- 3. INTRODUCTION TO POWER GRID Early 60’s •Grid management on regional basic started •State grids were inter-connected to form regional grid •India was demarcated into 5 regions namely Northern , Eastern , Western, North Eastern and Southern region. Oct’ 1991 •North Eastern and eastern grids were connected. March 2003 •WR and ER-NER were connected Aug’2006 • Northern and East grids were interconnected thereby 4 regional gridds Northern , Eastern, Western and North Eastern grids are synchronously connected forming central grid operating at one frequency. Dec’ 2013 • Southern Region was connected to Central Grid in synchronous mode with the commissioning of 765kV Raichur- Sholapur Transmission line thereby achieving “ ONE NATION ONE GRID ONE FREQUENCY”.

- 9. OBJECTIVE OF POWER GRID:- Principle concerning national grid is total import equals to total export. import=export Power grid is responsible for the transmission of more than 50% of the total power generated in India through its network. Its businesses include power transmission and distribution and energy trading. To facilitate private sector participation in transmission system through Independent Private Transmission Company/ Joint Ventures. Geographically widely spread Indian Grid can facilitate interconnections with neighboring countries like India-Nepal, India-Bhutan, India-Bangladesh. Restoring power in quickest possible time in the event of any natural disasters like super cyclone, flood etc. through deployment of Emergency Restoration Systems.

Factor affecting the performance of existing grid • Increasing demand of electricity • Supply shortfalls of electricity • Need of reducing losses • Peak demand management • Integration of renewable energy generation systems • Solution to global warming • Effective use of electrical vehicles • Better consumer satisfaction • Overcoming difficulties in metre reading • Poor efficiencies of conventional power generation systems • Potential of technological advancements and new business opportunities
- 11. DISADVANTAGES OF POWER GRID:- Some power is wasted heating the cables. Overhead power cables and their supporting towers are an eyesore in some places. If underground cables have to be used they are much more expensive. Smaller local electricity generating projects, such as wind turbines and/or panels of solar cells, are unreliable compared to a national grid fed by major fixed power generating stations. Remote village links will drag down the steady-state stability of the entire grid because of poor voltage profile(may cause frequent outrage disturbance).

- 14. WHAT MAKES A GRID SMART? The digital technology that allows for two-way communication between the utility and its customers, and the sensing along the transmission lines is what makes the grid smart. STANDARD DEFINITION BY EUROPEAN TECHNOLOGY PLATFORM FOR SMART GRIDS(2006): A Smart Grid is an electricity network that can intelligently Integrates the action of all users connected to it-generators customers and those that do both in order to efficiently deliver sustainable economic and secure electricity supplies. A smart grid employee’s innovative products and services together with intelligent monitoring, control communication and self healing technologies.
