• Management of EV load in synch with demand reduction and solar/wind generation ramps
• Energy storage to mitigate Fast Charge grid impacts and emergency power in the home
• Low power bi-‐directional energy management of PEVs – integration with commercial building DC bus
• Vehicle to building peak load reduction
• Vehicles as a flexible MicroGrid component
• Charging vehicles from Solar directly

Solar Microgrid Functions

Powering the 21st Century Economy
A Very Different Future?
• As the number of loads and generators connected to the grid increases; – the controllability and control model of the grid will change – reliability will only be maintained through distributed intelligence and
control
• Complexities at the edge – DR programs, DG programs, MicroGrids, grid divorce, AMI / HAN
• This strongly suggests a more highly distributed energy system will play a major role in the modern grid.

Hybrid Integrated Systems (Microgrid) Trends
• MicroGrids will con1nue to be an important niche for high-‐reliability and emerging markets (premium product or grid parity driven)
• Integrated systems with capabili1es to locally reduce the renewable genera1on variability (VRG) in output will increase the viability of renewables
• Predic1on that hybrid systems (Renewables and natural gas, Renewables and storage, Grid-‐Friendly Renewables) will become the next mass market product (Grid Variability + Economics + Risk Reduc1on + Co-‐loca1on with home solar and Electric Vehicles == Solar Microgrids
