Energy Management System in Smart Grid: An Overview (original) (raw)

The rapid economic development is causing huge stresses in the existing generation, transmission and distribution systems as they are not able to keep pace with the increasing demand. Installation and incorporation of a large number of electrical power generation units with increased capacities to deal with the surging demand has an adverse impact on the environment therefore an efficient Energy Management is imperative. Smart Grid may be the answer to this expected energy crisis and management. Conventional instrumentation has proven inadequate for the purpose of managing the extensive and complex power systems. The electric grid to increase overall system efficiency and reliability. Much of the technology currently in use by the grid is outdated and in many cases unreliable. The smart grid implements a two way communications and also facilitate the two way flow of energy. A smart grid is an intelligent electricity network that integrates the actions of all users connected to it and makes use of advanced information, control, and communications technologies to save energy, reduce cost and increase reliability and transparency. Smart Grid has two major aspects, the smart grid (Generation, transmission and distribution system) on one hand and programmable smart appliances on the other. This review paper presents literature survey conducted on different energy management systems fetching the data from the generation to consumption by using different means and approaches. The Smart Energy Management System is developed with ability to record, store, and process power consumption data of every major appliance in the house and Industries. The power consumption data is accessible through the Web portal and on handheld devices. Homeowners and Industries can track their power usage by device, room, equipment, Plant or appliance, which helps better regulate power consumption. In this article, we survey the literature till early 2015 on the enabling technologies for the Smart Grid. Out of three major systems, namely the smart infrastructure system, the smart management system, and the smart protection system, We explore the energy management system(EMS). Again out of various management objectives in smart management system, such as improving energy efficiency, profiling demand, maximizing utility, reducing cost, and controlling emission we explore to integrate home and building energy management systems (HEMS, BEMS), solar PV technology, and energy storage with the microgrid.
