Development of a MATLAB/Simulink Model of a Single-Phase Grid-Connected Photovoltaic System

Abstract

Because of their deployment in dispersed locations on the lowest voltage portions of the grid, photovoltaic (PV) systems pose unique challenges to power system engineers. Computer models that accurately simulate the relevant behavior of PV systems would thus be of high value. However, most of today's models either do not accurately model the dynamics of the maximum power point trackers (MPPTs) or anti-islanding algorithms, or they involve excessive computational overhead for this application. To address this need, a MATLAB/Simulink model of a single-phase grid-connected PV inverter has been developed and experimentally tested. The development of the PV array model, the integration of the MPPT with an averaged model of the power electronics, and the Simulink implementation are described. It is experimentally demonstrated that the model works well in predicting the general behaviors of single-phase grid-connected PV systems. This paper concludes with a discussion of the need for a full gradient-based MPPT model, as opposed to a commonly used simplified MPPT model.

Seguimiento de trayectorias tridimensionales de un quadrotor mediante control PVA

“…Este software es ampliamente empleado en el modelado de dispositivos eléctricos (Le-Huy, 2001), electrónicos (Karden et al, 2002) y (Ropp and González, 2009) y mecánicos (Hajjaji and Ouladsine, 2001), así como en control, tanto en diseño y simulación (Altas and Sharaf, 2007), como en control en tiempo real (Pivonka and Miksánek, 2007). Se utiliza también en la implementación de sensores o predictores (Qiu et al, 2004).…”

Modeling and Simulation for an 8 kW Three-Phase Grid-Connected Photo-Voltaic Power System

“…However, it is an offgrid PV system. A 10 kW PV system is presented in [14], but the system is only for a single-phase grid-tied PV system.…”

Modelling of embedded PV generation in distribution networks

“…At best, some developed models are insufficiently validated. Hence, there is a need to develop and deploy valid and generic power flow and stability models for interconnection studies and verify the model by conducting hardware experiments to ensure their usefulness for power system operators and planners [1,2]. Power system planners require models of distributed PV generation in order to run simulations on the power network and identify whether it can withstand certain contingency events [3], in other words the development of models is vital to understand the impact that distributed PV generation has on the stability and operation of the grid [4].…”
