Abstract： New energy power generation technology has the advantages of energy saving and environmental protection.However， wind and solar energy have intermittent power generation and poor power supply stability， resulting in frequent fluctuations in grid load.  At the same time as their rapid development， cogeneration units continue to grow and heat supply The contradiction with power supply is prominent， and the difficulty of peak shaving during the heating period has intensified， causing the pressure of peak shaving of the power grid to continue to increase， and the situation of new energy consumption is becoming increasingly severe. Now we mainly discuss the flexible transformation of coal-fired cogeneration unit to adapt to the deep peak shaving market technology， and make reasonable plan selection.

Key Words： New energy power generation; Coal-fired cogeneration unit; Thermoelectric  coupling; Deep peak shaving; Flexible transformation technology

作為十四五开局之年，“3060目标”加速进行。我国碳排放结构中，火电是减碳的主要领域。在电力能源结构中，我国仍以火电为主，基于我国节能减排政策的引导，我国可再生能源的开发利用仍有很大的空间，随着新能源发电在我国电力能源结构中的占比日趋加大，煤炭消费压减和清洁能源利用比重提高将成为长期发展态势。新能源成为电力供应主体必将成为电力市场核心特征。

新能源发电技术具有节能和环保的优势，但风能和太阳能具有间歇性发电、电力供应稳定性差，引发电网负荷的频繁波动，风电和光伏的消纳形势日趋严峻，已出现严重的弃风、弃光现象，新能源发电入网占比严重偏低【1】。同时，热电联产机组持续增长，供热和供电的矛盾突出，供热期调峰困难加剧，使得电网调峰压力持续增大，这对电网中的发电主力燃煤电厂中的热电联产机组调峰能力提出了新的要求及考验。……
