Smart grid- Indian Perspective

  2. 2. Outline of the Presentation Smart Grid Wide Area Monitoring System WAMS Application and Analytics at WRLDC1. Oscillation Monitoring and Analysis2. Angle Measurement3. WAMS and Cloud Computing(c)All Rights Reserved WRLDC,POSOCO
  3. 3. Definition by Wiki A smart grid is an electrical grid that uses information and communication technology to gather and act on information, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.(c)All Rights Reserved WRLDC,POSOCO
  4. 4. Smart Grid - A large "System of Systems” Smart Grid Conceptual Model Bulk Generation Transmission Distribution Customers Operations Markets Service Providers(Source : IEEE Smart grid )(c)All Rights Reserved WRLDC,POSOCO

  6. 6. Distribution Domain Distribution Distributes the electricity to and from the end customers Connects the smart meters and all intelligent field devices, managing and controlling them through a two-way wireless or wire line communications network. It may also connect to energy storage facilities and alternative distributed energy resources at the distribution level.(c)All Rights Reserved WRLDC,POSOCO
  7. 7. Customer Customer Domain The end-users of electricity Connected to the electric distribution network through the smart meters. The smart meters control and manage the flow of electricity to and from the customers and provide energy information about energy usage and patterns. Each customer has a discrete domain comprised of electricity premise and two-way communications networks. A customer domain may also generate, store and manage the use of energy, as well as the connectivity with plug-in vehicles.(c)All Rights Reserved WRLDC,POSOCO
  8. 8. Operations Domain Operations Manages and controls the electricity flow of all other domains in the smart grid. It uses a two-way communications network to connect to substations, customer premises networks and other intelligent field devices. It provides monitoring, reporting, controlling and supervision status and important process information and decisions. Business intelligence processes gather data from the customer and network, and provide intelligence to support the decision-making.(c)All Rights Reserved WRLDC,POSOCO
  9. 9. Markets Domain Markets The Markets domain operates and coordinates all the participants in electricity markets within the smart grid. It provides the market management, wholesaling, retailing and trading of energy services. The Markets domain interfaces with all other domains and makes sure they are coordinated in a competitive market environment. It also handles energy information clearinghouse operations and information exchange with third-party service providers. For example, roaming billing information for inter-utility plug-in-vehicles falls under this domain.(c)All Rights Reserved WRLDC,POSOCO
  10. 10. Service Provider DomainService Provider smart grid handles all third-party operations among the domains. These might include web portals that provide energy efficiency management services to end-customers, data exchange between the customer and the utilities regarding energy management, and regarding the electricity supplied to homes and buildings. It may also manage other processes for the utilities, such as demand response programs, outage management and field services. (c)All Rights Reserved WRLDC,POSOCO
