| 中文摘要:综合能源系统是泛在电力物联网的重要组成部分，多种类型的储能设备在其中发挥了重要作用。目前的多数研究只考虑了单一类型电储能对综合能源系统优化运行的影响，或是通过对多种能量形式的储能进行联合优化调度展开研究。至于多种类型电储能在综合能源系统中的优化运行结果以及定量对比分析工作还开展的较少。鉴于此，文中提出了计及飞轮储能、电化学储能和超导储能等多类型电储能的综合能源系统优化运行模型，以系统日运行成本最低为目标，并采用人工智能算法来保障预测数据的准确性，利用混合整数线性规划方法进行求解，同时设置了3种运行场景，对不同场景下的优化结果进行了定量分析对比。算例分析表明，采用电化学储能可获得最低的系统运行成本以及最为显著的售电交易量；而超导储能具备充放调度灵活性高，充放潜力大的特点。 |

| Abstract:The integrated energy system is an important part of ubiquitous electric Internet of Things and various types of energy storage equipment play an important role in the operation of the system. However, most of the current studies in this field only consider the impact of a single type of electrical storage on the optimal operation of the integrated energy system, and there are some studies which are conducted through the joint optimal the dispatch of multiple energy forms of energy storage. Little has been done in the aspects of the optimal operation results and quantitative comparative analysis of multi-type electrical storage in the integrated energy system. In view of this situation, this paper proposes an optimal operation model of the integrated energy system considering various types of electrical storage such as flywheel energy storage, Electrochemical energy storage and superconducting energy storage, with the goal of minimizing the daily operating cost of the system. The artificial intelligence algorithm is adopted to ensure the prediction accuracy and the mixed integer linear programming method is used to solve the optimal operation problem. At the same time, three operating scenarios are set up, and the optimization results under different scenarios are quantitatively analyzed and compared. The results show that the lowest operating cost and the most significant transaction volume can be obtained by electrochemical energy storage while superconducting energy storage has the characteristics of high flexibility and great potential in charge and discharge. |
