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-led constraints, and as such will respond appropriately to all types of DERs, including energy storage.

Energy Market Facilitation
 

Main Functionality :

Integration of all types of controllable demand and generation of all sizes is a central feature of Constellation. Real time control of smaller wind, solar, synchronous, demand and storage systems etc is possible both directly and indirectly via aggregators. This module provides a rich interface to allow virtualisation of aggregated assets for operation by the standard Constellation applications thereby facilitating the implementation of Energy Markets.
