多类型热电机组群实时负荷动态分配方法

在运行灵活性提升背景下，考虑热电厂内不同类型热电机组的可行运行区间及其相关辅机运行动态安全边界，以实现热电厂整体效益最大为目标，提出一种多类型热电机组群实时负荷动态分配方法。该方法计及热电厂的售电收益、运行成本、辅助调峰市场收益、负荷跟踪惩罚，并通过设置机组出力最小调整量降低各机组出力调整频次。基于东北地区某热电厂实际数据的算例结果验证了所提方法的有效性和优越性。

Dynamic allocation method of real-time load for multi-type CHP unit group

Under the background of improving operation flexibility, a real-time load dynamic allocation method for multi-type combined heat and power unit group is proposed with the objective of maximizing the overall benefit of combined heat and power plant, which considers the feasible operation region of different types of combined heat and power units in the combined heat and power plant and the dynamic safety boundary of related auxiliary machinery operation. The method considers the power sale income, operation cost, auxiliary market income of peak regulation, load deviation punishment of combined heat and power plant, and reduces the output adjustment frequency of each unit through setting the minimum adjustment amount of unit output. The case results based on the actual data of a combined heat and power plant in Northeast China verify the effectiveness and superiority of the proposed method.
