摘要
建立电力市场的目的是在电力工业引入竞争机制,通过竞争提高发电厂商的生产效率,降低发电成本。以单元机组为研究对象,基于运行数据计算获取的单元机组能耗特性曲线,建立了负荷优化的目标函数及对应的约束方程。以某厂6台机组运行数据为基础,通过优化算法实现电厂内机组间负荷的最优化分配,并对基于等微增率法、复合形法2种不同优化算法计算结果对比分析。
To build the power market is for introducing competition mechanism in power industry, improving the production efficiency and lowering the power generation cost. According to the energy consumption characteristics curves gotten from operation data, the load optimal objective function and the restrained equation were constructed for thermal power unit. Based on the operation information of six units in one power plant, the optimum dispatch was realized among those units by using optimal algorithm, and the results, which were calculated by equal - microinereas rate method and complex method, were compared and analyzed.
