Power Management of Multi-paralleled Bidirectional Interlinking Converters in Hybrid AC/DC Microgrids: A Dynamic Consensus Approach
Hybrid AC/DC microgrids (MG) offer a promising way to incorporate heterogeneous energy sources into AC or DC subgrids while minimizing energy conversions stages. For a MG working in long term, the capacities of both AC and DC subgrids would inevitably increase, which may result in more power interactions between the two subgrids. In this context, a single bidirectional interlinking converter (BIC) which bridges AC and DC subgrids may suffer from overstress. Hence, multi-paralleled BICs configuration should be adopted and well managed. This paper proposes a dynamic consensus approach for proportional power allocation among multiple BICs, thereby avoiding the overcurrent of a particular BIC and enhancing the flexibility of system communication. The effectiveness of the proposed power management strategy has been verified by simulation results.
