    Deregulation and liberalisation of energy markets are spreading rapidly over the entire globe. This process is changing the business environment in all sectors of power companies: generation, transport, distribution and sales, with dramatic impact on the way the traditional utilities do business. Competition is placing pressure on utilities to cut their costs. Only companies that are really determined to go ahead and exploit their potential to the utmost will be successful in the long run. More intensive and efficient use of information systems is the key factor to success. It is evident that IT will play a major role for success in rapidly changing and strongly competitive markets. The article discusses the impact of deregulation on the IT solutions required to achieve this goal. As practical examples, some applications and current developments at Siemens are used.

    Deregulation and competition in the electricity industry, and power generation in particular, have brought about a need for flexibility, reliability, increased automation and cost minimisation in generating plants. To stay competitive, power plants will need to operate optimally all of the time, requiring the exploitation of advanced control and optimisation strategies. Although most power plants are a 'single product' (electricity) manufacturer, in comparison to, say, petrochemical plants, there are still opportunities to learn from and to adapt some of the advanced control technologies that these multi-product industries use, e.g. multivariable control, model-based predictive control, neural networks, etc., for use in power plants.

    The commercial risks in providing services or products in the energy business require design engineers to provide low-risk solutions to arising problems that can be implemented in the shortest possible time. Maintaining plant availability is paramount, and hence any solution must minimise prolonged exposure to the fault and prevent disruption to commercial operation. The tendency is to rely on existing knowledge; hence, control system design features usually employ established techniques rather than incur undue risk. This article describes an engineering approach to providing a control system solution to a number of remote gas turbine installations that developed instabilities within their combustion systems. To fully understand the causes of these instabilities required a service introduction of both a practical and robust control solution to meet the customer expectations. In addition, remote access to the installations to retrieve data and monitor the control system was essential in solving this problem. View full abstract»

    A range of advanced simulation tools is now available which facilitates the modelling and analysis of complex systems. The authors' companies have been utilising the versatility of two such products to simulate a complex industrial combined heat and power (CHP) plant. The potential benefits include improvements in the plant design, control system design and in-process operation. This article describes two projects where the specialised power plant simulation tool ACSL/MMS has been used. In the second project, MATLAB/SIMULINK was used to analyse and undertake control design studies on power plants originally simulated using ACSL/MMS. View full abstract»

    Engineers within the electrical power industry are becoming increasingly challenged by the volume of data that must be analysed. In reality, they are interested in the significant information that can be interpreted from the data. Intelligent systems are seen as a solution to this problem, as they are able to interpret data to provide information, thereby offering decision support. This article discusses the use of intelligent systems for decision support applied to power system control and management. View full abstract»

    A variety of authentication methods to verify the identity of valid users can be implemented with IPSec (IP security), including shared secret, token cards and digital certificates. For a large extranet implementation, the easiest method is public key infrastructure (PKI) using digital certificates. This article gives telecommunications managers, network planners and engineers a more detailed look at how PKI works in a virtual private network (VPN) environment. View full abstract»
