3. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Introduction What is Microgrid? It is a small-scale power supply network that is designed to provide power for a small community. It enables local power generation for local loads. It comprises of various small power generating sources that makes it highly flexible and efficient. It is connected to both the local generating units and the utility grid thus preventing power outages.

4. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Aim :- To design a reliable and cost-effective microgrid using solar, wind, and energy storage systems for an educational institute operating in island mode. Objectives :- Analyze load demand of different sections. Assess solar and wind potential. Optimize size and placement of DERs. Integrate batteries and backup generators. Develop an efficient load management strategy. Conduct cost analysis for feasibility.

7. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Problem Statement Traditional centralized grids face issues such as high transmission losses, dependency on fossil fuels, and unreliable supply in rural/remote areas. With rising demand and environmental concerns, there is a need for decentralized, reliable, and renewable-based energy systems.

10. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Conventional Grid vs Microgrid Parameter Conventional Grid Microgrid Power Source Mostly fossil fuels & centralized plants Mix of renewables (solar, wind, biomass) + storage Reliability Less reliability High reliability Cost High infrastructure & transmission cost Lower local distribution cost, higher initial setup Environmental Impact Higher emissions (thermal, coal, gas) Greener (renewables reduce carbon footprint)

11. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Application :- Educational institutes and campuses Remote and rural electrification Commercial buildings and hospitals Industrial parks and data centers Military bases and islanded communities

12. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Advantages :- Reduces dependency on national grid Utilizes renewable (clean and sustainable) resources Provides uninterrupted power with storage & backup Disadvantages:- Intermittent nature of solar and wind (weather-dependent) Requires advanced control and protection systems High initial installation cost (PV, wind, batteries)

13. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Future Scope Integration of AI and IoT for real-time energy management. Use of advanced battery technologies (solid-state, flow batteries). Expansion to regional smart grids for energy trading. Incorporation of hydrogen fuel cells as clean backup systems. Policy support for renewable-based microgrids in rural electrification.

14. Dr. Vithalrao Vikhe Patil College of Engineering, Ahilyanagar Department of Electrical Engineering Conclusion :- Microgrids provide reliable, clean, and cost-effective power by integrating renewables with storage and backup. They ensure energy security, reduce grid dependency, and support a sustainable future.
