4. Smart Grid
• Smart Grid facilitates efficient and reliable end-to-end intelligent two-way delivery
system from source to sink as well as integration of renewable energy sources
• Smart grid will be able to coordinate the needs and capabilities of distribution
utilities, end users and electricity market stakeholders in such a way
 It can optimise asset utilization, resource optimization, control and operation
 Reduction in losses, performance improvement
• It encompasses Integration of Power, Communication, intelligent devices , intelligent
computing system for improved electrical infrastructure that serves consumers with
reliability, quality & affordable price
• Helps both Utility and consumers to participate in the management of electricity
sector inclding efficient utilization of assets – bringing efficiency and sustainability

18. Smart Grid at Dehradun Campus
• First phase of Smart Grid has been implemented at our Dehradun Campus in
collaboration with BSES Yamuna Power Limited
• The Phase - I of the project involves incorporation of Modular Integrated Distribution
Automation System (MIDAS) which is automation of 11KV/415V distribution substation so
as to remotely monitor health of the equipment and also locate the fault in 11 KV
network
• It acquires various DT parameters, such as, oil level, oil & terminal temperature, fire
alarm etc. concerned with monitoring of both the transformers and projects it in the form
of graphs
• It is web based and can be monitored anytime anywhere in the world
• It is just to showcase and knowledge our faculty and students on how a smart grid works
as the current system would be beneficial only in predicting the faults and Condition
Monitoring of the substation, but, in the real world it predicts a fault prior to its
occurrence and automatically informs the concerned person via sms

22. Green Energy Corridor Report
• Large Capacity addition though renewable generation is envisaged in 12th Plan
period
• Studies has been carried out by POWERGRID with demand projection in 12th Plan
for Identification of transmission infrastructure for Renewable Capacity addition in
8 states: Tamil Nadu, Karnataka, A.P, Maharashtra, Gujarat, Himachal Pradesh ,
Rajasthan and J&K
• Evolved Transmission system strengthening has been categorized into two parts
– Intra State Transmission strengthening in STU network
– Inter State Transmission strengthening in ISTS network
• Provision of Dynamic Reactive Compensation for dynamic voltage support

23. Issues in Large Scale Renewable Integration
• Intermittency
• Variability / Uncertainty
• Plants connected at remote/concentrated locations with weak
transmission network
• Renewable plants providing lesser grid support during system
disturbances/exigencies

24. Mitigating Measures for Large Scale Renewable Integration
•
Flexible generation, Ancillary Services for supply-balancing
•
Technical Standard Requirements (Grid code, Connectivity standards, Real time
monitoring etc.)
•
Demand Side management, Demand Response and Storage for load balancing
•
Forecasting of Renewable generation & Forecasting of Demand
•
PMUs/WAMS on pooling stations and interconnection with centralized control
centre for real time information, monitoring and control
•
Policy and Regulatory advocacy for power-balance market and pricing
