With the increase in clean energy penetration, its power curtailment during operation is made increasingly evident. In this circumstance, it is imperative to address the conflict between inflexible combined heat and power (CHP) units and variable wind and solar power. In this paper, a novel coordinated optimal operation strategy of a district energy system with CHP, wind power and energy storage is established with the following characteristics: the optimal installed capacity of electric energy storage (EES) is determined to smooth the high frequency fluctuation of wind power generation; the CHP units achieve dynamic response to wind power ramp events timely after EES smoothing; and the CHP model with start-stop and dynamic response mechanism is able to reduce the installed capacity of electric boiler (EB) significantly. One-week operation data is adopted in the case studies to increase the reliability of simulation results. The simulation results show that with EES integration, high frequency wind energy curtailment is reduced, the capability of peak regulation and power ramp of CHP units is enhanced by start-stop and the proposed dynamic response mechanism and environmentally sustainable and socially resilient cities is promoted.

随着清洁能源渗透的增加，其在运行期间的功率缩减变得越来越明显。在这种情况下，必须解决刚性的热电联产（CHP）单元与可变的风能和太阳能之间的冲突。本文提出了一种具有以下特征的具有热电联产，风能和储能的区域能源系统的协调最优运行策略：确定最佳储能装机容量（EES），以消除电网的高频波动。风力发电；热电联产机组在EES平滑后及时获得对风电斜坡事件的动态响应；带有启停和动态响应机制的热电联产模型能够显着降低电锅炉的装机容量。案例研究采用了一周的运行数据，以提高仿真结果的可靠性。仿真结果表明，通过EES集成，减少了高频风能的削减，通过启停提高了CHP机组的峰值调节能力和功率斜坡，并促进了拟议的动态响应机制和具有环境可持续性和社会抗灾力的城市。
