Security of Supply in Active Distribution Networks with PHEV-Based Strategic Microgrids

With the increased integration of intermittent distributed generation (DG) into active distribution networks the security of power supply to consumers is challenging. Plug-in hybrid electric vehicles (PHEVs) can be used as standing reserve units that can mitigate intermittency of power. They can also provide strategic supports in the form of microgrids. Taking into account merits of PHEVs, the chapter proposes a methodology to mobilize the strategic microgrids for the improved security of supply in an active distribution network. It also quantifies the feasible improvement in security of supply with PHEV-based strategic microgrids. The Monte Carlo simulation is the core engine of the approach and it captures many uncertainties that can be embedded in an active distribution network. A case study is performed and the results suggest that PHEV-based strategic microgrids can improve the security of power supply to consumers. The PHEV-based strategic microgrids would not always be the same strategic microgrids with increased penetration of intermittent DG. Strategic ability of PHEV-based microgrids dynamically change with increased penetration of DG.
