含风电场的电力系统环保经济调度研究

在节能减排的电力市场环境下,清洁能源发电因其发电成本较低,环境污染小,而具有日益重要的地位。本文研究风电接入系统后的电力系统动态经济调度,建立了含风电场的环保经济调度数学模型,提出以系统总发电成本最低为目标函数,并考虑常规火电机组和风电场的各种约束条件。根据某地区的实际负荷数据,利用搜索能力强、寻优速度快的粒子群优化算法进行仿真验证,结果表明数学模型与优化算法的正确性与有效性。最后,应用相对熵均衡性理论,对优化调度的决策结果进行评价与选择。

Research on environmental economic dispatch of power system including wind farm

In power market environment with energy conservation and emission reduction, clean energy power has an increasingly important position because of its low cost and environmental pollution. In this paper, power system dynamic economy dispatch including wind system is sdudied. The model of environment economic dispatch including wind power is established with the lowest generating cost of total power system as the objective function. The various constraint conditions are considered with conventional thermal po...
