摘要
以东北地区某1 100 MW电厂进行示范验证,研究了新型电网调度模式下的电厂负荷分配问题。基于机组特性和电网调峰补贴政策建立了全厂的经济性收益评估模型,并结合热力系统映射模型和智能优化算法,形成面向多能源发电协同控制模式的多机组热电负荷分配实时优化方案和日前优化方案。研究结果表明:基于实时优化方法获得的负荷分配方案在7种历史工况下可以实现11.56%~33.94%的经济性提升;日前优化方法相比于实时优化可以进一步提升电厂的经济性,在所选取典型日场景中可提升28.07%;有效解决新型电网调度模式下电厂内负荷分配的难题,为运维人员的决策提供指导。
A demonstration verification was conducted on a 1100 MW power plant in Northeast China to study the load distribution problem of the power plant under the new power grid dispatching mode.Based on the unit characteristics and grid peaking subsidy policy,a plant⁃wide economic revenue evaluation model was established,and combined with the thermal system mapping model and intelligent optimization algorithm,a real⁃time optimization scheme for multi⁃unit cogeneration load distribution and a day⁃ahead optimization scheme for multi⁃energy generation cooperative control mode were formed.Results show that the load distribution scheme obtained by real⁃time optimization method can achieve an economic improvement of 11.56%to 33.94%under 7 historical working conditions;the day⁃ahead optimization method can further improve the economics of the plant compared to real⁃time optimization by 28.07%in the selected typical day scenario;the method can effectively solve the difficult problem of load allocation within the power plant under the new grid dispatching mode and provide guidance for the decision making of the operation and maintenance personnel.
