A facile one‐pot hydrothermal method is provided for synthesis of the reduced graphene oxide‐cobalt tungstate (rGO@CoWO4) nanocomposites with the enhanced electrochemical performances for supercapacitors (SCs). The resulting nanocomposites are comprised of CoWO4 nanospheres that are well anchored on graphene sheets by in situ reducing. The BET‐specific surface area of CoWO4, rGO@CoWO4 nanocomposites are 101 and 167 m2 g−1, respectively. The electrochemical evaluations are carried out in a 1 M KOH solution as the electrolyte. The hybrid electrode shows excellent specific capacitance of 1145 F g−1 at a current density of 1 A g−1 with superior rate capability and satisfactory cycling stability (97.2% capacitance preserved after 10 000 cycles). The good electrochemical performance can be attributed to the increased electrical conductivity and the creation of new active sites due to the synergetic effect of rGO and CoWO4 nanospheres. Moreover, the cyclic stability tests demonstrat capacitance retention of about 97.2% after 10 000 cycles, suggesting the potential application of rGO@CoWO4 nanocomposites in energy storage devices. The asymmetric SCs assembled with rGO@CoWO4 and activated carbon exhibit high energy density (39.1 Wh kg−1) and power density (631.2 W kg−1 at 1 A g−1), with remarkable cycle life (96.7% over 10 000 cycles) while still maintaining 24.5 Wh kg−1 at an even higher power density of 5098 W kg−1. The above results indicate that the hybrid rGO@CoWO4 electrodes synthesized by this approach would be a promising candidate for practical application of high‐performance SCs.

As grid transmission difficulties is increased in rural areas so the standalone PV system has become a better option to power smaller rural areas. The main contribution of standalone PV system is the energy storage system (ESS) which reduces the intermittency effects at the solar farm. Though, batteries are the commonly used ESS, they are susceptible to low lifetime with increased maintenance cost. In such case, supercapacitors are considered for the better alternative. The role of capacitors in the standalone PV system have been investigated in this paper using Matlab/Simulink and hardware. It is observed that the supercapacitors help to improve the battery lifecycle.

This paper proposes adaptive Maximum Power Point Tracking (MPPT) controller for Permanent Magnet Synchronous Generator (PMSG) wind turbine and direct power control for grid side inverter for transformer less integration of wind energy. PMSG wind turbine with two back to back voltage source converters are considered more efficient, used to make real and reactive power control. The optimal control strategy has introduced for integrated control of PMSG Maximum Power Extraction, DC link voltage control and grid voltage support controls. Simulation model using MATLAB Simulink has developed to investigate the performance of proposed control techniques for PMSG wind turbine steady and variable wind conditions. This paper shows that the direct driven grid connected PMSG system has excellent performances and confirms the feasibility of the proposed techniques. While the wind turbine market continues to be dominated by conventional gear-driven wind turbine systems, the direct drive is attracting attention. PM machines are more attractive and superior with higher efficiency and energy yield, higher reliability, and power-to-weight ratio compared with electricity-excited machines.

Thispaper deals with the analysis, modeling and control system for permanent magnet synchronous generator (PMSG) based wind turbine connected to the grid. A wind energy conversion using DC-DC Buck- Boost Converter for permanent magnet synchronous generator (PMSG) based variable speed wind energy conversion system (WECS) has been proposed which is integrated with grid using five-level diode clamped multilevel (DCMLI) inverter. In this work the instantaneous values of input side current and voltage of DC-DC buck-boost converter are utilized for implementing the PID controller. The proposed work is verified by the simulation in Powersim.
