The role of power converters in interfacing the input with the required output is highlighted. The advantages of solar PV fed DC microgrid are demonstrated by designing and testing a non-isolated high gain high power (HGHP) DC-DC converter to meet the DC distribution voltage level.
The name implies the principle component in a PV-based microgrid is the solar PV system. However, the generated output power of a PV system is dependent on the weather condition, that is, solar irradiance and temperature; and the intermittency in the solar irradiance causes fluctuations in the generated output power of the solar PV system.
In order to overcome the problems associated with the intermittency of solar PV and enhance the reliability, energy storage systems like batteries and/or backup systems like diesel generators are commonly included in the microgrids [11, 12].
Technical assessment is based on the nature of the energy sources and the load of the microgrid. For a solar PV-based microgrid, the main technical aspects that are necessary to be considered include rating of PV modules, tilt angle, fill factor, MPPT, PV efficiency, and efficiencies of the power electronic converters.
Solar PV generation required a high voltage gain for the required amount of power generation. High gain DC-DC converter is the suitable solution for the PV application. Mathematical modelling and full analysis of the proposed topology is done. Brief comparison with all other recently published topologies is incorporated with the work.
Moreover, battery energy systems are also reported to have negative environmental impacts, which is also required to be taken into consideration while sizing/designing a PV-based microgrid [48 - 50]. In Figure 3, the common design considerations for PV based microgrids have been summarised.
