Implementation strategies for migration towards smart grid

The power grid of the future will be more internet-like grid, with multidirectional flows of data and energy from central and distributed generation plants. Concept of smart grid is a “super” network connecting to the national power grid, the market, consumers and generation with intention to optimize the overall process. The basic concept of smart grid is to add monitoring, analysis, control and communication capabilities to the national grid in order to maximize the system output while reducing energy consumption. smart grid technology can improve the reliability, security, and efficiency of the electrical grid as intelligent devices can automatically adjust system response to changing conditions to prevent blackouts or increase capacity. How we will know when smart grid has arrived? Partly we already have smart grid. All the components, IEDs, applications, communication, and solutions are in the marketplace, some of them is already installed and implemented. What's mainly missing is coordination that holds all the pieces together. What do we really need to realize the idea of smart grid? Primary requirement for any utility is to provide the right information to the right persons at the right time. Traditionally, the operating data needed for a consolidated view of the grid and adequate decisions, are stored in separate systems and isolated to different business units. Uniform standards will simplify new equipment selection and installation. At the moment lack of standards and increased upfront cost hinder the deployment of smart grid technologies. Utilities already have invested substantial sum of money in good, solid, well-linked applications, control systems and adequate communication. Therefore, smart grid must work seamlessly with most of a utility's existing applications and future expansions. It must combine data from multiple sources in order to make dynamic grid management decisions. Smart grid will be different for every utility. This article deals with technologies already used by utilities in order to recognize those that could be a part of smart grid and smart grid required infrastructure for collection and management of time series data. Also mentioned will be the importance of cyber security and suggestions on how to add coordination, communication and control capabilities to the existing equipment, systems and applications that will optimize the operation of the grid as well as constraints in implementation of smart grid vision. Paper will suggest implementation strategy to support the migration and evolution of existing systems in transmission network towards smart grid.
