In this paper, a detailed mathematical presentation of Photovoltaic (PV) generation system, as well as its simulation model based on MATLAB / Simulink is established first. Its inverter-based simplified models, i.e. the switching-function equivalent model and average model, are simulated and compared quantitatively from different aspects. Simulation results reveal that the switching-function equivalent...
A high-power photovoltaic (PV) system based on dual-stage topology of boost converter plus paralleled four-leg inverter is presented, which can perform as both grid-connected inverter and active power filter. The system not only can allow a wide range of input voltage from PV arrays, but also can compensate the nonlinear and unbalanced load current. This paper first presents the small-signal model...
A fast simulation platform dedicated to Micro Grid (MG) applications is proposed in the paper. The proposed simulation platform is essentially an additional library of the general simulation software PSCAD, which includes components and models in MG application. The content of the proposed simulation platform is introduced with 2 example models. A seamless control strategy is proposed to evaluate...
For high power grid connected devices with power quality compensation function, directly paralleled 3-phase 4-wire inverter is the most simple configuration to chose, but the zero sequence current is always a big problem that have to deal. This paper established the phase-leg averaging model of this type system, developed the dynamic model of zero sequence current, then indroduced a simple method...
