Multifunctional solar power supply

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.

How is a SunPower PV array modeled?

For this model, the PV arrays are modeled with SunPower SPR-415E-WHT-D modules. The IV curve and Power versus Current curves for the 1.5-MW SunPower array are shown in Fig. 7. 2.3. Power converters modeling and filter design

How does a solar PV system work?

The system has a three-phase utility grid connected to a nonlinear load and a solar PV power generation system. The PV array is integrated into the grid via a two-phase interleaved boost converter and a three-phase three-level NPC inverter.

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.

Are multi-function energy storage a good idea?

Theoretically, multi-function forms of energy storage are also proposed in and BESS have also been explored significantly on their real power benefits such as peak shaving, load leveling, Vehicle-2-Grid (V2G) smart charger integration, and renewable energy integration [24, 25].

How to choose a multifunctional inverter?

The rated power of the multifunctional inverter must be considerably higher than the peak power of the PV array to ensure a significant increase in power quality under all environmental conditions. The trial-and-error approach used to select the type and number of the membership functions is time-consuming and labor-intensive.
