摘要
根据风电供热项目的基本原理,建立了包含基本制热、蓄热制热和蓄热三个模块的通用数学模型,并构建了风电供热与弃风协调的灵活运行策略;在此基础上,建立了计算风电供热项目节煤效果、国民经济性的数学模型,提出了确定项目最佳配置方案的方法;并进一步基于实际风电数据,分析了风电弃风特性及其对风电供热项目的影响。算例比较了固定时段运行策略与协调运行策略消纳弃风的效果,对比了纯蓄热电锅炉供热方案和含热泵蓄热供热方案的优劣,分析了两种方案的经济性及其影响因素,给出了一些有意义的结论。上述研究可为风电供热项目的规划运行提供参考。
According to the basic principle of the wind power heating project, a general mathematical model including basic heating module, storage heating module and heat accumulation module was established, and a flexible operation strategy was proposed to coordinate three modules＇ operation according to curtailed wind power. Then, based on the analysis of the wind power curtailment characteristics, a mathematical model was developed to calculate the coal-saving performance, national economy and the optimal configuration of the wind power heating project. Furtherly, wind power curtailment characteristics and its impact on wind power heating project was analyzed. Based on the practical data, the example compares the performance on wind power accommodation between the fixed time operation strategy and the coordinated operation strategy of heating project, contrasts the pure electric boiler scheme with heat pump included scheme, analyzes the economy and its impact factors of two schemes. Finally, some meaningful conclusions are given which can provide reference for planning and operation of wind power heating project in the future.
