Electrical Energy Management
Electrical Energy Management is a system of electronic devices and software used by power grid operators to monitor, control and optimize the performance of the generation or transmission system. Also, it can be used in small scale systems like local grid.
It is difficult to store electrical energy, for this reason the generation and consumption of electricity must always be in balance in order to always maintain a high-quality electricity distribution.
Monitoring and control of electricity consumption is an important part of electricity production and distribution management.
The energy management system can be used to create operational programs and remote control with the following capabilities:
- Appropriate voltage and current control
- Planned shutdown of power system equipment (such as power transmission lines, transformers, etc.) for inspection or repair
- Decision making in emergency situations
It was common to find Electrical Energy Management systems based on proprietary hardware and operating systems until the early 1990s. At the time, suppliers produced their own hardware, and suppliers that did not produce their own hardware often relied on products developed by companies such as Digital Equipment. Currently, Electrical Energy Management systems rely on a model-based approach. Using Electrical Energy Management software allows planners and operators to share a common model, reducing inconsistencies between the two groups and cutting model maintenance in half. Having a common user interface also allows for easier transfer of information from planning to operations.
Proprietary systems became uneconomical, for this reason suppliers began to offer solutions based on industry standard hardware platforms. The popular operating system at that time was Unix. By 2004, various suppliers began offering Windows-based solutions. In 2006, customers could choose Unix, Linux, or Windows-based systems. Newer electrical management systems based on blade servers require much less space. For example, a blade rack with 20 servers takes up about the same space as a MicroVAX server.
1. Energy Efficiency
Electrical Energy Management can be used to achieve energy efficiency through process optimization using energy consumption reports by installed measuring equipment. Newer cloud-based energy management systems provide the ability to remotely control cooling equipment and other electrical energy consuming equipment. by collecting accurate and real-time information for each equipment; We will have a smart, specific and fast function to find and obtain the best way of optimal consumption and thus reduce electricity consumption.
2. Automatic Control in Buildings
Electrical Energy Management can refer to a computer system specifically designed to automatically control and monitor electromechanical installations in a building that consume significant energy, such as cooling, ventilation and lighting installations. The network may range from a single building to a group of buildings such as office buildings, chain stores, university campuses or factories. Most of these energy management systems provide facilities for reading electricity meters. The data obtained from them can be used to perform automatic detection and optimization routines based on repetition and to analyze and forecast annual consumption. Electrical Energy Management systems are also used in commercial units for monitoring, measuring and controlling electrical loads.
Electrical Energy Management System Structure
The management system has two levels. The first level is called field control, which includes controllers and all measuring devices. Measuring devices provide information on the quantity and quality of electrical power. Controllers play roles of concentrators. The concentrator collects data from the measuring devices and sends the data to the operating station, which is part of the second level of the control system. The industrial modem realizes the data transfer between the controller and the devices. In the case of a network error, information is saved whenever the connection fails. After the network communication is restored, the concentrator must capture the lost information and send it to the second layer.
Electrical Energy Management Software Structure
The software environment consists of two parts. The first part of the system displays data with a convenient user interface. This part realizes the connection between the field control level and the operation station level. The second part includes the following:
- Collect information from the first level
- Primary data processing for prediction algorithm
- Preparation of reports
- Error detection (difference between delivered energy and reported energy consumption)
- Verification and correction of data
Energy management software (EMS) is one of the tools that helps a lot in the issue of Electrical Energy Management, and without it, it would not be possible to manage energy in the way it is done today. With the help of this software, everything can be monitored and controlled instantly. One of the facilities that the Electrical Energy Management software provides to us is the calculations related to electricity consumption by subscribers, which by controlling electricity consumption and issuing bills for them, it is possible to categorize subscribers according to their consumption, such as Subscribers with low consumption, high consumption, etc.
Electric energy management software allows monitoring consumption, preparing reports and making automatic decisions in certain situations. Monitoring includes trend analysis and energy consumption tracking to identify optimization opportunities. The report includes validation of energy data, benchmarking, and determination of energy consumption reduction goals at the macro level. Decision-making is also control and automatic momentary responses to improve and maintain the quality of power energy distribution.
