Abstract-The penetration of plug-in electric vehicles and renewable distributed generation is expected to increase over the next few decades. Large scale unregulated deployment of either technology can have a detrimental impact on the electric grid. However, appropriate pairing of these technologies along with some storage could mitigate their individual negative impacts. This paper presents a framework and an optimization methodology for designing grid-connected systems that integrate plug-in electric vehicle chargers, distributed generation and storage. To demonstrate its usefulness, this methodology is applied to the design of optimal architectures for a residential charging case. It is shown that, given current costs, maximizing grid power usage minimizes system lifecycle cost. . Some PHEVs and EVs have been released into the market, and although estimates vary, by 2020 roughly 2 million PEVs are expected to be on the road in the US, increasing to 14 million (about 5% of the light duty vehicle fleet) by 2030 [3], [4]. However, penetration across the country is not expected to be uniform. Some west coast utilities expect PEV penetration of around 5% in their service territories by as early as 2020 [5]. Such levels of penetration will require large scale deployment of residential and public chargers [6], [7]. In parallel to these developments, there is strong legislative effort to mandate, or incentivize, large scale integration of renewable energy resources, including renewable distributed generation (DG), into the electric grid.

“…However, these methodologies do not address the design of grid-interfaced DG and/or storage systems, with their unique constraints and objective functions, to meet PEV charging requirements. An optimization methodology for the design of systems with a single grid-interfaced charger and a single renewable generator and a single storage unit was presented in [14]. This methodology is adequate for evaluating residential charger systems, as they typically only involve a single charger, but is inadequate for systems with multiple chargers, as is generally encountered in public charging systems.…”

Abstract-Increased penetration of plug-in electric vehicles (PEVs) will necessitate deployment of numerous PEV chargers. Pairing these chargers with renewable distributed generation (DG) and storage can potentially alleviate negative impacts on the distribution grid and help meet renewable portfolio goals. The optimal design of such integrated charging systems depends on many factors, including geographic location and charging profiles. This paper presents an optimization methodology for designing integrated PEV charging systems with multiple chargers and distributed resources. This methodology is used to investigate optimal designs for charging systems at a retail business and on a university campus. When PEV charging can introduce a demand charge, it is shown that the optimal design depends on the time of charging and the level of existing load. When non-negligible distribution system losses exist between charger locations, it is shown that the optimal size and location of DG and storage depends on the charging profile of the different chargers and the distribution efficiency.Index Terms-distributed power generation, electric vehicles, energy storage, linear programming, mixed integer linear programming.
