【摘要】：为了消除用于评价电力网络规划方案的同类指标之间存在的关联性,提出一种基于Choquet容度积分的规划方案综合评价方法。首先利用Choquet容度的非可加测度特性对不可加的关联指标进行测度,然后应用Choquet积分求取综合评价结果以消除指标间的关联性。经济性评价容纳了不同决策者面对电力网络投资收益不确定时的风险态度/偏好,需要采用合适的效用函数来描述决策者的风险偏好,该文采用基于Choquet积分的风险溢价来度量决策者为消除风险愿意减少的回报量,然后将求得的已考虑风险偏好的决策者主观预期综合收益作为经济性指标的综合评价结果。针对经济性和可靠性评价指标,建立了电力网络规划方案评价决策表。算例结果表明,所提出的方法可以对电力网络规划方案进行合理评价。
[Abstract]:In order to eliminate the correlation between the same indexes used to evaluate power network planning schemes, a comprehensive evaluation method of planning schemes based on Choquet capacity integral is proposed. Firstly, the non-additive measure of Choquet capacity is used to measure the non-additive correlation index, and then the comprehensive evaluation result is obtained by using Choquet integral to eliminate the correlation between the indexes. The economic evaluation takes into account the risk attitude / preference of different decision makers in the face of uncertain investment returns in power network, so it is necessary to use appropriate utility function to describe the risk preference of decision makers. In this paper, the risk premium based on Choquet integral is used to measure the amount of return that the decision maker is willing to reduce in order to eliminate the risk. Then, the subjective expected comprehensive income of the decision-maker who has considered the risk preference is used as the comprehensive evaluation result of the economic index. According to the evaluation index of economy and reliability, the evaluation decision table of power network planning scheme is established. The results show that the proposed method can evaluate the power network planning scheme reasonably.
