摘要
在微电网优化设计的研究中,为了研究微电网中含微型燃气轮机的经济性,在满足热电负荷需求和电网安全约束的前提下,提出了基于综合效益最大化额微电网经济优化模型。综合考虑设备折旧成本、运行与维护成本、燃料成本、购电成本和环保折算成本,分别在并网和孤网运行模式中建立优化模型。并采用粒子群算法进行求解,对比分析微电网有、无燃气轮机的综合成本和各分布式电源的输出功率。结果显示:所建模型保证了微电网的可持续供电,含微型燃气轮机的电源配置方案能够取得较大的社会经济效益,确保综合效益最大化,为微电网的设计提供理论基础。
In order to research the economy of the micro - grid with micro - turbine, the economic optimization model based on maximizing comprehensive benefits was set up on the premise of satisfying the constraintson system operation and demands of loads. At island model and grid - connected model, optimization models were developed in the micro - grid taking into account equipment depreciation cost, operation and maintenance costs, cost of fuel, pow- er purchase cost and reduced environmental cost. The swarm optimization algorithm was used to solve this model, comparing and analyzing the comprehensive cost in the running mode with and without micro - turbine and the output of distributed generation. The results show that the model can ensure the reliability of electricity and the power con- figuration scheme with micro - turbine can ensure best economy. That provides a theoretical basis for the planning of micro - grid.
