摘要: 交直流混合微网可综合发挥交流与直流的互补优势,其优化运行是微网领域的重要研究课题。该文综合考虑经济成本和环境成本,建立了交直流混合微网优化运行模型。基于交直流混合微网的结构特性,通过拆分协作思想将复杂的优化问题拆分为2个相对独立的交流区域优化问题和直流区域优化问题;通过引入混沌机制,加入星体被吸引的惯性和速度约束,优化初始星体的生成方式等,提出了基于改进黑洞算法的交直流混合微网优化方法,对交、直流子区域优化问题进行求解。仿真算例表明,提出的基于拆分协作思想的改进黑洞算法可以有效解决变量较多、结构较复杂的交直流混合微网的优化运行求解问题,能够以较少的综合运行成本实现更优的运行效果,验证了所提算法的有效性。

Abstract: AC/DC hybrid microgrid can take complementary advantage of both AC and DC, and its optimal operation is an important research topic in area of microgrid. This paper establishes a mathematical model for the optimal operation of AC/DC hybrid microgrid with comprehensively considering economic cost and environmental cost. Based on the coevolution theory and the structural characteristics of AC/DC hybrid microgrid, a complicated optimization problem is split into two relatively independent simple problems: AC area optimization problem and DC area optimization problem. And an improved black hole algorithm is proposed to settle this optimal problem by the introduction of chaos mechanism, the inertial and velocity constraints of stars as well as improvement on the generation of initial stars. The simulation results show that the proposed coevolution improved black hole algorithm is suitable for the optimal operation problem of AC/DC hybrid microgrid with myriad and complex variables, and the better operation strategy can be reached at comprehensive operating cost as low as possible in this model, which verifies the effectiveness of the proposed algorithm.

Key words: AC/DC hybrid microgrid, optimal operation, improved black hole algorithm
