5、Use Cases for Plug-in Vehicle Communication as a Distributed Energy Resource RATIONALE This document will use both SAE J2836/1 (charging the PEV using existing and optimized Utility programs) and SAE J2836/2 (DC charging) as a basis and then add the additional information for the Plug-In Electric Ve
6、hicles (PEV) to function as a Distributed Energy Resource (DER). It is expected that including DER functions to a PEV provides a more complete solution to Smart Charging that includes Reverse Power Flow and other opportunities to stabilize the local grid distribution network and its transformers. Th
7、is is the first version of this document and completes step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 is to record as much information on “what we think works” and publish. The effort will continue to step 2 that allows public review for additional com
8、ments and viewpoints, while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version. TABLE OF CONTENTS 1. SCOPE 4 1.1 Purpose . 4 2. REFERENCES 6 2.1 Applicable Docum

SCOPE This SAE Information Report est
25、ablishes use cases for a Plug-in Electric Vehicle (PEV) communicating with an Energy Management System (EMS) as a Distributed Energy Resource (DER). The primary purpose of SAE J2836/3 is to define use cases which must be supported by SAE J2847/3. This document also provides guidance for updates to S
26、AE J2847/2 to allow an inverter in an EVSE to use the PEV battery when operating together as a distributed energy resource (DER). 1.1 Purpose The title of this document suggests that its primary purpose is to present use cases for communication with a PEV as a DER. This is true, but this document wi
27、ll also provide a broader view of the issues associated with reverse power flow and how a PEV as a DER can serve the bulk grid, the distribution system, and a customer premises. Distributed Energy Resources are small, modular Distributed Generation (DG) or energy storage systems that provide electri
28、c capacity or energy where it is needed on the distribution grid. A PEV using a “utility-interactive inverter” can be hooked up in parallel with the primary grid power and it is considered to be a Distributed Energy Resource (DER). The use of a PEV as a DER will be called Vehicle to Grid (V2G). The
29、term is often associated with the concept of an aggregator coordinating the power flow of many PEVs to provide frequency regulation for the bulk grid. However, V2G is not just about the bulk grid. The V2G and DER functionality can also be used by a facility energy management system to offset other f
30、acility loads during periods of peak demand. These are only two of many possible V2G applications. Even if a PEV is not capable of reverse power flow, it can still be used as a DER device to allow for active control of charging for grid purposes. The use of a variable load for grid purposes is somet
31、imes called Demand Dispatch or Demand Management. This can be considered to be a single-sided use of a DER device and is no different than a generator that can only vary power output. A PEV could also serve as a power source for tools or other devices, where grid power is not available, or provide e
32、mergency backup power for a home following a loss of grid power. These are all off-grid applications. This is all about pure reverse power flow and it can be engaged manually using controls and displays provided by the vehicle manufacturer. For these applications the vehicle is just like a portable
33、standby generator. In all of the discussion of the benefits of reverse power flow and the use of a PEV as a DER, it is important to always remember that the primary purpose of the energy stored in the vehicle battery is transportation. While it may acceptable for a stationary grid storage unit to di
34、scharge all afternoon and recharge at night, a PEV participating in a V2G application may need to be fully charged by the end of the workday. The use cases for a PEV serving as a DER will need to account for two objectives: serving the grid in a V2G application and also having enough energy by the t
35、ime of departure to meet its transportation needs. Figure 1 provides an overview of the purpose of the document. A stationary, grid-connected, energy storage system (ESS) is shown at the top of the diagram. It is considered to be a distributed energy resource (DER). There is a great deal of work goi
36、ng on to integrate ESS units into the grid. A plug-in electric vehicle (PEV) with an on-board inverter looks like the stationary ESS and can be considered to be a DER device. This system is shown in the middle of the diagram. The possible use of reverse-flow capable PEVs, as inverter-based ESS units
37、, has generated significant interest. This potential use of PEVs has become known as vehicle to grid (V2G). Alternatively, the inverter could be located externally in the electric vehicle supply equipment (EVSE) in which case the PEV battery is only used to supply or absorb DC power as required by t
38、he inverter. This system concept is shown at the bottom of the figure. It is often assumed that the premises network will use the Smart Energy Profile 2.0 (SEP2) for communication and the PEV will be able to use this protocol for communication directly through the EVSE to the Energy Services Interfa
39、ce (ESI). The ESI can be thought of as the gateway between the premises network and the outside systems. This SEP2 assumption may not be true for many premises networks, in which case the EVSE will need to translate messages from the protocol used by the local network into SEP2 used by the PEV. SAE
40、J2847/3 will define the communications between the EVSE and the PEV for those cases where the inverter is on-board the PEV. It is expected that the EVSE to PEV communications would be by power line carrier (PLC) on the control pilot. If the premises network uses SEP2 and the EVSE is not needed to pe
41、rform protocol translation for the PEV, it may be possible for the PEV to use a wireless link directly to the network.

42、5 of 130 FIGURE 1 - PURPOSE OF DOCUMENT When the inverter is located in the EVSE it will need to directly interact using the network protocol. This could be SEP2 but in many sites it could be a different protocol. The use cases in this document and J2847/3 could help with the design of the EVSE comm
43、unications, but there are other documents such as IEC TR 61850-90-7 that could be directly used by the EVSE manufacturer. An external inverter will need to interact with the battery management system (BMS) of the PEV. This will be similar to the communications used for fast charging as defined by J2
44、847/2, but the focus will be very different and changes will be required for DER use. For fast charging, the PEV BMS manages the charging current using the data link. For DER use, the inverter will draw from the battery or push into the battery whatever current is needed to perform its DER function.
45、 In this case the BMS defines limits for the inverter, but does not manage the inverter power conversion.
