水火电力系统短期优化调度模型
|
摘要
构建水火电力系统短期优化调度模型,提出求解思路。从梯级水电站发电量和耗水量、火电机组污染物排放量和发电总成本四方面建立模型;运用满意度函数和欧式距离函数进行归一化处理,结合惩罚函数和双适应度法处理约束条件。将多目标、带约束的复杂优化问题转化为了单目标、无约束的简单优化问题,大大简化了求解过程,提高了算法的收敛速度和精度。充分体现了节能和经济双赢的理念,为水火电力系统短期优化调度提供了新思路。
A short-term optimization scheduling model is established for hydro-thermal power system to propose its solution idea. The model is established from four aspects including power generation capacity and water consumptions of cascade hydropower stations, as well as total pollutant emission and power generation cost of thermal units. Also, normalization is processed through satisfaction function and Euclidean distance function, and constraints are processed by combining penalty function and double fitness method. The complex optimization problem with multiple objectives and constraints is transformed into a simple optimization problem with single objective and no constraint, which greatly simplifies the solving process and improves the convergence speed and accuracy of the algorithm. The concept of winwin between energy conservation and economy is fully embodied, which provides new ideas for short-term optimization scheduling of hydro-thermal power system.
