兼顾电力市场竞价的区域电网节能发电调度模型

Research on energy-saving generation dispatching model in regional grid considering bidding mechanism

分析了区域电网节能调度和电力市场竞价的目标函数和约束条件,发现两者具有相同的数学模型和相近的目标函数。在此基础上,提出了一种兼顾电力市场竞价的区域电网节能发电调度模型。针对此数学模型,给出了采用先分省排序,然后省间撮合替换的区域电网发电调度算法。最后通过实例计算进行了不同的模式间的节能情况、购电成本和跨省交易情况比较分析,证明了兼顾市场竞价的区域电网节能发电调度模型具有很好的节能、降低购电成本,优化资源配置的作用。

This paper analyses the target function and constraints of energy-saving generation dispatching and bidding transaction in regional grid. And it is found that the two mechanisms have the same mathematical mode. Then an energy-saving generation dispatching model in regional grid considering bidding mechanism is proposed. After that the paper gives an algorithm to solve the model which is sequencing the units in each province following with trans-provincial alternative. Analysis and comparisons of coal cost, purchasing cost, as well as trans-provincial transaction are made on different mechanisms using the real data. The results reveal the positive signification of the proposed mode in energy saving and purchasing cost decreasing.
