In order to control the risk of power spot market price fluctuation on the operation benefit of virtual power plant, the transaction risk of virtual power plant operator is studied, and the virtual power plant declaration strategy considering spot transaction risk is proposed. The fluctuation of spot market price may cause the profit change or even loss of virtual power plant. According to the expectation of market price fluctuation, the expected risk constraint of virtual power plant based on conditional value at risk is established to ensure that the transaction risk of virtual power plant declaration strategy is within its tolerable range. On this basis, a virtual power plant spot market declaration strategy model considering transaction price risk is proposed. The model optimizes the maximum expected return and considers the constraints including expected risk constraints. Finally, an example is constructed based on the actual data of a virtual power plant to verify the effectiveness of the proposed method.
