Multi-Vector energy integration for Rural Microgrid

Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)

The multi-energy system caters the electrical and thermal load of remotely located village Bilaput (Dist-Koraput) and Khajuripadar (Dist-Ramgiri) in Odisha. This performed by the integration of Solar PV, Battery, 2-stage Biomass Gasifier and Green Chill as generation unit in microgrid. Whereas, the load side contains, a Cold room to store perishable items, Flour Mill, Millet processing unit, Leaf plate making machine and other domestic loads in the premises. The cold room is associated with adsorption based thermal chiller and vapor compression system (VCS) based electric chiller which run from exhaust heat of Biomass Gasifier, Green Chill unit and Electricity produced from Solar PV system or Gasifier unit. This multi-energy microgrid is developed after determining the village load demand by surveying and then optimally sizing and scheduling of the sources for optimal dispatch of energy.

Salient Features/Advantages

  • Coordinated approach for multi-energy system providing electricity and cooling solutions for remote locations
  • The integrated system has autonomy of 3-days to run cold storage*.
  • In the unavailability of solar energy 2-stage biomass gasifier can simultaneously maintain temperature of cold room using thermal system absorption system and produce electricity from alternator unit that can be feed in battery storage and other electrical loads
  • The VFD based control panel for operation of VCS based chiller unit minimizes the initial inrush current of compressor unit, which in turn helps to appropriately select the sizing of solar PV inverter

Key Outcomes

  • The socio-economic standard of the village has improved by the installation of microgrid, as it has helped the village residents to be self-reliant by generating revenue from using cold room to store perishable items and running Raggi mill, and Millet processing unit
  • Various entrepreneur opportunities are rising from the natural dye-making, textile colouring machine, and leaf plate (patta) making machine installed in the premises
