نویسندگان
چکیده
Abstract Aiming at the harmonic resonance problem of photovoltaic inverter cluster system when it is incorporated into weak power grid, an active damper frequency division control method proposed to suppress resonance. Firstly, voltage signal measured by transformer separated according frequency, and then conductance value band controlled respectively voltage. Finally, output current feedback generalized integral PI controller, so as realize impedance remolding system. This can adjust virtual in different adaptively voltage, more effectively. The simulation results Matlab/Simulink demonstrate correctness effectiveness method.

Islanding Detection for Photovoltaic Inverters Using the Sandia Frequency Shift Method
The connection of inverters for distributed generation photovoltaic systems to the distribution network creates situations of risk to the loads that are connected to the point of common coupling (PCC) and personals who maintain the power grid. A risk that should be avoided is the supply of electricity, by one or more inverters, to the distribution network after disconnecting the main power grid...
متن کاملPower control flexibilities for grid-connected multi-functional photovoltaic inverters
This study explores the integration issues of next-generation high-penetration photovoltaic (PV) systems, where the grid is becoming more decentralised and vulnerable. In that case, the PV systems are expected to be more controllable with higher efficiency and reliability. Provision of ancillary and intelligent services, such as fault ride-through and reactive power compensation, is the key to ...
متن کاملVoltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control
Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent. This controller is used in a double loop structure including an inner current loop and oute...
متن کاملUptime Improvements for Photovoltaic Power Inverters
For optimum performance, the expansion of solar energy installations requires a robust and reliable infrastructure of panels, inverters and system control. Because of the geographically distributed and sometimes remote deployment of these solar power installations, reliability and performance is paramount to wider-scale adoption of these systems. Thus, it is very important to monitor the perfor...
متن کاملSemi-active H∞/LPV control for an industrial hydraulic damper
In this paper, a new control strategy is developed to improve comfort and roadholding of a ground vehicle equipped with an industrial damper. This damper can be controlled by means of a small servomechanism which adjusts the damping rate. The main controller is a linear parameter varying (LPV ) static state-feedback controller synthesized in the H∞/LPV framework to compute the required damping ...
