What's the difference between traditional power grid and smart grid? — From dispatching perspective

Abstract

The development of smart grid requires higher renewable energy penetration as well as power supply reliability and economy. Traditional power grid dispatching cannot meet the demand. This paper analyzes the difference between smart grid dispatching and traditional power grid dispatching from several aspects, including bulk power grid dispatching, small and micro power grid dispatching, interruptible load management and supporting technology for power grid dispatching. This paper expects to make some contribution to a stable, secure, environmentally friendly and resource-saving power grid.
