6 FAQs about [The relationship between photovoltaic power generation and microgrid]

How can a microgrid improve the reliability of solar PV?

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].

Do PV based microgrids have a negative environmental impact?

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.

What is a technical assessment for a solar PV-based microgrid?

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.

Are microgrids a viable alternative to the power grid?

Apart from the grid connected ones, microgrids are becoming an alternative means for electrifying rural communities where the extension of the power grid are not possible and the transport of the fuels is costly and difficult [6, 7].

What is a PV-based microgrid?

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.

Do microgrids generate more power during the summer?

Fig. 9 illustrates the power generation and consumption distribution among three types of microgrids during typical days. The trend indicates higher load demand and PV power generation during summer, while wind power generation exhibits greater volatility, particularly in the mid-season.
