Design and control of Proportional-Resonant controller based Photovoltaic power conditioning system

2009 IEEE Energy Conversion Congress and Exposition, 2009
This paper presents a current control technique for a single-phase grid-connected DC/AC inverter which is used in Photovoltaic power conditioning system (PV PCS). A Proportional - Resonant (PR) controller is used for replacing the conventional Proportional - Integral (PI) controller in this system. By comparison with the conventional PI control method,

Control of a Proportional Resonant Current Controller Based Photovoltaic Power System

2019
This paper presents a power factor control of PV system connected to the grid. A Proportional-Resonant (PR) controller is used for replacing the conventional Proportional-Integral (PI) controller in this system. By comparison with the conventional PI control method, the PR control can introduce an infinite gain at the fundamental frequency and hence ...

Performance improvement of dynamic voltage restorer using proportional - Resonant controller

2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY, 2014
The tripping of drive systems in process industries are caused due to voltage sag or swell, which results in heavy economic losses. As a solution to this, DVR is reported. By using PI-controller for the control of DVR, a noticeable steady state error is found.

Proportional resonant control technique for grid interfacing of multilevel inverter

2018 International Conference on Power, Instrumentation, Control and Computing (PICC), 2018
This paper brings study and practical implementation of proportional resonant (PR) control for grid synchronization using single phase multilevel (five-level) Reversing voltage (RV) topology. The PR-control is a low complexity grid synchronization scheme, which generates active and reactive power components, and so that there is independent control of ...

Optimized tuning method of stationary frame Proportional Resonant current controllers

2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014
This paper presents an optimized tuning method of Proportional Resonant (PR) current controllers implemented in the stationary frame. The approach consists of defining three operation regions based on behavior of the closed loop poles, and of determining simplified tracking and disturbance transfer functions for each of these regions.

Multi-Frequency Proportional-Resonant Control for Wave Power Generation System

Advanced Materials Research, 2013
A grid voltage vector oriented proportional resonant (PR) control strategy is applied to the grid current control of the float-type wave power generation system. Compared with the conventional double closed-loop proportional integral (PI) control method, the proposed multi-frequency PR control method can realize zero steady-state error in AC input ...

Study on Proportional Resonant control strategy of single-phase SVG

2012 IEEE International Symposium on Industrial Electronics, 2012
Single-phase Static Var Generator (SVG) is widely used in fields like electrified railway and Distribution Generation (DG) etc. However, it has special requirements and difficulties, e.g. a single-phase SVG is not easy to achieve satisfactory performance of tracking the AC reference comparing with the three-phase one.

Proportional resonant controller for a 27-level asymmetric multilevel STATCOM

2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 2017
In this paper a 27-Level Asymmetric Multilevel STATic COMpensator is presented aimed to compensate reactive power. The STATCOM is controlled with a master-slave approach, where the master loop is responsible to regulate the DC voltage using a Proportional-Integral controller, while the inner loop is in charge to track the reference currents through a ...
