Abstract
Electricity-hydrogen coupled DC microgrid is of great significance for energy structure adjustment and efficient consumption of renewable energy. However, at present, such systems lack high-precision simulation support, and the transient simulation technology for large-scale microgrid systems is not perfect. In order to solve these problems, this paper form an electricity-hydrogen coupled DC microgrid simulation platform, and studies the function realization and the efficiency improvement of transient simulation. Firstly, the Euler algorithm is adopted to realize the transient simulation of the microgrid system for the functional requirements of the electricity-hydrogen coupled DC microgrid. Secondly, for different system sizes and computing platforms, an adaptive parallel computing optimal mode selection algorithm is proposed to improve the simulation efficiency. The experimental results show that the algorithm improves the computing efficiency of the large-scale electricity-hydrogen coupled DC microgrid system by about 40%.
