This document discusses the integration of smart grid technology with renewable energy sources for energy demand management. It provides motivation for this integration by highlighting issues with India's traditional electric grid like pollution from non-renewable plants that causes health hazards. The solution proposed is a smart grid that reduces pollution and enables demand management through technologies like microgrids. It then summarizes a case study in Puducherry, India where a smart grid pilot project was implemented combining distributed renewable generation, smart homes, and smart meters to automatically manage energy demand during peak hours.
Integration of smart grid with renewable energy
- 1. Integration of Smart Grid with Renewable Energy for Energy Demand Management Presentation by Sagar D durgada.sagar.1@gmail.com
- 2. Why do we require this integration? • Traditional electric grid – unable - reliable, efficient & clean energy • Rapid industrialization • Non-Renewable energy resources – major health hazards • The solution - FutureVision – Smart Grid - efficient, reliable & clean future • Two major advantages in smart grid: 1. Reduces Pollution 2. Demand electricity • Microgrid - advanced, intellectual, localized, small scale grid
- 3. Motivation for Smart Grid technology • According to Puducherry case study • A. Environmental Ramifications in India due to Non-renewable Power Plants • B. Unplanned Black-Outs, Power Shortage & Power theft
- 4. Environmental Ramifications in India due to Nonrenewable Power Plants • 28% - Renewable energy power plant | 72% - Non Renewable … • Thermal coal power plants - major deaths and health hazards of millions people every year • Greenpeace environmental organization - greenhouse effect by 60% - neither any regulation nor any preventive measures on pollution control • Approx. 120,000 people kill due to coal electricity generation • booming industrialization - public health crisis with 80- 120,000 premature deaths and 20 million new asthma New Delhi Locals take anti-smog precautions
- 5. Vinuta Gopal of Greenpeace said: “The ongoing coal expansion create major bad impacts on the environment and stress out ecosystem which is irrational & dangerous. Large coal mining has assessed impacts of destroying India’s forests, tribal communities & endangered species. Low carbon contain coal has unable to full-fill the energy security. India has to take some efficiency measures, wind, biomass and solar”
- 6. World Nuclear Association review for Greenhouse Gas emission
- 7. Unplanned Black-Outs, Power Shortage & Power theft • Two severe power blackouts affected most of northern and eastern India on 30 and 31 July 2012. • The 30 July 2012 blackout affected over 400 million people - largest power outage in history • Estimated 32 gigawatts of generating capacity was taken offline.
- 8. RENEWABLE INTEGRATION WITH SMART GRID :MICROGRID • Macro grid has drawbacks - power loss, energy demand management and global greenhouse gases emission • Microgrid - advanced, intellectual, localized, small scale grid – Autonomously • MicrogridConcept
- 9. Power Grid Corporation of India limited undertaking Puducherry Smart Grid Pilot project • five residential smart home consumers • consist of distributed generation (DG) plants, power converters, InformationTechnology network, and Smart electrical network with intelligent Home equipment • renewable energy resources :- Solar-photovoltaic system, micro wind, mini combined heat and power biomass - distributed generation (DG) of electrical power. • 20kilowattsTri-hybrid | solar power – 10kw, wind turbine – 5kw, biomass gasifier – 5kw • Variable speed turbines – uncertain and intermittent by nature
- 10. ENERGY DEMAND MANAGEMENT BY SMART HOMETECHNOLOGY • Smart Home - energy demand management by using smart meters & smart appliances. • Home area network makes the intelligent combination & control between smart appliances with smart metering system. • In the home area network (HAN) smart home appliances & smart meters communicate intelligently to manage Peak electric demand.
- 11. A. Smart Home • 2BHK smart home developed as pilot project – energy demand management study • Communicating, decision making according to peak load • automatic communication with electricity utility to manage peak load demand of electricity • At Puducherry pilot project, many electric loads likeTV, refrigerator, two CFL, washing machine, dish washer, fans & thermal loads are used in study of efficient electricity management during peak hours • auto-scheduling & time priority based use of home appliances • Smart sensor data analysis
- 12. B. Smart Meters • Smart meter - digital meter - record consumption of electrical power - advanced intelligent and communication system. • It measures : 1. instantaneous power 2. amount of energy consumed 3. Power factor 4. reactive power 5. system voltage 6. frequency with high accuracy. • Communication with smart home appliances and utility. • Enables two way communication between smart home appliances, smart meter and utility - advanced metering infrastructure (AMI). • AMI – supports demand side management • DLMS/COSEM data transfer protocol • User friendly - key pad or touch screen interface
- 13. C. Energy Demand Management of Smart Home • Stores data at specific interval and transmit it to utility control center for demand side management • Components ofAMI - electronic meter module, network system and software • Two type of information flow: 1. First from sensors and electrical appliance to smart meters called home area network (HAN) 2. between smart meters to utility data center
- 15. CONCLUSION • Smart grid power system enables consumers to adjust their power consumption according to peak load condition. • Saving energy bill for household • Consumers play greater role for shifting their peak hour load to non peak hours. • integration of smart grid with renewable energy resources contributes clean-green energy to reduce hazardous impact on environment
- 16. Thus, Smart Grid • integrate a variety of renewable resources for power generation • with distributed generation, power transmission will be in both directions • network-wide distributed energy generation • Integrate demand response and demand side resources • Increase overall generation by the connection of generators of all sizes and technologies • Reduce the environmental impact • high levels of system reliability, quality and security of supply
