NYSERDA: Electric Vehicle Smart Charging
"As New York State continues to invest in electric vehicle infrastructure, it is also supporting innovative R&D efforts like this to make EV charging more efficient and cost-effective. The research taking place will help the state advance toward Governor Cuomo's goals for cleaner transportation, clean energy job growth and increased affordability of electric vehicles."John B. Rhodes , President and CEO, NYSERDA
The New York State Energy Research and Development Authority (NYSERDA), a public benefit corporation, offers objective information and analysis, innovative programs, technical expertise, and funding to help New Yorkers increase energy efficiency, save money, use renewable energy, and reduce reliance on fossil fuels. Smarter Grid Solutions was awarded funding via NYSERDA’s PON 2755 – Electric Vehicle-Enabling Technology Demonstration Program – for a project that supports new technologies and approaches to accelerate the market adoption of plug-in electric vehicles (PEVs) that makes PEV infrastructure easier to use and more economically viable in New York State.
The PEV market has grown rapidly in both New York State and the United States. Between May 2012 and September 2014, registered PEVs in New York grew from 1,000 to more than 10,000. Installations of electric vehicle supply equipment are also increasing rapidly, with more than 1,000 charging stations installed in the state. With the increase of these electric vehicles comes the challenge of integrating their charging into the grid in a low-cost manner, while also not straining aging electric infrastructure. Identifying the technical and commercial barriers to smart PEV charging requires consideration of advanced vehicle-grid integration via automation and control technologies, coordination with additional Distributed Energy Resources (DER) like solar photovoltaics, wind energy and battery storage, enhanced utilization of existing grid infrastructure, and real-time capacity assessment that interacts with pricing and incentives to charge vehicles in a cost-effective and sustainable manner.
The project identifies the most appropriate models for smart PEV charging and the technical and commercial barriers that exist, and provides recommendations for implementation that will be generically applicable in New York. International review of relevant smart charging projects, stakeholder engagement and vehicle-grid integration barrier analysis provided a basis for identifying the most appropriate model for smart PEV charging - ensuring an interaction with the electric grid that is economic, sustainable and mutually beneficial for all stakeholders, with alternative approaches available to mitigate distribution system impacts.
The smart PEV charging arena is not a new concept to Smarter Grid Solutions. The company is a key influencer in a number of critical trials for the Low Carbon London project in the UK, which is delivering smart PEV charging and demand side response in an urban environment. Using smart power management technology, the Low Carbon London project monitors power flows on the distribution system and controls power consumption from charging stations to limit the impact of power use on the electric grid. “It is widely recognized that electric vehicle charging will require a 'smart' element, and there are a number of projects within the US and internationally that are looking into ways of implementing this” said Bob Currie CTO and Co-Founder at Smarter Grid Solutions. “In order to accelerate deployment of smart PEV charging in New York State, a holistic approach to design needs to be taken that incorporates all stakeholders in PEV adoption.”
The delivered smart EV charging model assesses statewide implementation, recognizing that under continued EV load growth, grid constraints must be addressed by one or more of the following elements:
- Network Reinforcement Solutions: Building new transmission and distribution assets to support increased peak load.
- Increased Coordination with Distributed Generation: Deploying distributed generation alongside PEV adoption to connect local generation with local PEV charging.
- Increased Coordination with Energy Storage: The software application must not be site specific and shall be transferable to other locations.
- Active Network Management Solutions: Autonomous control to coordinate DER in response to real-time and forecasted grid conditions.
