Comparison of parallel implementations of controls on GPU for transient simulation of power system

Widely utilization of converter-based interfaces in AC-DC hybrid power system requires precise modeling and simulation for complicated and large-scale control system. However, this process can be accelerated by fine-grained parallel algorithm, and therefore improving the simulation efficiency. In this paper, two kind of fine-grained parallel control system solving methods are proposed and implemented on Graphics Processing Units (GPU) platform to accelerate a large-scale control system simulation. According to the test results, the simulation efficiency of the two methods can be effectively improved by using GPU.
