What is DERMS
A distributed energy resources management system (DERMS) is a platform which helps mostly distribution system operators (DSO) manage their grids that are mainly based on distributed energy resources (DER). By lack of a common definition, a DERMS thus – depending on your point of view – is something similar or even identical with a Virtual Power Plant (VPP).
On some key aspects, people seem to agree: DERMS is a software platform that is used to organize the operation of the aggregated DER within a power grid. The usual DERMS application is found at the distribution grid level. DERMS typically require a more full-fledged integration of various other systems such as a distribution management system (DSM) for integrating it with a utility. Furthermore, an outage management system (OMS) or a supervisory control and data acquisition (SCADA) system is usually needed to provide all DERMS functionality.
