of data security – from the beginning to the end of a transmission line, including all products, systems, solutions, and processes – are getting stricter all the time. From our extensive smart grid portfolio, we are providing power suppliers and utilities with the right solutions to meet their needs,” said Jan Mrosik, ceo of the Siemens Smart Grid Division. Te company has also rolled out smart grid remote terminal units for decentralised energy resources. Te Sicam SGU can be used to connect distributed energy resources to a grid control or energy management system by means of communications technology (Figure 2). Used as an input/output (I/O) unit, Sicam SGU allows power companies and public utilities to control and monitor decentralised power generation facilities and power consumers via the smart grid remote terminal unit. In particular, it can be used for bundling decentralised energy sources into a virtual power plant, for demand-response applications, and for setting up micro-grids. Balancing out power generation and power consumption at all times is a bigger challenge for the control system in smart

Smart grid alliance eyes the Middle East S


panish utility Iberdrola plans to join forces with the smart grid division of Siemens in order to win business


in the Middle East. As a first step, the two parties have


signed a memorandum of understanding stating that they intend to negotiate a contract for a strategic alliance. As part of this alliance, the partners plan to develop smart grid technologies for Qatar and then the entire Middle East. Augustin Delgado, innovation,


environment and quality director at Iberdrola, said, “This alliance is an


extraordinary opportunity to introduce successful technological transfer projects to the region, while adding value for customers through the proven experience of two leaders in their respective sectors.” For its part, Siemens says the alliance


will give it the opportunity to better understand its customers’ requirements. Areas in which the partners hope


to cooperate include the integration of energy from renewable sources such as the sun and wind into smart grids. In addition, both companies intend to develop systems designed to balance the


supply and demand for energy (demand response management). Such a balance not only ensures network stability but helps utilities by eliminating the need to draw on expensive peak-load power plants. The two also plan to cooperate


in monitoring and controlling of the distribution grids. Here, new technologies allow for an improved integration of outage management and an advanced level of grid automation. This, they say, will enable utilities to operate their grids more reliably and more efficiently. l
