Energy Saving in Smart Grid

Power demand is increasing gradually and micro-grid dispatch is the important scheme to stable grid operation. It is not easy to build or extend unclear energy in Taiwan and there are the challenges about the pollution issues when making lots of thermal power generations, such as coal-fired power plants, will have carbon emission pollution problems. For increasing power generations, renewable power and hydroelectric power are increased to supply power to grid for dispatching due to concerning pollution reason and supply power shortage in peak time. In smart grid, energy saving is the key point about energy policy. Therefore, advanced metering infrastructure, smart meter, is the core competence to smart grid in energy saving and power dispatch. Smart meter solution with time of use rates, demand response, and aggregator with load shedding applications can help grid dispatch in power forecast precisely and avoid peak time power demand shortage. Energy saving definitely is the development target in the world trend about power system, so smart grid in energy saving analysis is this paper contribution to comprehend and enhance grid stability and reliability.
