The Impact of Demand Response on Economic Scheduling Models
The introduction of the electricity market makes the traditional economic dispatching model unable to meet the current dispatching requirements,thus introducing a demand response mechanism in the market competition,so that it can coordinate the generator set and the load to complete the economic deployment,to ensure the system stability and maximize economic benefits.Based on the above background,this paper has done the following research on related issues:Firstly,the paper introduces the economic dispatching model under the traditional mode.The linearized generator cost function is the optimization target,and the model is established considering the conditions of power balance and line safety constraints.The three-machine three-node system is used to solve the problem.Secondly,considering the use of interruptible load as a system backup,it is equivalent to the virtual unit in the power plant,and it is modeled with reference to the model of the conventional unit.Finally,on the basis of the traditional economic model,the interruptible load is added,and the sum of the interruptible load and the unit cost is minimized.The conditional constraints are updated,and the fault is simulated according to the definition of the interruptible load.The results analyze the impact of interrupted load on economic dispatch.In summary,through modeling and example analysis,this paper concludes that the introduction of demand response makes system scheduling more flexible,and enhances demand side elasticity and system stability.
