Abstract: This paper takes the method of load source duality modeling for active demand response as the theme, analyzes the research results of load source duality modeling at home and abroad from the perspective of flexible resources participating in grid dispatching on demand side. According to the research object division, LFG (load follow generation) model is divided into general load, energy storage equipment, distributed energy and its combination, and it can model and optimize load response The paper expounds the target, constraint, scheduling method and control mode, and expounds that the load following generation mode can realize the active demand response, optimize the load curve, alleviate the dispatching pressure on the power generation side, and promote the consumption of renewable energy.

Key words: demand response(DR), load aggregation, load-generation duality, flexible load, flexibility
