“…These are the internal current control loop, which controls the grid current, and the external voltage control loop, which controls the DC bus voltage and reactive power. The harmonic elimination and dynamic response of the system are controlled by the current control loop and the power flow balance is controlled by the voltage control loop [27,28].…”

This study is recommended to develop a soft-switching control software infrastructure that enables more efficient and effective use of parallel resonant DC link circuits. The fact that the control technique can be easily applied to the soft switching circuit makes it important in this field. With this proposed study, lower voltage ripple and higher efficiency are obtained. To see the results of the technique and to study its effect, a study was carried out on a grid connected inverter. When the frequency changes between 5-15 kHz and 5-10 kW power is transmitted to the grid, the soft switching effect is studied and the efficiency is increased. A software model for calculating the power losses of semiconductor switches has also been established. Using this modeling approach, the power consumption is calculated in detail and the loss analysis is performed using catalog data of semiconductor switches. The accuracy of the obtained results was compared with another simulator. While the PRDCL inverter using the new proposed switching technique transmits 10 kW of power to the grid, the efficiency increased from 97.67% to 98.61% at a switching frequency of 5 kHz, from 96.82% to 98.58% at a switching frequency of 10 kHz, and from 95.61% to 98.55% at a switching frequency of 15 kHz.

“…The state-space averaging method has been used to obtain the equations of the inverter and then the dqO transformation is carried out to control the inverter in this reference system using PI controllers [27]. The Vd* reference value is defined to generate the desired 11 v,.·ms AC side voltage while V q * is maintained at O.…”

The increasing penetration level of the Renewable Energy Sources (R ES) and their variability can compromise the proper operation of an electrical grid. The microgrid is being analysed as a solution to obtain a high penetration of RES in a controlled way. Due to the stochastic nature of the RES, the Energy Storage Systems must be used to maintain the energy and power balance between generation and demand. The limits of the storage technologies that are nowadays available make it necessary to associate more than one storage technology creating a Hybrid Energy Storage System (HESS) in order to satisfy the specifica tions of a microgrid application: high energy autonomy, power capacity and fast response. This paper analyses by means of simulations and experimen tally the feasibility of a promising topology based on a Three Level Neutral Point Clamped (3LNPC) converter. The reduced power losses, improved THD and the fact of being an integrated solution are the advantages of this system. An islanding operation case study where a HESS formed by a SuperCapacitor (SC) and a Vanadium Redox Battery (VRB) supplies power to a resistive AC load that is suddenly reduced is analysed by means of simulations and experimentally. The simulation and experimental results prove the feasibility of the presented topology and of the control system to divide the power between the SC (fast power variations) and the VRB (low frequency part of the power).

This paper proposes strategies for a Wind Turbine with a Voltage Source Converter (VSC) in the case of a 200-300kW Permanent Magnet Synchronous Generator (PMSG). This control allows the synchronous generator to operate at an optimal speed. To show its effectiveness, a mathematical model of a variable speed wind energy conversion system is developed. The mathematical model is used to calculate the response of the wind energy conversion and to determine the maximum power operating point. This paper also provides the theoretical background of this method. Simulation of the system using Matlab / Simulink / SimPower System was performed to illustrate the advantages of this control strategy.
