Grid Connected Microgrids

Microgrid benefits

Microgrids have historically been popular in remote areas like islands that are without access to a national electricity transmission network. Substantial cost reductions in solar PV and lithium-ion batteries are enabling clean energy microgrids to be built in cities.

Planet Ark Power is able to create a grid-connected microgrid. This enables major benefits including:

  • Economics are much improved through the ability to trade the spot market and engage in Frequency Control Ancillary Services (FCAS).
  • Improves grid security and stability by enabling participation in FCAS. With AEMO and state governments, like SA, encouraging distributed energy sources.
  • Enables the unlocking of other income streams from the connection of onsite diesel or gas generators that would otherwise be idle and only used for backup.
  • Provides the site with cheaper, cleaner power, at zero marginal cost, unlike other energy sources such as gas.
  • Power security through islanding capability as the battery and the solar can come on to power the site almost instantly ensuring no loss of power continuity

Planet Ark Power is expected to install a very large Microgrid in 2018

  • 4.2 MW of rooftop solar +3 MWh of batteries in conjunction with Schneider Microgrid software to linked to network operator systems to provide micro-grid functionality.
  • 100 x dSTATCOM units and Elevare control software provides control voltage on the feeder to allow solar export and battery export.
  • Network Operator, SA Power Networks (SAPN) then wants to replicate to other sites over 5 years.
  • This project will help prove the scalability of the solution.
