热电同调策略下冷热电联产系统的运行方案优化

Research on Optimal Operation Scheme of CCHP System with Dual-Gas Turbines under Different Operation strategies

针对某综合社区的可调回热燃气轮机冷热电联产系统(CCHP),应用Ebsilon软件搭建了系统仿真模型,研究在热电同调运行策略下,以年净运行收益为目标的联产系统优化运行问题。研究结果表明:在不引入分产设备和储能设备的前提下,通过调节燃气轮机回热度和燃气轮机发电量,可以实现联产系统的热电同调;对于确定的燃气轮机联产系统,热电同调的范围是有限的;研究的CCHP系统在给定的市场条件下,热电同调运行策略与以热定电运行策略相比,全年净运行收益提高了5.23%。

A simulation model for a CCHP system with adjustable heat recovery gas turbine of a comprehensive community was established by Ebsilon software, and the optimal operation of the CCHP system with the goal of annual net operating income was studied under the operation strategy of Thermoelectric Ratio Adjustable.The research results show that, without separate production equipment and energy storage equipment, the CCHP system can realize the Thermoelectric Ratio Adjustable operation strategy by adjusting the gas turbine heat recovery and the gas turbine power generation.Under the given market conditions, the annual net operation income under the operation strategy of Simultaneous Thermo-Electric Regulation is 5.23% higher than that with the operation strategy of Heat Following.
