Abstract To enhance the robustness and dynamic performance of a self-excited induction generator (SEIG) used in stand-alone wind energy system (WES), virtual flux oriented control (VFOC) based on nonlinear super-twisting sliding mode (STSMC) is adopted. STSMC to replace conventional proportional-integral-Fuzzy Logic Controller (PI-FLC) inner current loops. The combination proposed strategy with...

the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...

There is cause and effect relationship between increase in load due to increasing penetration of electric vehicles (EV) load that causes unbalanced conditions and affect the power quality such as voltage degradation and even damage the equipment if the system is not properly managed. This paper presents detailed review of energy supply and management in conjunction with load synchronization thr...

Abstract: Interest in DC microgrids is rapidly increasing along with the improvement of DC power technology because of its advantages. To support the integration process of DC microgrids with the existing AC utility grids, the form of hybrid AC/DC microgrids is considered for higher power conversion efficiency, lower component cost and better power quality. In the system, AC and DC portions are...

Several technologies are being used in distributed generation applications with variable degree of success. Among those are: wind turbines, small-scale hydropower plants, biomass, microturbines, photovoltaic arrays and fuel cells. In a fuel cell, the chemical energy incorporated in the fuel is converted directly to electricity and heat. Fuel cell technology is one of the most interesting energy...

Today's market of Power Amplifiers (PAs) offers both PAs stand-alone and PA modules (PA plus PA Controller, PAC, integrated in the same module). PA modules do not require an on-chip PAC but simply an Automatic Power Control (APC) able to shape the transmission (TX) burst for the PAC within the PA module. In order to maximize the flexibility of the on-chip PA's control system, the design of prog...
