Microgrid control is a complex and many-layered topic. The first decisions a researcher or microgrid implementer must make are related to the structure of the control architecture – whether it will be centralized, distributed, or somewhere in between; how the control hierarchy will be arranged (if any exists); and whether the controller will perform supply side management (such

•Opportunities are through microgrids, electric vehicles, and wastewater treatment. •High capital cost and lack of policy restraint in smart grid implementation. Bhattarai, T.N., Ghimire, S., Mainali, B. et al. Applications of smart grid technology in Nepal: status, challenges, and opportunities.
To meet such high demand, the existing power grid of Nepal needs sheer modernization to ensure better management of produced energy, reducing losses to acceptable limits, utilization of domestic resources curtailing import, and a flexible distribution system. Electricity demand at different scenarios with predicted ones (Data Source: (WECS 2017 ))
Consequently, these smart microgrids can be integrated with the national grid to form a large-scale smart grid, thus making it flexible, resilient, reliable, and energy-efficient. Nepal has experience of running EV technology like trolleybuses and electric three-wheelers named “Safa Tempos” inside the KaV since the 1970s and 1990s, respectively.
In addition, there are no well-defined rules or guidelines in Nepal to govern smart grid efforts. The majority of present legal and regulatory frameworks were created to address existing networks and utilities. As a result, current legislative and regulatory frameworks will need to be amended to facilitate the deployment of smart grids.
With the advent of smart features mentioned above, active demand response management can be achieved in the smart microgrids, thereby shifting peak load to an off-peak hour, reducing the undesired power outages, lowering the energy production cost, and bettering the power quality.
