Integration of flexible and controllable load resources into power system scheduling and operation will enrich scheduling modes and enhance the system regulating capability

which has become a worldwide research hotspot. This paper is intended to make a review of recent investigations on the adjustable potential

scheduling modes

response behavior modeling and scheduling frameworks of flexible loads considering demand response (DR). Then detailed light is shed on the advantages and problems of these scheduling modes and scheduling frameworks. By proceeding from five aspects including modeling of flexible load’s comprehensive response

multi-time scales interactive trading modes

multi-time scales coordinated scheduling

coordination of centralized control and decentralized control

interactive benefit assessment

further research directions for flexible load scheduling are discussed. In addition

in view of China’s actual situation

suggestions for and assumptions about developing flexible load scheduling are proposed.
