【 摘 要 】
In order to enable demand side resources effectively participate in the operation of the system, an abstract recognition model of small demand response resource is established which extracts the key parameters such as rated capacity, load fluctuation characteristics and demand response characteristics to help the power system understand more easily. Considering the influence of small load fluctuation and response characteristics, general aggregation and complementary aggregation models are established. An economic dispatching model considering aggregate's dynamic adjustment potential was established where the aggregate with the lowest power generation cost was selected and a load scheduling strategy was developed. The results show that the proposed model can effectively reduce the cost of power generation. It demonstrates that the demand-side resource dynamic aggregation which considers load fluctuation may conductive to the safe and economic operation of the system.
