考虑风电-负荷及综合需求响应不确定性的能量枢纽双层优化运行及配置方法
A two-layer optimal operation and configuration method for energy hub considering uncertainty of wind power - load and comprehensive demand response
The existing studies ignore the influence of the uncertainty of integrated demand response (IDR) on the system configuration. Therefore, taking energy hub (EH) as the research object, a two-layer energy hub planning and configuration model is proposed with the uncertainty of wind power output, power load and integrated demand response quantity of electricity/heat comprehensively considered. Firstly, based on kernel density estimation and Copula theory, the joint probability distribution of wind power output-electricity baseline load is established, and typical daily scenarios are generated. At the same time, based on the double uncertainty of baseline load and load elasticity coefficient, a method for calculating the stochastic response quantity of integrated demand for electricity and heat is proposed. Then a mixed integer nonlinear programming model is established with the goal of minimizing the annual operating cost of the system. The example shows that taking IDR into account in the configuration calculation can help to smooth the net load curve of the system, reduce the influence of user energy and intermittent power supply output uncertainty on the system configuration result, and thus improve the system economy.
