Can multifunctional grid-connected photovoltaic systems improve power quality?
Potential solutions of power quality issues in modern power grid. The main aim of this work consists of proposing a new control strategy for multifunctional grid-connected photovoltaic systems (GCPVSs) to enhance the power quality at the point of common coupling (PCC) while considering the inverter-rated capacity.
What is a multifunctional PV system?
Recently, PV systems, in addition to their primary role, the injection of green power into the grid, are used for current harmonics filtering and compensation of reactive power, hence the name multifunctional PV systems.
What is a grid-connected multifunctional photovoltaic (PV) system?
In recent years, grid-connected multifunctional photovoltaic (PV) systems have proven to be highly efficient. This system integrates PV panels with a DC–DC boost converter (DC–DC–BC) and the electrical distribution grid (DEG). Linking the PV to the AC-DEG is accomplished through a three-level multifunctional voltage source inverter (MVSI).
Do grid-connected photovoltaic systems need a storage system?
Compared to off-grid systems, grid-connected photovoltaic systems (GCPVS) benefit from not requiring a storage system. In recent years, there has been a substantial increase in the integration of PV energy generation into the grid. However, integrating PV systems into the utility grid may cause some power quality issues [ 4 ].
What is a self-powered solar PV system?
The latter is a self-powered control technology that forces the SPV system to operate at MPP and thus utilize the maximum power obtainable under time-varying environmental conditions such as solar intensity, temperature, SPV module characteristics and module shading.
How does a solar PV generator work?
The solar PV generator supplies the load connected to the PCC and injects the surplus power into the utility grid. From 0 to 0.25s, the solar irradiance level (G) is kept at 1000 W/m 2. An Average active power of 50100 W is injected into the PCC, where 37670 W flows to the grid, and the load consumes the remaining one.
