ENERGY MANAGEMENT SYSTEM (EMS)

Energy management system (EMS) is the process of monitoring, coordinating and controlling the generation of the system, transmission and distribution of electrical energy. It is performed at the centres called 'system control centres, by a computer system is known as Energy Management System (EMS). Data acquisition and remote control are performed by the computer system called SCADA, which forms the front end of EMS. The EMS communicates with the part of generating, transmission and distribution systems through SCADA systems.

Energy Management:

The Energy Management system consists of Automatic Generation Control, energy management, security control, load management and SCADA. The various functions that involved in energy management systems are:

 

• Productions cost of calculation.
• Maintenance scheduling system.
• Security constrained dispatch.
• Transmission loss minimization.
• MW interchange evaluation.
• Hydrothermal scheduling system.
• Fuel scheduling to plants.
• Unit commitment system.
• System load forecasting - from 1 to 7 days.

Load Management:

Remote Terminal Unit is a system that installed at various substations. It will give information about status and measurement for different substation.  Remote Terminal Unit can also monitor different process. The function of load management are

• To control the customer load through appliance switching and through voltage control by background.
• Circuit continuity analysis.
• Implementation time dependent pricing.
• Power factor and voltage control.
• Service restoration control.
• Fault location and circuit topology configurations.
• Load management - control customer load.
• Customer meter reading.
• Data acquisition.
• Feeder switch control.
• Preparing distribution map.
