Traditional SGS is building energy management system with distributed energy resources includes heat and cooling system control, lightening control and electric power monitoring, but Dubai SGS is combination of several sub SGS and realization of total control center.
For Dubai, the water is one of essential energy usage part, so this project includes water meter and it makes more energy efficient building.

Above images shows network configuration.
Interfacing with several SGS networks and TOC, it gathers huge kinds of data by real time.
This project was deployed with Power Scene Network version and database, and for high response, individual Database and FEP server was also introduced.

Above images shows DEWA SGS system configuration.
For monitoring electric energy usages, AMI, Smart meter, etc. was installed.
For energy savings, distributed energy resources like PV, battery storage, wind turbine, occupancy sensor, chiller control system and thermal energy storage system.
Power Scene can communicate these devices using IEC 68150, DNP 3.0, Modbus.
Major screen is as follows
- Total operation screen
- Electric grid screen
- Water supply, usage and recycling
- PCS control
- Chiller facilities monitoring and control
- Air handling unit control
- Lightening control
- Statistic reports

Above picture shows water usage, supply and recycle.
.png "PCS%20Monitoring(0).png")
Above picture shows PCS control. PCS is important component to control battery and PV.
In this project, hybrid type PCS was deployed. And using scheduler and automation function, the charging and discharging function is operated automatically and safe.

Dubui is very hot area, so cooling system energy consumption is key point to reduce energy saving.
All cooling energy consumption is monitoring for each parts to reduce consumption.

Above picture shows air handling unit status with environmental information such as temperature and air quality.
.png "Light(0).png")
Using occupancy sensor, the light is controlling automatically.

Above picture show power demand, if operator set load control lists, Power Scene system control each devices to meet target energy usages limit.
.png "Statistics(0).png")
Above picture shows statistical report for distribution and water data by daily, monthly and yearly. Also the user can identify energy consumption for each building easily.
