Ultimately, smart charging can delay or in some cases even remove the need for investment in network reinforcement. In turn, these reduced investments lead to reduced network use of system charges and eventually, energy bill savings for end-customers.
Benefits from smart EVs could be further enhanced through V2G technology, as demonstrated by Kaluza in its world-leading domestic V2G trial. V2G technology could reduce domestic load at peak times through a V2G exporting and powering the home.
Although, here, not considered in the context of electric heat, smart charging is a highly versatile technology. If and when smart charging secondary peaks pose a challenge, the necessary changes to optimisation constraints could be activated through the market signals which smart charging can optimise against. For example, through network charges, flexibility markets, or market prices with locational components reflective of local network needs.
Networks should not be afraid, nor shy away from smart charging and its secondary peaks. Instead, networks should embrace this novel technology. Smart charging will offer an unprecedented level of control over demand embedded in the low voltage networks. This will create opportunities to shift load from the domestic peaks of today, and the new peaks of tomorrow. So what? This will open the door, enabling DNOs to build a smart, flexible and dynamic energy system of the future.
