A Weighted Criterion Based Inter-phase Power Management for Balancing Single-phase Residential Microgrids with Experimental Verification

A weighted criterion based secondary control layer strategy for balancing single-phase residential microgrids is presented in this paper. This strategy is built on top of previously developed intra- and inter-phase power management strategies. The proposed control scheme involves logic based decision making along with single-phase back-to-back converters that interconnect each of the three phases at the distribution side of the grid. This strategy is effective where each phase has its own generation via renewable energy resources with storage units. Two cases are simulated with high fidelity simulations performed in PSCAD/EMTDC. Experimental verification is also carried to validate the simulation results.
