A Smart Grid Station, SGS, has been inaugurated in Al Ruwayyah, Dubai on Sunday, by H.H. Sheikh Ahmed bin Saeed Al Maktoum, Chairman of the Dubai Supreme Council of Energy, The construction of the new station is part of Dubai Electricity and Water Authority’s, DEWA, efforts to implement technologies which link smart buildings for the exchange of information, improve energy and water efficiency, and optimise renewable energy in smart cities.
The SGS was built in partnership with the Korea Electric Power Corporation, KEPCO, as a result of a fruitful exchange of best practices and experiences in the latest international smart city and smart grid standards.
During Sheikh Ahmed's tour around the station, he was briefed by Saeed Mohammed Al Tayer, Managing Director and CEO of DEWA, on the various sections of the SGS, which uses a variety of smart grid technologies to generate power through renewable sources, such as solar and wind power, and maximise energy efficiency through real-time monitoring and control systems.
The station also allows for the reduction of loads, especially at peak times; peak shift, and the reduction of water consumption.
Sheikh Ahmed, who is also the Chairman of Dubai Civil Aviation Authority, Chairman and Chief Executive of Emirates Airline and Group, was also briefed on the components of the station, which highlight the Smart City model through three concepts or systems: the smart office, smart building, and smart factory.
The Smart Grid Station concept is scalable and allows for the development of individual smart buildings, groups of smart buildings and smart areas, which ensures the efficient reduction of electricity and water consumption as well as carbon emissions, thereby becoming a smart city.
The SGS comprises a 200-kilowatt, kW, photovoltaic solar power production system; a 9-kW wind turbine; and a 500-kilowatt hour lithium-ion battery energy storage system, which stores energy for later use.
The station also includes over 2,000 sensors based on the Internet of Things technology, and smart metres distributed throughout the facility to monitor power and water demand data in real-time to improve energy and water management. It also aims to reduce demand when required by eliminating non-critical loads through smart lighting, smart power outlets, and smart air conditioning system.
The SGS is also integrated with a smart chiller system through a building management system, and a 100-tonne thermal energy storage system, which stores surplus cooling energy to be used when required, thereby reducing the demand on the smart chiller system.
In November 2015, DEWA signed a contract with KEPCO for the development of the Smart Grid Station at DEWA’s green vehicle workshop in Ruwayyah.
