IEC 61968-5:20 20描述了DERMS功能的企业集成所需的一组功能。这些交换很可能发生在DERMS和DMS之间。然而，由于这是可以利用IEC 61968-100:2013进行应用集成(使用web服务或JMS)或其他松耦合实现的企业集成标准，因此对于DERMS可以与其交换信息的系统没有技术限制。此外，应当注意，DERMS可以使用各种标准和协议与单个DER通信，例如IEC 61850、IEEE 2030.5、分配网络协议(DNP)、Sunspec Modbus或可能的开放现场消息总线(OpenFMB)。DERMS的一个作用是代表系统运营商管理这种通信的差异和复杂性。然而，与单个DER的通信超出了本标准的范围。读者应参考这些标准来了解与单个DER智能逆变器的通信。 范围将限于以下用例类别: ？DER组创建——总体管理DER的机制 ？DER组维护-添加、删除或修改给定DER组的成员和/或聚合能力的机制 ？DER组删除-移除整个组 ？DER组状态监测-用于量化或确定DER组的当前能力和/或状态的机制 ？DER组预测-用于预测未来给定时间段内DER组的能力和/或状态的机制 ？DER组调度-用于请求将DER组的指定能力调度到电网的机制 ？DER组电压斜坡速率控制-用于请求DER组遵循斜坡速率曲线的机制 ？DER组连接/断开——一种请求DER隔离自身或根据需要重新连接到电网的机制。

IEC 61968-5:2020 is the description of a set of functions that are needed for enterprise integration of DERMS functions. These exchanges are most likely between a DERMS and a DMS. However, since this is an enterprise integration standard which may leverage IEC 61968-100:2013 for application integration (using web services or JMS) or other loosely-coupled implementations, there are no technical limitations for systems with which a DERMS might exchange information. Also, it should be noted that a DERMS might communicate with individual DER using a variety of standards and protocols such as IEC 61850, IEEE 2030.5, Distribution Network Protocol (DNP), Sunspec Modbus, or perhaps Open Field Message Bus (OpenFMB). One role of the DERMS is to manage this disparity and complexity of communications on the behalf of the system operator. However, the communication to individual DER is out of scope of this standard. Readers should look to those standards to understand communication to individual DER’s smart inverter.
The scope will be limited to the following use case categories:
？ DER group creation – a mechanism to manage DER in aggregate
？ DER group maintenance – a mechanism to add, remove, or modify the members and/or aggregated capabilities of a given group of DER
？ DER group deletion – removing an entire group
？ DER group status monitoring – a mechanism for quantifying or ascertaining the current capabilities and/or status of a group of DER
？ DER group forecast – a mechanism for predicting the capabilities and/or status of a group of DER for a given time period in the future
？ DER group dispatch – a mechanism for requesting that specified capabilities of a group of DER be dispatched to the grid
？ DER group voltage ramp rate control – a mechanism for requesting that a DER group following a ramp rate curve
？ DER group connect/disconnect – a mechanism to request that DER either isolate themselves, or reconnect to the grid as needed.
