Open Source Platform For Plug-in Electric Vehicle Smart Charging in California
A novel and flexible communication and control for PEVs in residential and small commercial settings.
This project was completed in 2019. This project developed and demonstrated electric vehicle charging and building load aggregation and management in response to 15-minute ahead grid condition signals. The research team demonstrated local load optimization to reduce site energy consumption while meeting driver mobility needs, building functionality, and building occupant comfort. Load management strategies such as the one demonstrated in this project can have the potential to save ratepayers $15M per year in 2024 in lowered utility costs (at 1 percent market penetration).[br /]
The research team has released the source code on GitHub for public consumption, which has been downloaded about 50 times. About 20 buildings are currently capable of integrating the developed charging communication and control platform. The research team cannot track the number deployments.
The project developed a one-way charging concept for PEVs that maximized intermittent renewable generation and minimized impacts to the distribution grid. The project focused on controlling the charging of plug-in electric vehicles (PEVs) in residential and small commercial settings using a novel and flexible open-source, open-software architecture charge communication and control platform. This software-based platform was embedded in the context of overall utility and residential and business electrical and building automation systems, lending itself to potential broad implementation by commercial interests due to its flexible architecture and "agnostic" approach to communications standards. Control strategies and applications were guided by an assessment of user needs and grid operation and ratepayer benefits, and the potential for one-way PEV charge control to lead to increased ability to accept intermittent renewable energy for California's electrical grid.
This project is estimated to result in $15 million per year reduction in electricity costs for ratepayers in 2024 from increased PEV charging energy efficiency and lower electricity generation costs.
This project could reduce carbon dioxide emissions by 72,500 metric tons per year in 2024 from increased PEV charging efficiency and increased fraction of intermittent operationally GHG-free renewable electricity generation.
This project is expected to increase reliability of the electric distribution grid and reduce frequency of outages in residential areas. Coordinated charging of PEVs in distribution networks could reduce impacts from sudden surg
