What is Solid State Transformer (SST)

A solid state transformer (SST) alternately known as “smart transformer,” is a modern electrical energy device that offers bi-directional power flow. It is an amalgamation of high-powered semiconductor components, control circuitry and conventional high frequency transformers, offering reactive power compensation, harmonics reduction, and many others.  Solid state transformers cater to a wide variety of applications, ranging from alternative power generation to traction locomotives, power grid and electric industries, and others.

Advanced Metering Infrastructure (AMI)

Advanced Metering Infrastructure (AMI) is seen as the modernisation of the electric, Gas and water metering infrastructure to one that is more connected. This is the use of smart meters and other communication solution combine as as part of one network infrastructure to allow data from from customers' premises to the utility and visa versa.  Often times the upgrade to advanced metering represents the starting point for a broader set of smart grid initiatives, such as distribution automation.

Home Area Network (HAN)

HAN is a network of energy management devices, consumer electronics, signal-controlled appliances, and applications within a home. It is the communication capability within a home. HAN specifications include Zigbee, HomePlug, Z-Wave, and Wireless M-Bus. Instead of a network of servers and computers, HAN connects devices that are capable of sending and receiving signals from a meter, in-home displays, and HEM applications.

Demand Response Management System (DRMS)

Demand Response Management System (DRMS) plays a key role in the implementation and and management of smart electricity. IT is the software technology platform that helps the utilities, energy retailers, and suppliers in implementing demand response (DR) programs using an integrated system, connected to the commercial, industrial and residential premesis.  The platform allows utilities to get real-time customer usage data via the smart meter installed at the cusomter site.
