中文摘要：
按机组发电序位表和等微增率法分配火电机组负荷是国家开展节能发电调度的推荐方法。针对其在实际应用中存在的问题，提出一种考虑出力持续时段约束的火电机组节能负荷分配方法。该方法结合发电序位表设计了动态机组组合算法，灵活地处理持续时段约束，确定最优机组组合方案；采用Kuhn-Tucker最优性条件对等微增率法进行改进，使分配结果满足爬坡及出力上下限要求；对出力变化趋势与系统负荷变化趋势不一致的情况，设计了出力变化趋势修正策略。贵州电网汛期典型日计算表明，所提出的算法具有更好的节能效果，可以更好地满足实际运行要求。
英文摘要：
The sorted table of generating units and equal incremental principle are recommendatory methods for solving the load dispatch problem under energy conservation power generation. However, there are some issues for the practical applications. Hence, this paper presented an energy-saving load dispatch method for thermal unit, which took the durative constraints of generating units into account. The dynamic unit commitment algorithm, which can flexibly deal with the durative constraints and optimizes unit commitment, was designed using generating sorted table. In order to meet the climbing requirements and upper-lower limits of power generation units, the equal incremental principle was improved by using Kuhn-Tucker optimality conditions. The load modifying strategy was introduced to handle the difference of the load changing trend between unit generation and system load. This method was applied as a case study in Guizhou Power Grid, and the results show that the proposed methodology can implement better energy-saving, and better meet actual operation demands.
