Rural Microgrid
​
The Rural Grid consists of a distribution network with a high level of wind DER penetration. The topology follows a rural pattern. The grid also includes a diesel generator which can be used to anchor the grid if it is run in island mode as a microgrid. When transitioning to a microgrid the VPP Application is used to reduce the active and reactive power flows to an acceptable level before isolating the microgrid, to avoid destabilising the anchor generator. When islanded, the Microgrid Controller maintains grid stability until the microgrid can be re-connected to the wider grid.

Main Functionality :
Microgrid / Islanding
The Microgrid Controller performs constant analysis of the network in real time to determine the power flows and network voltages throughout the network area constantly balancing load and generation in realtime. The controller maintains all voltages and powerflows within the network constraints and constantly maximises the headroom and foot-room available at the grid forming generator to respond to unexpected events network disturbances such as sudden loss of demand or generation capability.
Main Functionality :
Virtual Power Plant
The Virtual Power Plant Module (VPP) can provide ongoing MW and MVAr support services at the point of delivery i.e. the Grid Supply Point. The VPP module determines the amount of MW and MVAr available in realtime from each of the participating DERs , allowing for network constraints and provides an aggregated MW and MVAr
Main Functionality :
Thermal Constraint Manager
This module monitors for thermal and voltage violations in realtime. On detection of one or more network violations, DERs contributing to the violations are curtailed in order to resolve the problem. DERs can be constrained based upon user-defined Principles of Access (POAs). The ANM module can respond to both demand-led and generation-lead constraints, and as such will respond appropriately to all types of DERs, including energy storage.
