A grid-connected inverter’s stability is easily influenced by the system’s internal and external characteristics, especially when inverter connected to grid an LCL filter, which complicates system design operating conditions. To handle problem of disturbance in high-order inverter, a linear active rejection control (LADRC) strategy based on LCCL (which divides capacitor filter into two halves s...

The transformerless PV inverters are the major functional units of modern grid-connected PV energy production systems. In this paper, a new optimization technique is presented for the calculation of the optimal types and values of the components comprising a transformerless PV inverter, such that the PV inverter Levelized Cost Of the generated Electricity (LCOE) is minimized. The proposed metho...

Renewable energy, such as solar energy, is desirable for power generation due to their unlimited existence and environmental friendly nature. Reforming of the electricity sector along with various renewable energy promotion policies has increased the importance of small grid connected photovoltaic (PV) systems utilizing single stage single phase inverters. This paper proposes a single-stage inv...

This paper presents a single-phase five-level photovoltaic (PV) inverter topology for grid-connected PV systems with a novel pulse width-modulated (PWM) control scheme. Two reference signals identical to each other with an offset equivalent to the amplitude of the triangular carrier signal were used to generate PWM signals for the switches. The inverter offers much less total harmonic distortio...
