As the single-phase inverter in a grid-tied PV system receives varying DC voltage from PV modules, the PQ-DBHCC strategy is deployed to regulate the ac output voltage along with its capability to deliver the maximum power during onload conditions.
Investigated PQ control using FCS-MPC approach Usually, the grid-tied inverter operates most of the time in “normal mode,” where the DER normally injects to the grid only active power with nil reactive power (unity PF operation). However, when a fault occurs “LVRT mode,” the grid voltage is reduced “voltage sag.”
In photovoltaic (PV) applications, single-phase inverters are commonly used for DC to AC power conversion interfaces. The most critical factor in evaluating the performance and quality of the inverter is to examine the output voltage and current.
Abstract: This paper presents a flexible control technique of active and reactive power for single phase grid-tied photovoltaic inverter, supplied from PV array, based on quarter cycle phase delay methodology to generate the fictitious quadrature signal in order to emulate the PQ theory of three-phase systems.
Conclusions In the present paper, an FCS-MPC approach has been adopted to control the operation of single-phase grid-connected inverter fed from a pv array as a renewable resource and a battery bank as an energy storage element. The control scheme provides LVRT capability of the grid-connected inverter following the grid code standards.
The inverter is connected to the PV array to obtain a DC active power, P so that the system would have a close-loop feedback from the PV to Inverter and then to the Grid. This paper proposes a combination of hysteresis and PQ theory to create the gating pulses for the inverter and to provide synchronization between the PV and grid parameters.
In single-phase systems, successful application of direct PQ control depends on accurately creating the fictitious orthogonal components of grid current and voltage required for instantaneous power computations.
