Abstract：The paper researches the large consumer’s power purchase problem from different markets and analyzes the optimal purchase portfolio based on expected profit and risk. The optimal purchase model is established, which takes the maximum expected profit and minimum spectral risk considering large consumer’s subjective risk aversion. Calculation results show that the spectral risk method is more flexible and practical compared with VaR and ES, without setting the confidence level previously. The large consumers can choose spectral risk freely according to the degree of risk aversion. Meanwhile, the proposed model provides the large consumers a decision way of purchase proportions from different markets and risk valuation.
