Owing to the potential higher energy supply efficiency and operational flexibility, integrated energy system (IES), including the power, gas, heating, and cooling systems, will be one of the primary forms of energy carrier in the future. However, with the increase of multiple energy devices and systems integration, IES planning is facing a significant challenge in terms of risk assessment. Therefore, a conditional value-at-risk (CVaR) based energy hub (EH) planning model is proposed in this paper. The numerical results illustrate the proposed methodâ€™s effectiveness in balance the potential operation risk and investment cost, while the benefits of introducing energy storage system (ESS) are also verified.
