Smart Grid Tutorial-operations,technologies,companies
This page of tutorials section covers Smart Grid tutorial. It covers smart grid basics, smart grid operations, smart grid technologies and smart grid companies in USA and INDIA.
The term "Grid" refers to a system of high tension cables by which electrical power is distributed throughout a region to provide service to the consumers.
What is Smart Grid?
A smart grid is an electricity network which uses digital and other advanced technologies to manage and monitor transport of electricity from sources to destinations. Sources refer to power generation sources and destinations refer to end users.
The goal of smart grids is to co-ordinate different part of system efficiently as much as possible. It includes grid operators, end users, electricity stake holders etc.
Smart Grid Operations
Figure-1 depicts smart communication based applications.
The Hierarchy of operations are listed below:
• Integrated Utility Business Operation ( Asset management, data warehouse, etc.)
• Added value network management & optimization (applications and systems) such as network planning, meter data management, network information, advanced applications (EMS, DMS, EBM, Trading)
• Network Control and Supervision (Single or multi-utility) such as SCADA etc.
• Communication such as privare and public networks etc.
• Field data acquisition, local control and automation (RTUx, meters, protection etc.)
