What is it about?
A new optimal control model of a microgrid with smart PEVs and space heating. Battery degradation and thermal dynamics of PEVs and buildings included. A case study on 1–10 houses with empirical data from Southern Sweden. 8–33% cost savings with optimal control compared to energy-efficient baseline. Battery degradation cost significantly decreases the added value of vehicle-to-grid.

Why is it important?
A case study is conducted on 1–10 net zero energy houses with detailed empirical data, resulting in 8–33% yearly electricity cost savings per household with various electric vehicle and space heating system combinations. The self-consumption of PV is also significantly increased.
Perspectives
Optimal control of micro-grids with PV, battery, and EV is very important to generate economic benefits. Neglecting battery degradation completely leads to overestimation of the vehicle-to-grid cost benefit.
