Integration of flexible and controllable load resources into power system scheduling and operation will increase the risk of grid congestion, and pose new challenges to power system dispatching regulation ability. The traditional power grid eliminates congestion mainly through capacity-increase, load transfer and orderly power utilization. With the upgrading of the interactive capabilities of “source-grid-load”, flexible loads participating in grid scheduling plays a very cost-effective role in solving grid congestion problems. Based on flexible loads involved in demand response scheduling, a comprehensive optimal scheduling model for integration of power generation and consumption considering network constraints is developed to make comprehensive benefits of interaction maximum. By forming the optimal pricing and incentive scheme, the model realizes coordinated scheduling of the integration of power generation and consumption. On the basis of effectively mitigating grid congestion, it has optimized the satisfaction and interaction costs. The optimization model is proved economical and effective with the example of an IEEE14-node system.
