Photovoltaic microgrid system design specifications

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.

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].

Does solar PV affect power factor in microgrids?

PV systems can affect the power factor (PF) in an electrical system and microgrids can have unique power factor needs. The solar PV project should be analyzed for PF impact and benefit from a technical and economic perspective in grid-connected and islanded modes.

How much power does a microgrid have?

Table 2. Optimization results of the investigated microgrid configurations. According to the design specification of the real field system, the PV and converter capacities are recorded at 32 kW and 30 kW, respectively.

What is a PV inverter & a microgrid?

The inverter shall be capable of real-time data logging, alarm reporting, and communication with a remote power system controller. PV systems can affect the power factor (PF) in an electrical system and microgrids can have unique power factor needs.

What is a microgrid system?

A microgrid system is a low/medium voltage power network that hosts distributed and renewable energy sources, storage devices, and loads, with a view to best utilise renewable energy resources and reduce dependency on fossil fuel-based energy sources to ensure reduction in greenhouse gas (GHG) emission.
