Robust Optimal Dispatch of Regional Power Grid Considering Flexible Resources on Both Source and Load Sides
In view of the increasing trend of renewable energy generation and flexible resources in the power grid,a robust op-timization method for day-ahead dispatching considering the flexible resources of both source and load sides is proposed to cope with the challenges brought by the uncertainty of renew-able energy generation to the dispatching operation of the power grid.Firstly,according to the response characteristics of reducible loads and shiftable loads,the influence of compensa-tion price on the maximum reduction capacity of the former and the acceptable translation period of the latter is analyzed,and the flexible resources model of load side is established.Secondly,considering the uncertainty of wind power output,based on the model of deep peak regulation and flexible re-sources on load side,a robust optimization model for day-ahead dispatching is established,in which the compensation price and adjustment quantity of flexible loads are jointly optimized.Fi-nally,the effectiveness of the proposed model and method is verified by an example analysis.The results show that the dis-patching method considering the schedulable potential of flex-ible resources of both source and load sides can effectively im-prove the robustness and economy of power grid operation.
