The combined optimization model of purchasing and selling power based on CVaR

The core business of the electricity selling company is the purchase and sale of electricity. Through load combination optimization and mining of users' power consumption characteristics, power selling companies can obtain high-quality user groups, understand the various power consumption characteristics of users, so as to forecast load demand, and provide differentiated tariff packages for different user groups as the basis for purchasing and selling power decisions. Therefore, this paper sets up models for the cost of power purchase of the power selling company and the revenue of power selling considering the utility of power consumption of the user respectively, and finally establishes a joint optimization model of power purchase and sale based on CVaR to measure the risk. The effectiveness of the proposed joint optimization model is verified by numerical simulation.
