Distributed Control of Hybrid AC/DC Microgrids: from Synchronous to Asynchronous Algorithms.

摘要: Hybrid AC/DC microgrids (MGs) have become a promising manner for better interconnection of various kinds distributed generators that are inherently AC or DC electric sources. This paper addresses the asynchronous power control problem hybrid microgrids, considering imperfect communication due to non-identical sampling rates and delays, etc.. To this end, we first formulate optimal MGs devise synchronous algorithm. Then, analyze impact asynchrony on propose an iteration algorithm based version. By introducing random clock at each iteration, different types fitted into unified framework, where is converted fixed-point problem, leading convergence proof. We further provide upper bound estimation time delay in communication. Finally, benchmark MG utilized verify effectiveness advantages proposed
