摘要

风电出力的不确定性给电力系统规划与优化运行带来较大挑战。对火电机组进行灵活性改造能有效提升电力系统的灵活性、促进风电的消纳。文中利用盒式约束与1-范数约束对不确定风电出力进行建模，考虑火电机组的灵活性改造技术优势和经济耗费，从电力系统价值整体提升的角度出发，建立了以投资费用与系统运行成本之和最小为优化目标的电源弱鲁棒优化规划模型。所提模型改善了传统鲁棒规划模型的保守度，提升了规划方案的经济性。以改进的IEEE-RTS24节点系统与区域电网实际系统对所提模型进行仿真分析，算例结果验证了所提模型的鲁棒性与经济性。

Abstract

The uncertainty of wind power output brings great challenges to the planning and optimal operation of power system. The flexibility reformation of thermal power units can effectively improve the peak regulation capacity of the power system and promote the accommodation of wind power. The uncertain wind power output is modeled by box constraint and 1-norm constraint. By considering the technical advantages and economic cost of the flexibility reformation of thermal power units

from the perspective of the overall value of the power system

and based on the light robust optimization theory

a generation expansion planning model with the minimum sum of investment cost and system operation cost is established. The proposed model improves the conservative degree of the traditional robust planning model and improves the economy of the planning scheme. The improved model is analyzed in the improved IEEE-RTS24 node system and an actual system of a regional power grid. Results of the example verify the robustness and economy of the proposed model.
