Abstract
Renewable energy plays very important role for green-house gas emission reduction and energy security enhancement. More and more distributed generations (DGs) driven by renewable energies will be interconnected in future, however, their volatile and unpredictable generation output may disturb the demand and supply control of power system. Since most of DGs are installed and operated by customers, the demand and supply control should be discussed for both local network and bulk power system. This paper presents recent R&Ds on demand and supply control with massive DG installation.
