SUMMARYWith the fast-paced changing technologies in the power industry, new power references addressing new technologies are coming to the market. So there is an urgent need to keep track of international experiences and activities taking place in the field of modern power system restoration problem. This paper gives a bibliographic survey, mathematical formulations, and general background of research and developments in the field of restoration problem for past 35 years, based on more than 150 published articles. The collected literature has been divided into many sections, so that new researchers do not face any difficulty in carrying out research in the area of next-generation restoration problem under any environment.

“…The existing central-based distribution automation systems have significant contribution in improving the power supply reliability for distribution system with radial structure [1][2]. However, because it monitors system status, collects operation data and executes fault processing procedure when any fault occur, based on polling method under oneway communication, it can not be applied directly to a smart grid distribution system with bi-directional communication capability due to the reasons described below.…”

-This paper proposes a new fault isolation methodology for a smart protective device which plays an agent role on the smart grid distribution system with the distributed generation. It, by itself, determines accurately whether its protection zone is fault or not, identifies the fault zone and separates the fault zone through the exchange of fault information such as the current information and the voltage information with other protective devices using bi-directional communication capabilities on the smart grid distribution system. The heuristic rules are obtained from the structure and electrical characteristics determined according to the location of the fault and DG (Distributed Generation) when faults such as single-phase ground fault, phase-to-phase short fault and three-phase short fault occur on the smart grid distribution system with DG.

“…For instance, traditional load shedding has been applied in where it sheds a fixed amount load with decreasing frequency [1,2]. Some methods proposed a load curtailment procedure where it considers violation vector with current capacity and also voltage drops [3]. HARRISON presented a control method to prevent voltage instability using a dynamic model of load shedding [1].…”

Abstract:In this paper, the computerized controller for studying load shedding has been designed and implemented. This controller is designed based on the problem of minimizing load shedding during emergency conditions. The studied problem is formulated as a nonlinear static optimization problem subject to operational and equipment constraints. Suitable adjustments of control of generation rescheduling and control of phase shifting transformers before load shedding is determined and recommended. SUMT, solution algorithm adopting sequential unconstrained minimization technique is given. Results of application of the proposed technique to a 5 and 20-node network are presented. An overload relief policy is proposed to minimize load shedding.the proposed computerized technique have been presented in this paper.Applications to be IEEE -5 and 20 bus system are presented to validate the applicability of the proposed technique to any system of any size.
