风电在中国北部地区得到了很大发展，但由于热电联产发电不灵活，大量的风电被浪费，而不是被利用。本文研究了一个由热电联产机组、风电厂和冷凝式电厂组成的一体化热电联产系统，通过将电能存储(EES)和热能存储(TES)相结合，实现了供电侧和供热侧的发电和制热解耦。在此基础上，建立了综合热电联产系统调度(ICHPSD)模型，以达到减少风电削减和一次能源消耗的目标。最后，以六节点系统为例验证了ICHPSD模型的可行性和有效性，仿真结果表明EES比TES对风电并网具有更好的效果。合并EES和TES的年净收益随着透风量的增加而增加，但它们逐渐接近饱和。同时引入EES和TES可以大大增加风电并网量，提高系统的运行效率。
Wind power has achieved great development in Northern China, but abundant wind power is dissipated, rather than utilized, due to inflexible electricity production of combined heat and power (CHP) units. In this paper, an integrated CHP system consisting of CHP units, wind power plants, and condensing power plants is investigated to decouple the power and heat production on both the power supply side and heat supply side, by incorporating electrical energy storage (EES) and thermal energy storage (TES). Then the integrated CHP system dispatch (ICHPSD) model is formulated to reach the target of reducing wind power curtailment and primary energy consumption. Finally, the feasibility and effectiveness of the proposed ICHPSD model are verified by the six-bus system, and the simulation results show that EES has a better effect on wind power integration than TES. The annual net benefits by incorporating EES and TES increase with increasing wind penetration, but they gradually approach saturation. Introducing both EES and TES can largely increase the amount of wind power integration and improve the operation efficiency of the system.
