Low voltage micro-grid in particular has attracted increasing attentions from researchers. Micro-grid is a small-scaled autonomous power grid system that consists of multiple energy generations from renewable and non-renewables resources, energy storage systems (ESS) and power electronic converters.
A microgrid is a compact, low-voltage power system that combines load, distributed generation, and energy storage. Figure 2 shows a block diagram of an overview of a microgrid. A microgrid can function in either an on- or off-grid mode and achieve a seamless transition between the two modes.
Besides the topology, the energy management and control strategies used in HESS are crucial in maximising efficiency, energy throughput and lifespan of the energy storage elements [33 - 37]. This paper reviews the current trends of battery-supercapacitor HESS used in standalone micro-grid.
microgrid typically uses one or more kinds of distributed energy that produce power. In addition, many newer microgrids contain battery energy storage systems (BESSs), which, when paired with advanced power electronics, can mimic the output of a generator without its long startup time.
