed. We establish that the stability and stabilization problems for the time-delay Markovian jump systems can be essentially solved in terms of the solutions of a finite set of coupled linear matrix inequalities (LMIs). We show that in the case of weak delay-dependence, the controller is of arbitrary order and the associated gain matrices are computed implicitly. In the case of strong-weak coupling the controller is of full-order and explicit expressions are given for the associated gain matrices.
