Modelling of Large-scale Grid-connected PV System with Reactive Power Control Methods

Abstract

Abstract This paper describes detailed scrutiny of the main components contained in the system. There is a DC-DC converter that extracts the maximum amount from the photovoltaic generator. The interface inverter was developed to transfer energy from the PV module into the grid with constant common dc voltage. A 90MW PV system with a 3-phased framework linked is planned and reviewed. This system is a high-fidelity exemplary with power control in the inverters, DC-DC converters, DC-AC inverters, and three-phase service grids used as components designed and formed mathematically as a reproduction model. The model contains various components such as the boost converter, the PV control modes, the inverter, and the framework utility. The essence of the reactive power generation in the PV inverter is represented. The components are modelled physically to generate high-fidelity simulation. Active and reactive power measurements are accurately taken and analysed. The study of the PQ controller is presented in the framework connection control of the system. The simulation results obtained in the modelling process show an effective power-controlled model.
