CONCLUSION
In this paper, we addressed the problem of maximizing the
power extracted from a system of series-connected PV modules outfitted with DPPs. To tackle some of the drawbacks of
previously-proposed centralized MPP algorithms, we introduced a distributed P&O algorithm that relies on neighbor-toneighbor communication, and requires only local voltage measurements. Hardware suitable for PV junction box integration
was developed. To verify the efficacy of the proposed algorithm,
we presented simulation and experimental results for a two-DPP
and a five-DPP system. We then demonstrated the scalability of
the algorithm by presenting simulation results for a 31-DPP
system.
