市场背景下考虑不确定性价值和全市场要素博弈的电力系统规划方法

Power system planning method considering uncertainty value and entire market element game under market background

电力市场化改革的深化为电力系统规划领域引入了新的问题。为应对这一变化,提出了一种市场背景下考虑规划不确定性价值和全市场要素博弈的电力系统规划方法。首先,在分析电力市场各参与者的整体利益诉求的基础上引入特殊主体独立系统运营商(Independent System Operator,ISO),并从市场运营角度构建输电公司规划模型。然后,在RO(Real Option)理论的基础上,以发电机组选址定容、输电线路扩容和分布式电源(Distributed Generation,DG)投运为决策变量,并同时分析各市场参与者之间的博弈交互机理,构建基于RO理论的多主体博弈规划模型。基于IEEE30系统的仿真算例验证了所提方法的有效性和正确性。

The deepening of power market reform has introduced new problems to the field of power system planning.To cope with this change,a power system planning method considering the uncertainty value of planning and the game of entire market factors under a market background is proposed.First,an independent system operator(ISO)is introduced based on the analysis of the overall interests of participants in the power market,and the planning model of transmission companies is constructed from the perspective of market operation.Then,the location and capacity of the generator set,transmission line expansion,and distributed generation(DG)operation are taken as decision variables,and the game interaction mechanism between market participants is analyzed.A multi-agent game planning model based on RO theory is constructed.Simulation results based on the IEEE30 system verify the effectiveness and correctness of the proposed method.
