Microgrids : an indian perspective.

  1. 1. Microgrids: the panacea for country’s power crises. sumit raturi. Dept. of electrical engg. Thdc institute of hydropower engg & tech.
  2. 2.  Microgrid : an introduction. • A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. If desired a microgrid can connect and disconnect from the grid to enable it to operate in both grid- connected or island-mode.
  3. 3.  Classification of microgrids. i) Large grid connected microgrids. ii) Small grid connected microgrids. iii) Large remote microgrids. iv) Small remote microgrids.
  4. 4.  Architecture of microgrids. A microgrid consists of following components. i) main substation. ii) smart meters. iii) storage devices. iv) Distributed resources. v) Cogeneration systems.
  5. 5. Modes of operation . Grid connected mode. in this mode the microgrid works in integration with macro grid. The two grids are connected at the pcc with the help of either a ckt breaker or a static switch or a power electronic interface.
  6. 6. Island mode . In this the microgrid works alone on its own resources either intentionally or due to failure of main grid. however special attention is required when transition takes place from one to other mode due to transients.
  7. 7.  importance & benefits . • It enables modernization of the grids. • It enhances the integration and the usage of distributed and renewable energy resources. • It meets up with the end user needs. • It provides support and backup for main grid.
  8. 8.  Economic issues & constraints. • Installation requires huge investment and research. • Transition from grid connected to isolated mode is a tricky job. • Co-ordination of distributed energy resources is difficult. • Requirement of public private partnership.
  9. 9. Deployment in India. • With a installed capacity of 253.4 GW India is the fourth largest producer of electricity. • The high availability of DERs and renewable energy resources makes microgrid a good choice. • It can prove to be the panacea for rural electrification problems.
  10. 10. existing microgrid ventures. • Sagar island microgrid project of( 200+450)Kw, in Sunderban, West Bengal. • Husk power systems plant powered by rice husk in Champaran Bihar. • Other firms such as naturetech infra, minda nextgen tech, gram oorga etc have installed projects in UP & Bihar. • SunEdision has also installed a miniproject but plans to install much bigger units.
  11. 11. Case study : husk power systems. • In 2007 Husk power system led by Gyanesh Pandey(CEO) started a rice husk powered microgrid in tamkuha Bihar with help of MNRE. • Provides electricity for 2 lights & a mobile charger at 100 rs pm to a family. • The biomass gasification system that Husk uses is a 32 kW system that can electrify larger villages (about 500-700 households).
  12. 12.  Future aspects : the road ahead. • once the technological and financial probs. are addressed they will solve most of the grotesque crises. • Latest technologies such as smart grids, nano batteries, fuel cells etc will help in advent of microgrids. • Its just not a glimmer of hope but has an immense potential to provide continuous electricity to over 300 mn unprivileged Indians.
