N2 - The integration of distributed generation (DG) systems on customer side brings a revolutionary impact and challenge to the operation, control and protection of distribution system. The transient simulation and real-time simulation of DG system become more and more important. FPGA is needed in real-time simulation for high computational capability. For this reason, this paper proposes an asynchronous communication method between electrical and control system. The time-step is shortened. The interpolation method of source element based on FPGA is realized. The setting criteria of time-step is loosened without sacrificing much resource. To validate these proposed methods, a photovoltaic-battery hybrid generation system is simulated in real-time. The time-step of electrical and control system is 1.096 μs and 1.696 μs. The waveforms show great coherence with the offline simulation in PSCAD/EMTDC.
