A flexible asynchronous AC link (FASAL) system is a technology that interconnects two power networks operating at the same or different frequencies. The FASAL newly developed technology; therefore, it requires thorough investigation under unbalanced grid voltage conditions for better behavioral understanding and appropriate future controller design. In this paper, analyzed various symmetrical a...

Submodule (SM) capacitor voltage ripples in modular multilevel converters (MMCs) can be suppressed by harmonic injection strategy, which reduce the volume and cost of MMCs. The existing methods using dual strategy for hybrid MMCs only consider steady-state conditions. Harmonic strategies unbalanced grid conditions use single applied single-phase faults. To address above issues, this paper propo...

Wind energy is one of the fastest growing energies due to its feasible cost and environment friendly nature, where there no emission waste or greenhouse gases emission. systems should be connected electric utility avoid effects intermittent nature these sources. One main problems integration wind turbines unbalanced voltage grid. Many efforts have been made remedy grid with utility. This resear...

Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...

In this paper, an adaptive control strategy is proposed for the inverters of renewable energy source (RES) to simultaneously control the load voltage, grid current and the amount of instantaneous injected power to the grid in the presence of grid voltage distortions and nonlinearity of load current. In the proposed control strategy, the power quality of the local load can be settled based on th...

This paper presents a novel concept of utilizing the photo voltaic solar farm inverter as STATCOM(Static Compensator), named PV-STATCOM, in order to improve the voltage profile of the power system. The entire STATCOM is able to transmit either active or reactive power into the grid. This system is connected to a 14 BUS IEEE standard grid as a case study to simulate the performance of the system...
