π Microgrids are decentralized power systems that allow for on-site distribution of power generated by smaller systems such as solar PV and wind.
ποΈ Microgrids function like self-sufficient villages, reducing reliance on centralized power systems and providing localized power generation and consumption.
β‘ Microgrids offer advantages such as improved load response, decreased feeder losses, and increased local reliability compared to conventional power systems.
π Microgrids are low voltage networks that provide heat and power to a particular area using generators and loads.
π‘ Microgrids have different structures and architectures, including the use of solar heating systems and storage elements.
π Power electronics interface and converters are required in microgrids to accommodate different loads and voltage/frequency requirements.
π Microgrids can operate as an aggregated system, allowing for control flexibility and the ability to switch between the utility grid and standalone operation.
π Microgrids enhance local reliability and security, enable grid modernization, and integrate renewable energy sources.
π± Microgrids promote energy efficiency, reduce losses, and have the potential to reduce large capital investments.
β‘οΈ Microgrids provide a solution for regions without access to electricity, reduce peak loads, and encourage third-party investments.
π Microgrids meet user needs for critical loads, promote demand-side management, and empower community energy independence.
π Microgrids allow for community development in electricity supply and give local bodies control over the energy distribution.
π‘ Microgrids have a wide range of applications, such as meeting the energy needs of commercial, industrial, institutional, and domestic areas.
π Microgrids are particularly beneficial in off-grid areas where people lack regular access to electricity, and can help reduce energy costs and generate revenue for large entities.
π‘ Microgrids consist of power electronics systems, such as LED lighting and renewable energy interfaces, to improve efficiency and performance.
π Power electronics play a crucial role in modern microgrids by connecting storage, distributed generation systems, and loads through power conversion.
π Microgrids can be classified based on capacity, location, and function demand, and can be AC, DC, or hybrid in nature.
π Microgrid classifications based on capacity: simple microgrid (below 2 MW), corporate microgrid (2-5 MW), feeder area microgrid (5-10 MW), substation area microgrid (above 20 MW), and independent microgrid for remote areas.
π Grid-connected microgrids connect to the common grids, while independent microgrids use diesel generators or small units to meet power demand in off-grid areas.
π Microgrids can be classified as DC microgrid, AC microgrid, or AC-DC hybrid microgrid. DC microgrid involves distributed generation, storage elements, and DC and AC loads connected via converters and inverters.
π Microgrids have both DC and AC components, with bidirectional power flow.
β‘ DC microgrid consists of a three phase bus, DC bus, and bidirectional DC to DC converter.
π AC microgrid includes an AC bus, battery storage element, and bidirectional AC to DC converter.
