“…A buck-boost converter design reduces the output voltage while amplifying the output current [29], proving indispensable in the quest to optimize power transfer through impedance matching. As observed in the works of [2], the functionality of the buck-boost converter design hinges on the principles of energy transfer in inductors and capacitors, switch-duty cycles, ripple characteristics, and efficiency optimizations. The hybrid system's efficiency largely depends on how effectively power is transferred from the solar panels to the energy storage system and then to the load [24].…”

Microgrid stands for the participation of renewable sources such as solar and wind in the existing energy system in order to increase the availability and reliability of energy for consumers and to make the atmosphere carbon-free by reducing dependence on the main grid. However, the non-linearities inherent in the nature of the microgrid and network components make the programming process complex. Therefore, the efficient but linear model for microgrid resource planning algorithms is gaining interest today due to its simplicity and computational speed. On the contrary, for demand-side management, reducing the peak demand price by using different methods such as load trimming and valley filling by varying the use of flexible loads on the consumer side, which is an easier option for microgrid operators, rush hour price for consumer satisfaction. This paper gives an idea of the above purpose by designing an average model of a solar microgrid with the implementation of the maximum power point tracking (MPPT) algorithm method for stability of the system frequency and a battery storage system with a controller. You then plan the microgrid using the demand side management (DSM) method in order to reduce the cause of the price spikes.

“…where V Q and V D are voltage drops across transistors and diodes, R i , R L , R Q , and R D are resistive components of the input filter inductor, energy transfer inductor, and switches, and i d , i L , and I out are the filter inductor, energy transfer inductor, and load currents. With the same duty cycle and parameters for the inductors and capacitors, the modified buck-boost converter has a lower voltage drop compared to the conventional boost DC-DC converter with a difference in the resistive component of the input-filter inductor (R i ) with factor α 2 [43]. As the voltage drop also represents conduction loss, conduction losses in input filters will be lower than the ones in conventional boost DC-DC converters.…”

“…However, a buck-boost converter has fewer components; therefore, the manufacturing cost is lower. By modifying the conventional buck-boost topology as has been described in [43], the converter has a competitive edge against other topologies. A novel multileveling scheme is also proposed in this paper to enable a high voltage ratio without sacrificing modularity by maintaining the same rating for the same components at all levels.…”

Raising the electrification ratio to 100% is still a formidable challenge in Indonesia, especially in the remote areas of the eastern part of the archipelago. A DC microgrid system is one of the most viable solutions to increase the electricity supply in remote areas, taking advantage of various renewable energy sources that are located near the rural load centers. A DC–DC power converter for a rural DC microgrid system needs to have a high voltage gain to facilitate the power conversion from low-voltage PV output to a high-voltage DC microgrid bus, a very low input ripple current to help maintain the PV or battery lifetime, and be highly modular for ease of transport and assembly. Many topologies have been proposed to obtain high voltage gain, very low ripple current, and modularity. However, they usually use either bulky and lossy magnetic components, are sensitive to component parameter variance and need special voltage-balancing techniques, or have different component ratings for their multilevel configuration which weakens the modularity aspect. This paper proposes a new modular multilevel DC–DC converter that is very suitable for rural DC microgrid applications based on a modified buck–boost topology. The proposed converter is easily stackable to achieve high voltage gain and does not require any voltage balancing techniques, thus enhancing the modularity characteristics and simplifying its control method. Moreover, the ripple current can be reduced by employing a multiphase configuration. This converter can also facilitate bidirectional power flow to serve as a battery charger/discharger. A comprehensive analysis of voltage gain and ripple current are presented to explain the inner workings of this converter. Finally, the performance of this converter is verified through simulation and experiment, showing the converter’s modularity, bidirectional power capability, and potential to achieve voltage gain and ripple-current requirements of the DC microgrid system.
