Comparison between household photovoltaic and microgrid

A performance comparison between a single household and a microgrid PV system is conducted by developing efficient and low-cost off-grid PV systems. The battery model for these two systems is 1.6 kWh daily load with 0.30 kW peak load for a single household and 193.05 kWh/day with 20.64 kW peak load for an off-grid PV microgrid.

Two ways to ensure continuous electricity regardless of the weather or an unforeseen event are by using distributed energy resources (DER) and microgrids. DER produce and supply electricity on a small scale and are spread out over a wide area. Rooftop solar panels, backup batteries, and emergency diesel generators are examples of DER.

A comparison of the proposed DC microgrid (PDC) with the new DC operation in the literature (NDC) for the household appliances individually. It is found that the total daily energy saving for AC is 2696.7Wh, while it is 531.6Wh for NDC.

The large-scale development of household photovoltaic in rural areas increases grid operation challenges and leads to higher costs for its access to the grid. To promote self-generation and self-consumption of photovoltaic, this paper investigates methods to enhance the photovoltaic consumption potential in village microgrid.

The results show that the proposed DC microgrid system can accurately provide the voltage required for small household DC appliances, such as 24 V, 12 V, 5 V, 3.3 V, etc., and the direct supply of DC appliances using solar photovoltaics can currently reduce about 20% of power consumption.

6 FAQs about [Comparison between household photovoltaic and microgrid]

What are the benefits of a solar microgrid?

Cost-Efficient Operations: Solar microgrids empower businesses to reduce energy costs significantly. By harnessing solar energy, companies can offset reliance on traditional grid electricity, thus cutting down operational expenses. Reliable Power Supply: Ensuring uninterrupted power is crucial for businesses.

How efficient is a PV home microgrid system?

For the traditional ON-grid PV home microgrid system, Figure 1(a) shows about 81% cumulative efficiency, which is due to the existence of four main energy converters in the system.

Are solar microgrids a viable alternative to traditional grid infrastructure?

Cost-Effective Infrastructure: Building traditional grid infrastructure in remote areas can be prohibitively expensive. Solar microgrids offer a more cost-effective alternative, requiring less upfront investment and shorter implementation times.

What is a standalone photovoltaic microgrid?

The design of a standalone photovoltaic microgrid is aimed to find the cheapest way to go for either a single rural house or a group of 200 rural houses with similar load demand as a long-term solution to their local energy challenges.

What is an off-grid PV microgrid?

Therefore, an off-grid PV microgrid was proposed to meet the basic energy demand in rural areas. Energy can be produced from direct sunlight either by using the photovoltaic effect or by using energy from the sun to heat a working fluid to get steam energy that can be used to power up generators.
