Abstract

Renewable and sustainable energy and power electronic applications emerge in green energy utilization in the wind photovoltaic (PV) microgrids, energy storage, and battery charging systems. The power electronic DC-to-DC and back-to-back converters serve the efficient energy transfer from wind/fuel cell/solar PV sources to load canters using a green plug, switched filters, static synchronous compensator (STATCOM), and other flexible alternating current transmission system (FACTS) devices using fast-acting decoupled optimal control strategies. The advanced control techniques optimally change and modulate PWM (pulse width modulation) switching control of the converter and green plug system.
A novel PV-powered boost converter device is proposed to store the battery with a DC green plug scheme in this chapter. The proposed green plug and boost converter is switched with a pulse width modulation (PWM) signals. These signals are generated by (proportional integral derivative) PID (proportional integral derivative) control and driven by an error signal operated by dual-loop controllers. These double loops use the current and voltage error signals to obtain the total error signals. The error amplifier controllers were decoupled to increase efficiency and stability. The control theory of this system is investigated in more detail in this chapter.
This chapter also gives more detailed information about the PV model design and controller design and theory. Various controllers are investigated and compared in this chapter. The converter topology is analyzed in more detail. Different loads and their impact on the general system are topics that are investigated. Different green plug topologies and how do they affect the system are research topics in this chapter.
The simulation models are designed and tried in MATLAB/Simulink software, and obtained results were tested and compared for different climate conditions. The proposed system with a green plug filter increases the total system efficiency as seen in simulation results. The proposed scheme provides better energy-efficient utilization and battery fast charging with reduced inrush current conditions and modified hybrid charging modes. This chapter supplies basic information about PV-powered converter control systems and how they are designed for DC green plug topologies and how they affect the DC systems. The detailed simulation model investigation supplied readers with more helpful information about this matter and its application practically.
The proposed scheme ensures reduced switching transient inrush current conditions while ensuring efficient energy delivery and utilization. The novel green plug scheme using supercapacitor provides energy storage and minimum excursions under load excursions and changes in PV and solar insulation (SX) and junction temperature (TX) variations. The decoupled multi-loop controller is effective as it ensures time scale decoupled action with dominant and supplementary loops. The modified PWM/switched DC-DC converter is a fast action with reduced switching losses.
