the recent publications bridging the power electronics and power system reliability are discussed in detail. Finally, the main findings included in this overview paper can serve as basis for
The impacts of climate change drive the motivation behind establishing a net-zero carbon power microgrid. Stakeholders must develop a microgrid infrastructure where all power sources are derived from renewables,
Grid integration of renewable energy (REN) requires efficient and reliable power conversion stages, particularly with an increasing demand for high controllability and flexibility seen from
Figure 1. Power electronic converters in microgrids. In an AC microgrid, power electronic converters are used to convert DC power (from PV cells, batteries, EVs, etc.) or variable frequency AC power (from wind turbines) into 50/60 Hz AC power so that the power can be fed into the AC bus and supply loads.
Microgrids can provide a localized and community-based approach to energy management that is well-suited to urban environments. For example, microgrids can power individual buildings or neighborhoods, reducing the strain on the main power grid and improving the overall resilience of the energy system.
Microgrids can provide a reliable power source to remote and rural communities not connected to the primary power grid. These communities often suffer from frequent blackouts and brownouts due to the poor condition of the primary power grid. Microgrids can provide a stable source of power that is not dependent on the primary grid [ 66 ].
Microgrids also use power electronic interfaces as inverters, which can also introduce harmonics in the grid. Advanced control strategies, such as direct power control (DPC) and droop control, use the inverters to regulate their active and reactive power based on the grid conditions [ 46 ].
A PFC controls the power flow between different energy sources, energy storage systems, and loads [ 63 ]. Additionally, the microgrid’s inverters may use advanced protection strategies. These devices control the power flow between the microgrid and the primary grid.
