Furthermore, the progress and development of power electronics science have increased the utilization of renewable energy, leading to the formation of “microgrids” . A microgrid is a controllable local network, comprising distributed generation sources, loads, and energy storage systems. A microgrid can be DC, AC, or hybrid (AC/DC) .
The discussed DC microgrid includes a solar array as a distributed generation source, resistance load, and constant power, and a combined battery and supercapacitor storage system, and it can also connect to the AC network. In this microgrid, the combined storage stabilizes the DC bus voltage by balancing production and consumption.
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.
In the proposed system as shown in Figure 2, a 15 MW photovoltaic (PV) generation unit (PVG), 200 mega volt amp (MVA) rated diesel generator unit (DG), wind power plant of 25 MW and battery/ultra-capacitor have been considered in the form of microgrid. Battery and ultracapacitor-based HESS has been considered to emulate the characteristics of VSG.
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.
Also, a combined supercapacitor and battery energy storage system are considered to control the DC bus voltage, which is connected through a two-way DC-DC converter. In this paper, to increase the controllability, the active structure is used for hybrid storage.

This study found that microgrid systems built for the commercial/industrial sector have the highest average cost, at $4 million per megawatt, followed by campus/institutional systems at $3.3 million, utility at $2.5 million, and community at $2.1 million. These differences may be due to economies of scale, with projects that have between 2-10
