An intelligent knowledge-based system (IKBS) for fault diagnosis and supply restoration in a vehicle is introduced. The system is based on techniques used successfully in the electrical power supply industry. The IKBS communicates with a simulator-store that remembers past faults. Scenarios are described to illustrate fault diagnosis and supply restoration. Manufacturers are replacing mechanica...

In order to investigate power system security and design appropriate control strategies, power systems can be conceptually classified into five operational states: Normal, Alert, Emergency, In Extremis, and Restorative. Various preventive and corrective control strategies have been studied to cope with power systems in the different operational states. Our approach primarily focuses on the corr...

This paper introduces the development and actual test results of the Korean Smart Distribution Management System (KSDMS). The KSDMS has been designed and developed to cope with the lack of interconnection capability of the Dispersed Energy Resource (DER), to provide standardization and compatibility, and to implement automatic processing of service restoration, in the existing Distribution Auto...

Electric power grids have been identified as critical infrastructures. They are increasingly dependent on Information and Communication Technologies (ICTs) for the operation and control of physical facilities. It can be envisioned that on top of the power infrastructure reside ICT layers that are coupled with the electric grids. As the ICT connectivity increases, so does the potential for cyber...

Fault diagnosis is a vital discussion in power systems restoration. Recently, much research endeavors have been done for fault section diagnosis of power systems by using several techniques, such as rule-based expert system, logic-based expert system, fuzzy relation based expert system, neural network, optimization techniques based approach, etc. They diagnose the fault from different ways. How...

one of the main problems in wind energy conversion system (wecs) is how to achieve maxim­u­m output power in different wind speeds. maximum methods for maximum power point tracking in wind energy conversion syst­e­ms require the knowledge of system characteristics and mechanic sensors. so, using these methods practically will follow with high price and an abundant difficulties. in this paper, n...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

For the application of Markov state space models in modelling substations and switching procedures, i.e. a supply restoration procedure, it is crucial to determine all parameters that influence the supply interruption duration. The Markov model is chosen due to a possibility to clearly model all procedures and states during disturbances, which result in the supply interruption, according to [1,...
