摘要：

利用综合能源系统中多能转换协同供能的优势以及蓄冷/蓄热系统的热惯性特点，以实现供能系统故障时的快速恢复供能。分析多能流在各类能源转换设备中转换的功率关系，对各类能源转换设备的输入功率进行控制以实现协同运行，并分析各类能源转换设备的动态响应时间和蓄冷/蓄热设备考虑热惯性时的蓄能容量弹性调节方法，以动态响应时间最短为运行策略的优化目标，实现多能源转换设备故障时供能的优先级及供能功率的优化匹配，得到最终的优化运行策略。算例结果表明，多能协同与储能容量的弹性调节能够快速应对各类场景下的供能故障，实现小时级的供能延长和综合能源系统供能故障时的快速供能恢复。

Abstract:

The advantages of multi energy conversion and coordination energy supply in the integrated energy system and the thermal inertia characteristics of the cold storage/thermal system were considered to realize the rapid recovery of energy supply system when the energy supply system fails.The power relationship of multi energy flow in all kinds of energy conversion equipment was studied.The import power of all kinds of energy conversion equipment was controlled to achieve cooperative operation.The dynamic response time of all kinds of energy conversion equipment and the method of energy storage capacity adjustment with thermal inertia of heat storage and heat storage equipment was analyzed.The dynamic response time were used as the target to optimize the running strategy,and the priority of energy supply and the optimal matching of power supply were realized when the multi energy conversion equipment fails,and the final optimal operation strategy was obtained.The example shows that the resilience of multi energy coordination and energy storage capacity can quickly deal with the energy supply failures in various scenes,realize energy supply extension at the hour level,and realize fast energy supply recovery in the energy supply system for integrated energy systems.

Key words: multi-flow conversion, dynamic response time, thermal inertia, optimization of operation strategy, quick recovery of energy supply failure
