GridPoint, Inc., a provider of smart grid software, will provide its latest generation of electric vehicle management software (earlier post), Smart Charging 3.0, to support the eTEC/Nissan LEAF deployment of electric vehicles and charging infrastructure—the largest yet in the US. (Earlier post.) The company made the announcement at the Plug-In 2009 Conference and Exposition in Long Beach, CA.
GridPoint will provide smart charging and data logging capabilities to utilities in strategic markets of the eTec program in Arizona, California, Oregon, Tennessee and Washington that will support the deployment of up to 5,000 Nissan LEAF vehicles and a network of up to 12,750 charging stations.
GridPoint’s charging management software will give utilities the ability to deploy load shifting, load shaping, renewables integration and demand response strategies. Advanced smart charging capabilities, such as synchronization with the availability of renewable energy, may also be explored.
To date, utility-led smart charging trials have been limited by the availability of grid-connected vehicles. The size and scope of this project creates a unique and valuable opportunity to assess and qualify:
- Effects of a mature plug-in electric vehicle environment, with and without smart charging, on multiple electrical grids;
- Benefits of smart charging on grid reliability to inform utility, PUC and regulator decision making on vehicle-related rate schedules;
- Customer satisfaction and perception of various smart charging scenarios; and
- Incentive programs to ensure maximum participation in smart charging programs.
Smart Charging 3.0. For two years, GridPoint has been building and deploying smart charging software, collecting data from hundreds of converted plug-in vehicles and gathering feedback from utility customers. Smart Charging 3.0 builds on this to deliver:
Forecasting and Backcasting: GridPoint has introduced forecasting capabilities for plug-in vehicle load, setting a new standard for smart charging. Based on historic behavior, Smart Charging 3.0 predicts vehicle-related load up to 24 hours in advance. This new functionality allows utilities to better plan for the impact electric transportation load will have on the grid and to proactively initiate smart charging strategies to mitigate and/or leverage that load. Additionally, Smart Charging 3.0 provides a visual display of plug-in charging impacts with and without charging management for the previous 24 hours - allowing utilities to quickly assess the effectiveness of their smart charging strategies.
Demand Response Functionality: Smart Charging 3.0 supports external demand response notification via the OpenADR standard, allowing plug-in vehicles and charging stations to stop charging during critical peak events. System users are notified of ongoing demand response events through real-time messaging that appears on GridPoint’s smart charging and data logging portals. Consumer notification via Web portal or handheld device is also enabled.
Enhanced Smart Charging Portal Design: Through the addition of intuitive functionality in the Smart Charging Portal, GridPoint has improved the ability to quickly ascertain the impact of vehicle charging load and the success of various smart charging strategies, while also providing a greater ability to drill down and explore charging behavior during a specific time of day. Enhanced functionality includes 24-hour display of historic and predicted load/generation, zoomable charts, mouse-over data detail, and real-time display of aggregated statistics of all vehicles deployed in smart charging programs.
Smart Charging 3.0 also enhances system scalability and reliability via performance optimization and increased redundancy. In response to requests from utilities and research institutions, GridPoint has expanded the software’s data capture to include average power factor, battery pack voltage and other advanced performance information.
