Grid Communication Interface for Smart Electric Vehicle Services Research and Development
Advancing current and future grid services for PEV through V2G communications and OpenADR 2.0
This project was completed in 2019. The project team designed and prototyped two models of Level 2 chargers capable of demand response according to the V1G (managed charging) use cases defined by SCE and PG&E. The project team conducted fast charge and discharge simulation of the PEVs using OpenADR signals and collected performance data. The EVSEs (Level 2 and Level 3) were integrated in a microgrid with 110 kW solar panels to demonstrate the feasibility of the InCISIVE system in mitigating renewable energy overgeneration. Using low-priced renewable energy stored in PEVs instead of energy from natural gas peakers results in energy savings of 21.9 MWh and about a $3,700 savings per PEV per year for California ratepayers.View Final Report
Andromeda Power developed an advanced smart grid communication interface that allows utilities to send dispatch signals to PEVs in real-time to optimize the bidirectional power flow of PEV battery packs depending on local power conditions such as congestion, power quality, voltage and frequency, while maintaining the driver's mobility needs. The grid communication interface operates with a virtual machine that is able to interface with PEVs of any standard. The real-time monitoring and control of the stations provided the California electric investor-owned utilities with a means of quick, automated demand response.
The annual energy shift capacity introduced by InCISIVE is about 11 MWh/year (= 30 kWh x 365) toward the end of On-Peak period and in the following Mid-Peak period when marginal electricity is produced by natural gas peaker plant
Each PEV (30 kWh storage) optimally used for energy storage that charges and discharges once per day is estimated to result in approximately 7 metric tons per year of GHG reductions through the offsetting of natural gas peaker pl
