This paper presents the operation of a grid-tied photovoltaic power generator considering a two stages configuration for active power injection. A Neutral Point Clamped Inverter (NPC Inverter) was used for the DC-AC conversion and a DC-DC Boost converter complemented the system configuration. The control system includes the following loops: a maximum power point tracking algorithm, a DC bus voltage...
This paper presents an analysis of two algorithms used to control the active and reactive powers in three phase inverters for grid-tied photovoltaic systems under unbalanced voltages in the Point of Common Coupling (PCC). The algorithms are focused on injecting balanced currents to the grid despite the voltage unbalances. The analysed algorithms are composed of two control loops: the reference signal...
This paper presents a comparative analysis between different control techniques for voltage source inverters (VSI), based on shunt active power filter. The main purpose is to study the behaviour of each technique for a given reference current. In addition, some simulations are presented in ATP. The reference signals tracking for different current control techniques and different converter topologies...
