---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The changes in solar irradiation and source impedance impact on photovoltaic (PV) system control performance is examined. To acquire steady sinusoidal current tracking control for the grid-tied inverter, an internal-model-based undamped proportiona...

Within power systems, high-power pulsewidth-modulated ac–dc converters are used in flexible ac transmission systems controllers and for interfacing renewable energy sources to the grid. These converters traditionally employed PI controllers designed in the synchronous -frame with decoupling of and axes. Recently, stationary -frame proportional-resonant (PR) controllers have been proposed. Thoug...

Abstract Closed-loop DC Micro-Grid containing sustainable power sources, stockpiling components and burdens are introduced. The regulators for helping the control of mico-grid numerous in power-frameworks, yet most normally utilized one is PI regulator. Aside from there are, an entire bundle independent hybrid that can serve significantly better compared to microgrid framework relevance’s. syst...

In this paper, a symmetrical pole placement Method-based Unity Proportional Gain Resonant and Scheduled (PR-P) Controller is presented. The proposed PR-P controller resolved the issues that are tracking repeating control input signal with zero steady-state mitigating of 3rd order harmonic component injected into grid associated use PI for single-phase PV systems. Additionally, has overcome draw...

With the development of electric vehicles and More-Electric/All-Electric aircraft, high reliability is required in motor servo systems. The redundancy technique is one of the most effective methods to improve the reliability of motor servo systems. In this paper, the structure of dual-redundancy permanent magnet synchronous motor (DRPMSM) with weak thermal coupling and no electromagnetic coupli...

This paper proposed a control method for output and circulating currents of modular multilevel converter (MMC). The current are controlled with the help arm currents, which contain DC, fundamental frequency, double frequency components. is transformed into stationary reference frame (SRF) to isolate DC AC component conventional proportional resonant (PR) controller, while by controller. effecti...

Problems like windup or rollover arise in a PI controller working under saturation. Hence antiwindup schemes are necessary to minimize performance degradation. Similar situation may occur in a Proportional Resonant (PR) controller in the presence of a sustained error input. Several methods can be employed based on existing knowledge on PI controller to counter this problem. In this paper few su...

A solar photovoltaic distribution static compensator (SPV-DSTATCOM) under partial shading condition (PSC) is studied using a single-stage, 3-phase grid-connected mode. Under PSC, the performance of SPV-DSTATCOM and addressed issues such as active current sharing, reactive power control, harmonic elimination. Rejection DC offset with PSC an issue when conventional Proportional Resonant (PR) cont...
