摘要
以"零排放、无污染"的新能源发电替代化石能源发电,是解决当前环境及能源问题的主要途径。构建了考虑脱硫、脱硝等环境成本以及网络传输约束的风-火联合发电发电调度模型,在保证电网安全运行的前提下,既降低SO2、NOx的排放,同时提高风电上网规模。该模型以系统运行成本最小为目标,在传统风电经济调度基础上,综合考虑火电机组成本、环境成本、风电运行成本以及网络传输约束等因素,通过改进遗传算法对模型进行求解。最后以IEEE-30节点6机系统为例,对传统风电调度方法和本文方法进行了比较分析,验证了该模型的有效性和合理性。
Renewable power generation of ＂zero emission and no pollution＂ instead of fossil power generation is the main approach to solve environment and energy issues.A combined dispatching model of wind and thermal power generation was constructed considering environmental cost and network constraints in this paper.The model could ensure power grid safe operation,reduce emissions of SO2 and NOx,and increase wind power accommodation.It took the minimum system operation cost as objective,based on traditional economic dispatching of wind power and considering thermal unit cost,environmental cost,operation cost of wind power,network transmission constraints,etc.The model was solved with an improved genetic algorithm.Taking IEEE 30-node 6-machine system as an example,the method was compared with traditional method,proving validity and rationality of the model.
