Volt/VAr/Demand control of consumer points in active distribution networks is a multidirectional function affected by the transmission, production, and network operations. Load tap changers and voltage regulators are the most common network elements for decreasing main fluctuations. However, the voltage changes performed by these network devices also affect the active and reactive consumptions at the subscriber side. The effect of solar power plants on the network is examined within the simulation study implemented on a realistic network model of Burdur TS, and an alternative method for voltage/reactive power control has been proposed. An experimental study is carried out in Burdur Kozluca feeder using the realistic output parameters of inverter devices of seven different Solar Energy Power Plants, and the new control algorithm is designed using these realistic data. This control process is materialized with a control unit used as a remote interface under the favor of a central decision structure worked upon a real-time Volt/VAr algorithm. Designed algorithm yields the power plants can receive inductive power from the distribution network with a demand of 10%, in which case the voltage was reduced from 1,146 p.u. to 1.001 p.u. Since existing solar power plants in the grid were used for Volt/VAr regulation, the requirement for an additional reactor, capacitor, OLTC installation on the feeder line was eliminated. Therefore, more functional control of the distribution network with the solar power plants may be obtained thanks to the designed control algorithm.

配电网Volt/VAr/需量控制的电站太阳能逆变器控制算法设计

主动配电网中用电点的伏特/无功/需求控制是受输电、生产和网络运行影响的多向功能。负载分接开关和电压调节器是最常见的用于减少主要波动的网络元件。然而,这些网络设备执行的电压变化也会影响用户侧的有功和无功消耗。在 Burdur TS 的现实网络模型上实施的模拟研究中检查了太阳能发电厂对网络的影响,并提出了一种电压/无功功率控制的替代方法。使用七个不同太阳能发电厂的逆变器设备的实际输出参数在 Burdur Kozluca 馈线中进行了一项实验研究,并利用这些现实数据设计了新的控制算法。该控制过程通过用作远程接口的控制单元实现,该控制单元在基于实时 Volt/VAr 算法的中央决策结构的支持下实现。设计的算法产生发电厂可以从配电网接收感应电力,需求为 10%,在这种情况下,电压从 1,146 pu 降低到 1.001 pu 由于电网中现有的太阳能发电厂用于 Volt/VAr 调节,不再需要在馈线上安装额外的电抗器、电容器和 OLTC。因此,由于设计的控制算法,可以对具有太阳能发电厂的配电网络进行更多功能控制。该控制过程通过用作远程接口的控制单元来实现,该控制单元在基于实时 Volt/VAr 算法的中央决策结构的支持下实现。设计的算法产生发电厂可以从配电网接收感应电力,需求为 10%,在这种情况下,电压从 1,146 pu 降低到 1.001 pu 由于电网中现有的太阳能发电厂用于 Volt/VAr 调节,不再需要在馈线上安装额外的电抗器、电容器和 OLTC。因此,由于设计的控制算法,可以对具有太阳能发电厂的配电网络进行更多功能控制。该控制过程通过用作远程接口的控制单元实现,该控制单元在基于实时 Volt/VAr 算法的中央决策结构的支持下实现。设计的算法产生发电厂可以从配电网接收感应电力,需求为 10%,在这种情况下,电压从 1,146 pu 降低到 1.001 pu 由于电网中现有的太阳能发电厂用于 Volt/VAr 调节,不再需要在馈线上安装额外的电抗器、电容器和 OLTC。因此,由于设计的控制算法,可以对具有太阳能发电厂的配电网络进行更多功能控制。设计的算法产生发电厂可以从配电网接收感应电力,需求为 10%,在这种情况下,电压从 1,146 pu 降低到 1.001 pu 由于电网中现有的太阳能发电厂用于 Volt/VAr 调节,不再需要在馈线上安装额外的电抗器、电容器和 OLTC。因此,由于设计的控制算法,可以对具有太阳能发电厂的配电网络进行更多功能控制。设计的算法产生发电厂可以从配电网接收感应电力,需求为 10%,在这种情况下,电压从 1,146 pu 降低到 1.001 pu 由于电网中现有的太阳能发电厂用于 Volt/VAr 调节,不再需要在馈线上安装额外的电抗器、电容器和 OLTC。因此,由于设计的控制算法,可以对具有太阳能发电厂的配电网络进行更多功能控制。
