SCOPE This document applies to a Plug-in Electric Vehicle (PEV) which is equipped with an onboard inverter and communicates using the Smart Energy Profile 2.0 Applicat
18、ion Protocol (SEP2). It is a supplement to the SEP2 Standard, which supports the use cases defined by J2836/3TM. It provides guidance for the use of the SEP2 Distributed Energy Resource Function Set with a PEV. It also provides guidance for the use of the SEP2 Flow Reservation Function Set, when use
19、d for discharging. It is not intended to be a comprehensive guide to the use of SEP2 in a PEV. 1.1 Purpose SAE Information Report J2836/3TMdefines two system architectures in which a Plug-in Electric Vehicle (PEV) and the connected Electric Vehicle Supply Equipment (EVSE) together serve as a Distrib
20、uted Energy Resource (DER). The inverter could be located in the PEV in which case AC power would flow from the PEV through the EVSE to the electric power system. Alternatively, the inverter could be located in the EVSE in which case DC power would flow between the PEV battery and the EVSE as needed
21、 by the inverter to perform the selected DER function. The entity that contains the inverter should be the focus of any communication with the system that is controlling the DER devices for the DER application. This communication should be with the PEV in the case of an onboard inverter or with the
22、EVSE in the case of an external inverter. While this recommended practice only applies to a PEV with an onboard inverter, it could optionally be followed by an EVSE manufacturer to guide SEP2 implementation for the case where the inverter is located in the EVSE. J2836/3TMprovides guidance for update
23、s required to J2847/2 to provide a DER DC mode that will allow the inverter in an EVSE to use the PEV battery when operating together as a DER. This DER DC mode will be an inner loop control mode modeled on the internal PEV communication between the inverter and the battery management system for an
24、onboard inverter. This document has five specific objectives: Provide guidance for WHAT information needs be exchanged with the PEV using SEP2. Provide guidance for HOW to manage the actual exchange of information with the PEV using SEP2. Define RULES of engagement for the creation and use of inform
25、ation, the timing of information exchanges, and the resolution of conflicts by the PEV. The behavior of the PEV is governed by its own controls, displays, and embedded software. The purpose of SEP2 is only to move information to and from the PEV in support of the PEV functions. While SEP2 provides s
26、ome recommended behavioral guidance, this document should be followed for the implementation of PEV functionality if there is a conflict. Identify CHANGES for the next version of SEP2 and IEC 61850 to better support the requirements of SAE J2836/3TM. In some cases SEP2 supports SAE J2836/3TMrequirem
27、ents, but IEC 61850 does not. In other cases, the reverse is true. Provide EXAMPLES of the use of SEP2 to perform selected V2G applications. There are too many possible V2G applications to create an exhaustive set of examples. However, a few examples can help guide the development of the embedded PE
28、V software required to implement the protocol for the inverter functions. SAE INTERNATIONAL J2847/3 Issued DEC2013 Page 4 of 93 2.

DEFINITIONS 3.1 ADVANCED METERING INFRASTRUCTURE (AMI) AMI or Advanced Metering Infrastructure typically refers to the full measurement and collection system that includes meters at the customer site, commun
41、ication networks between the customer and a service provider, such as an electric, gas, or water utility, and data reception and management systems that make the information available to the service provider. 3.2 AGGREGATOR An individual PEV may not produce or consume enough power to be able to part
42、icipate by itself in an application such as frequency regulation. An aggregator is an entity (which may not be a utility) that coordinates the power flow for a group of PEVs to allow them to meet the minimum power capacity required to participate in an application. The aggregator functions to, among
43、 other things: a) schedule aggregated V2G services with a grid operator, utility, and other entities; b) dispatch individual vehicles according to various factors including available V2G services and driver requirements c) aggregate response telemetry and relay to utility or grid operator; d) mainta
44、in a registry of vehicle identities and characteristics. 3.3 CLIENT In the standard client-server model, a client is the device or host that interacts with a server to obtain information related to a resource hosted by the server. 3.4 CONTROL SIGNAL The UCAIug HAN SRS defines this as a structured me
45、ssage sent from an authorized party requesting operational state change of a device. Devices are expected to respond within the operation of their control systems and algorithms. This includes messages to DER devices for the purpose of controlling both active and reactive power. 3.5 COORDINATED UNIV
46、ERSAL TIME (UTC) Coordinated Universal Time (UTC), once known as Greenwich Mean Time (GMT), is the reference time at the Greenwich meridian (London, U.K.). Time in the Smart Energy Profile 2.0 (SEP2) is defined as a signed 64 bit integer value representing the number of seconds from midnight January
47、 1, 1970, in UTC, not counting leap second corrections to UTC (35 seconds through 2012). 3.6 DEMAND RESPONSE A temporary change in electricity consumption by a demand resource (e.g., smart appliance, pool pump, PEV, etc.) in response to a Control Signal which is issued. 3.7 DISTRIBUTED ENERGY RESOUR
48、CE (DER) Distributed Energy Resources are small, modular Distributed Generation (DG) and storage technologies that provide electric capacity or energy where it is needed on the distribution grid. DG, which includes gensets, solar panels, and small wind turbines, only serve as a source of energy. Storage is a unique form of DER because, unlike pure DG
