摘要: 交直流混合微网可综合发挥交流微网与直流微网的特点,碳交易机制符合低碳经济理念。根据交直流混合微网的特点,建立了计及碳排放成本的交直流混合微网优化运行模型,通过对比不同权重下的经济指标和碳排放指标,研究碳交易机制的引入对混合微网优化运行的影响。在此基础上,引入双向换流器损耗模型,研究双向换流器损耗对混合微网经济调度的影响。算例结果表明,等权重调度策略具有更优的经济性和环保性,双向换流器损耗模型的引入改变了交流区域和直流区域可控微源出力,更加贴合实际。

关键词: 交直流混合微网, 碳交易, 双向换流器损耗, 优化运行

Abstract:

AC-DC hybrid microgrid can give full play to the complementary advantages of AC microgrid and DC microgrid, whose carbon trading mechanism conforms the concept of low-carbon economy. According to the characteristics of AC-DC hybrid microgrid, this paper constructs the optimization model of AC-DC hybrid microgrid with considering the cost of carbon emission. By comparing the different weights of the economic indicator and carbon emission indicator, this paper studies the influence of carbon trading mechanism on the optimal operation of hybrid microgrid. On this basis, this paper introduces a loss model of the bidirectional converter and studies
the influence of the bidirectional converter loss on the economic dispatch of hybrid microgrid. The simulation result shows that the equal weight dispatch
strategy has better economic and environmental protection, and the application of the bidirectional converters loss model changes the controllable micro source
output in AC area and DC area, which is more applicable for the real needs.

 

Key words: AC-DC hybrid microgrid, carbon trading, bidirectional converter loss, optimal operation
