Increased electric energy consumption in recent years, associated economic problems, reduced reliability and increased power losses in electric networks. One of the main solutions in smart grids to overcome the mentioned problems is demand response programs. In demand response programs, operators apply time-varying tariffs to consumers, and convince them to change their consumption pattern. Amo...

Arch-shaped microelectromechanical systems (MEMS) have been used as mechanical memories, micro-relays, micro-valves, optical switches and digital micro-mirrors. A bi-stable structure, such as an arch, is characterized by a multivalued load deflection curve. Here we study the symmetry breaking, the snap-through instability and the pull-in instability of a bi-stable arch-shaped MEMS under static ...

The scheduled electric vehicle (EV) charging flexibility has great potential in supporting the operation of power systems, yet achieving such benefits is challenged by uncertain and user-dependent nature EV behavior. Existing research primarily focuses on modeling arrival battery status rarely discusses uncertainty departure. In this paper, we investigate scheduling strategy to support load fla...

the nonlocal nonlinear buckling of a double layer graphene sheet (dlgs) covered by zinc oxide (zno) piezoelectric layers is investigated in this study. the surrounding circumstances of the system are considered as a pasternak foundation including spring constants and a shear layer. graphene sheets are subjected to longitudinal magnetic field and biaxial forces. on the other hand, the zno piezoe...

The article investigates models and methods of electric load forecasting. It is shown that the following power consumption control are currently known: instantaneous norm; at ideal rate; management on forecast value; with use average a moving time interval ("moving window" method). it better to focus those based study estimates, which source information for decisions. main requirements real-tim...

Integrating electric vehicle (EV) charging infrastructures into the utility grids requires solutions for coordinated of EVs. Load management systems aim at computing schedules vehicles based on predetermined objectives. Contributions EVs predominantly assume that or stations are controllable entities in load systems. However, practice, may consist and uncontrollable entities. This paper propose...

Microgrids are nowadays used to produce electric energy with more efficiency and advantage. However, the use of microgrids presents some challenges. One of the main problems of the microgrids widely used in electrical power systems is the control of voltage, frequency and load sharing balance among inverter- based distributed generators (DGs) in islanded mode. Droop method performance degra...
