energy management system (smart grid) (EMS)

An energy management system, orEMS, is a computer system for sensing energy flows in a utility network. EMS systems are used by utilities and dispatchers for real-time monitoringand control of smart grids and other power systems.

EMS systems control complete power grids from power generation through transmission and energy storage to the end user and improve energy efficiency. They provide grid stability and compensate for temporary overloads.

In power distribution networks, there are countless components that transmit data to energy management systems. This data is converted into control algorithms, optimizing and controlling power distribution. On the consumer side, components include smart meters( SM) with automated meter management( AMM), DMS systems, and load management. Further data comes from the energy storage systems and the various energy-generating systems and plants. Corresponding monitoring, control and optimization functions are known as Supervisory Control and Data Acquisition( SCADA) and are therefore also referred to as SCADA/EMS.

To ensure interoperability, energy management systems have been defined in DINENISO 50001. In addition, some EMS manufacturers have opted for the OpenVMS or Unixoperating system. There are also some Windows-based solutions.
