Demand of energy is more sensible now because of population growth and economic growth of countries. In order to increase of energy consumption around the world and environment pollution, attention to the renewable energy such as solar energy is inevitable. Building-integrated photovoltaic (BIPV) electric power systems not only produce electricity, they are also part of the building. For exam...

Intensified industrialization in developing countries has recently resulted in huge electric power demand growth; however, electricity generation in these countries is still heavily reliant on inefficient and traditional non-renewable technologies. In this paper, we develop an integrated game-theoretic model for effective power systems planning thorough balancing between supply and demand for e...

A platform implemented with Digital Signal Controllers (DSCs) developed for real time studies of the dynamic behavior of the air-gapped current transformers (CTs) used in power grid protection and measurement systems is presented. The implemented algorithms simulate the fault current in an electric power system as well as the transient response of the current transformer. It is also presented a...

Power system blackouts have become a serious problem for electric utilities especially in recent years. Different forms of system instability have emerged in recent blackouts, such as voltage instability and frequency instability. To counteract each form of system instability, special algorithms have been designed in the protection system, e.g. Under Frequency Load Shedding (UFLS) and Under Vol...

This research embodies the design, construction and simulation of a feeder pillar (415VAC) with over-current, overload and earth-fault protection with the aid of a phase sequence relay, contactor, earth-leakage circuit breaker and three-phase overload relay. The analog voltmeters in the various bus-bars (red, yellow and blue phases) in a conventional feeder pillar is replaced with a digital pan...

Using a top-down design methodology, two levels of hybrid electric vehicle power system are presented in the paper. At the highest abstraction level, a behavior modeling method is used to develop models for 3-phase AC/DC converter and brushless DC motor controller, which reduce the simulation time without compromise of accuracy. At the second level of design, six diodes along with delta-delta a...

37 Security Impact on e-ATM Windows Communication Foundation Services using Certificate based Authentication and Protection: An implementation of Message Level Security based on .NET Technique; Subhash Medhi, Loktak Power Station, National Hydro Electric Power Corporation Ltd., Loktak, India Abhijit Bora, Department of Electronics & Communication Technology, Gauhati University, Guwahati, India ...

Three-dimensional numerical simulations are performed to investigate the effects of pressure drop across the turbine and solar radiance on the performance of a solar chimney power plant (SCPP). The SCPP system expected to provide electric power to a city is located in southern region of Iran (city of Lamerd, Fars province). Its dimensions are similar to the Manzanares prototype (built in Spain,...

This project envisions a fundamental shift in the approach to the electric power infrastructure with both a broadening of the electric grid to consider overall end energy use and a “flattening” of the control structure at all levels of the power grid the traditional control strategies. In particular, the research of the Northeastern/Tufts team concentrates on wide-area monitoring and estimation...
