考虑可再生能源接入的综合能源系统规划评述与展望

建设多能耦合的综合能源系统是解决可再生能源消纳问题的有效途径之一。可再生能源的接入大大增强了综合能源系统的不确定性,如何合理分析并应对不确定性带来的影响是综合能源系统规划研究中的重要课题。文章首先总结了可再生能源接入下综合能源系统的典型结构。然后,梳理了综合能源系统多能负荷预测方法和多能流分析技术的研究成果,进一步从能源站规划、能源网络规划和站网联合规划3个方面归纳总结了考虑可再生能源接入的综合能源系统规划研究进展。最后,从可再生能源消纳新场景探索、考虑可再生能源接入的多能流分析技术、考虑多重不确定性的综合能源系统规划和考虑多能需求侧管理的综合能源系统规划4个角度展望了未来可能的研究方向。

Review and Prospect of Integrated Energy System Planning Considering the Integration of Renewable Energy

The integrated energy system is an effective approach to accommodate renewable energy. Meanwhile, the integration of renewable energy increases the uncertainties of integrated energy systems. To reasonably analyze and deal with the impact of uncertainty is an important issue in the study of integrated energy system planning. Firstly, this paper introduces the typical configuration of integrated energy systems with penetration of renewable energy. Then, current research on multi-energy forecasting methods and technologies of multi-energy flow analysis are illustrated. Furthermore, this paper summarizes the research on integrated energy system planning considering the integration of renewable energy, including energy station planning, energy network planning and joint planning of station and network. At last, the future study directions are prospected from the aspects of new scenes of accommodating renewable energy, multi-energy flow analysis technologies and integrated energy system planning considering multiple uncertainties or multi-energy demand-side management.
