Purchase and Sale Strategies for Power Retailers Considering Risks

Abstract

Renewable energy has become one of the sources of purchase for power retailers in the power market, due to its low cost and environmental protection. It is important to analyze the business risks brought by various uncertainties for the power retailers during the process of purchase and sale of renewable energy. Aiming at the diversity of market combinations and a series of uncertainties with the market, a multi-objective optimization model of purchase and sale for power retailers considering risks was established in this paper by coordinating the profit and risk of purchase and sale based on the theory of risk element transmission. The example showed that the strategy proposed by this paper can provide decision-making reference for power retailers and promote the consumption of renewable energy.
