考虑信息间隙决策的能源枢纽混合储能容量规划OA北大核心CSTPCD

Aiming at the problem that conventional energy storage such as battery energy storage cannot quickly re-spond to the short-term disturbance of wind power output of the energy hub,this paper introduces hybrid energy storage into the energy hub,considers the loss of hybrid energy storage in the operation of the hub,and puts for-ward the energy storage capacity planning model when the daily operation cost of the energy hub is optimal.Then,based on the information gap decision theory(IGDT),under the risk aversion strategy and opportunity seeking strategy,a robust and opportunity model considering the uncertainty of wind power output is established,which pro-vides decision makers with energy hub capacity planning scheme.Finally,through the example analysis,it is proved that the energy hub using hybrid energy storage has higher storage and conversion efficiency of wind power output and less daily operation cost.At the same time,the hybrid energy storage capacity planning model based on IGDT can provide decision makers with the maximum/minimum fluctuation range of wind power output when meet-ing the expected operation objectives.The relationship between wind power output uncertainty and hybrid energy storage capacity is analyzed,which provides capacity planning basis for different risk preference strategies through quantitative analysis.
