只提供摘要形式。在本文中，我们考虑了一个主动配电网络（ADN），它通过广播低速率通信信号使用实时需求响应来执行初级电压控制。ADN还拥有分布式电能存储。我们表明，可以使用用于控制负载的相同广播信号来管理分布式存储。为此，我们提出了一个适当的控制律嵌入到分布式电力存储控制器中，该控制器对定义的广播信号作出反应，以控制有功和无功功率注入。我们特别分析了电力存储系统由超级电容器阵列组成的情况，以及ADN使用电网显式拥塞通知（GECN）进行实时需求响应的情况，这是作者在之前的贡献中开发的。我们根据网络的特性估计成功执行电压控制所需的能量储备。在IEEE 34节点测试馈线上对该方案的性能进行了数值评价。根据线路特性，我们进一步评估无功与有功控制注入的影响。我们发现，在不改变需求响应信号的情况下，在存储设备中实现适当设计的控制器使它们能够成功地实现初级电压控制。
Summary form only given. In this paper we consider an active distribution network (ADN) that performs primary voltage control using real-time demand response via a broadcast low-rate communication signal. The ADN also owns distributed electrical energy storage. We show that it is possible to use the same broadcast signal deployed for controlling loads to manage the distributed storage. To this end, we propose an appropriate control law to be embedded into the distributed electrical storage controllers that reacts to the defined broadcast signal in order to control both active and reactive power injections. We analyze, in particular, the case where electrical storage systems consist of supercapacitor arrays and where the ADN uses the Grid Explicit Congestion Notification (GECN) for real-time demand response that the authors have developed in a previous contribution. We estimate the energy reserve required for successfully performing voltage control depending on the characteristics of the network. The performance of the scheme is numerically evaluated on the IEEE 34-nodes test feeder. We further evaluate the effect, depending on the line characteristics, of reactive versus active power controlled injections. We find that without altering the demand-response signal, a suitably designed controller implemented in the storage devices enables them to successfully contribute to primary voltage control.
