Abstract Combined heat and power (CHP) units, as integrated power and heating systems, aim for the flexibility of the electric system and efficiency of the heating system. In this study, the static and dynamic models for CHP units are presented, and a novel control strategy for heat and power coordination and distribution is proposed based on the design of heat-to-power support, heat state reconstruction, and accurate energy balance. Simulation results of a 300 MW CHP unit prove that the proposed strategy improves the unit power load-following capability and meanwhile ensures reliable heat supply.

基于热电估算与协调的热电联产机组柔性控制

摘要 热电联产（CHP）机组作为一种电力和供热一体化系统，旨在提高电力系统的灵活性和供热系统的效率。在这项研究中，提出了热电联产机组的静态和动态模型，并基于热电支持、热态重构和精确能量平衡的设计，提出了一种新的热电协调和分配控制策略。一台300MW热电联产机组的仿真结果证明，该策略提高了机组功率负荷跟随能力，同时保证了可靠的供热。
