this paper argues for a broader emphasis on sustainable security and smart power, for examining both opportunities as well as threats to security. sustainable security is a new concept in the security studies. deep attention to all possible threats against human life is necessary for continuation of security in a sustainable and dynamic base. this aim can be achieved in a highest level by mergi...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. according to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...

this study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. however due to unpredictable nature...

Recently many significant improvements have been done in traditionally power system. But still a lot of work is needed in traditional power system to mend many challenges. We propose formal method based on subnet model for smart power system. Formal method is mathematics based technique that is used to develop, specify and verify model in a systematic manner. It involve components i.e., power p...

Smart power grid is the future transformation of the current power systems into controlled two-way power flow networks. Smart grid allows the interactive service between customers and grid operators and permits fully integration of distributed and renewable energy resources into the electrical power system. The main objectives of the smart grid are to increase the efficiency, reliability and op...

This research deals with the Non-Isolated Bidirectional Dc-Dc Converter (NBDC) control unit development for a smart power supply system using personal residential Photovoltaic-Power Conditioning Subsystem (PV-PCS), the results of circuits evaluation, and isolated PV-PCS operation connected battery storage (Electric vehicle storage etc.). The smart power supply system using the existing resident...
