Implementing EV-Based Grid Services for Microgrids and VPPs

The projected growth in plug-in EVs (PEVs) offers challenges and opportunities to distribution utilities. If not managed in an intelligent way, these PEVs can pose a threat to overall grid reliability. Yet, if aggregated and optimized with smart controls, they can offer grid services under new business model platforms such as microgrids and virtual power plants (VPPs). While the primary purposes of these platforms differ—resiliency versus bidirectional value exchanges—they share the goal of extracting value from distributed energy resources (DER) portfolios.

Vehicle grid integration (VGI) enables PEVs to participate in grid balancing schemes as generation or demand assets for grid operators as well as similar balancing options for smaller subsets of the grid, including microgrids and VPPs. PEVs may do this by modulating the rate of power at which the battery is charged, known as V1G (unidirectional VGI), or by providing power back to the grid, known as vehicle-to-grid (V2G).

This Guidehouse Insights report discusses how to develop a strategy to best extract grid services embedded in PEV batteries, charging loads, and charging infrastructure to help support microgrid and VPP deployments. The study defines the grid services possible from PEVs, showcases global deployments that tap PEVs as DER for microgrids and VPPs, and identifies lessons learned from deployments that point to market opportunities. Actionable recommendations for PEV, microgrid, and VPP stakeholders when implementing PEV-based applications within the next 5 years are also provided.
