JNTU B.Tech IV Year SMART ELECTRIC GRID Previous Question Paper (September - 2022 - R16)

Yes, the smart grid is fundamentally a Green Grid because it integrates renewable energy sources and optimizes energy efficiency, significantly reducing the carbon footprint of the power sector. The justification lies in its ability to manage the intermittent nature of renewable energy, such as solar and wind, through advanced Demand Side Management (DSM) and energy storage systems. By employing real-time monitoring and automated control, the smart grid minimizes transmission and distribution losses, reduces the reliance on fossil-fuel-based peaking plants, and facilitates the integration of electric vehicles as mobile storage units. Consequently, it promotes a sustainable, low-carbon energy ecosystem that aligns with global environmental goals.

A Building Integrated Power System (BIPS) transforms buildings from passive energy consumers into active prosumers. Its primary advantages include increased energy self-sufficiency, reduced grid dependency, lower operational costs through peak shaving, and improved power quality. By utilizing on-site generation, buildings can mitigate the impact of grid outages and contribute to overall grid stability.

The relevant nodes of innovation include:

• Distributed Energy Resources (DERs): Integration of rooftop solar photovoltaics, micro-wind turbines, and fuel cells directly into the building envelope.
• Advanced Energy Storage Systems (ESS): Utilization of lithium-ion batteries or thermal storage to manage energy supply-demand mismatches.
• Smart Energy Management Systems (SEMS): AI-driven controllers that optimize load scheduling, HVAC efficiency, and lighting based on real-time pricing and occupancy.
• Vehicle-to-Building (V2B) Technology: Enabling electric vehicles parked at the facility to act as temporary energy buffers, discharging power during peak demand periods.
• Smart Metering and IoT Infrastructure: Providing high-resolution data for granular control and automated feedback loops between the building and the utility grid.
