The paper presents an approach for online centralized control in active distribution networks. It combines a proportional integral (PI) control unit with a corrective control unit (CCU), based on the principle of Model Predictive Control (MPC). The proposed controller is designed to accommodate the increasing penetration of distributed generation in active distribution networks. It helps in continuously satisfying the reactive power requirements of the transmission system operators (TSOs), while maintaining an acceptable voltage profile in the active distribution network, and simultaneously minimizing the total active power losses. The controller also ensures compliance to operation requirements of distribution network operators (DNOs). By replacing the full load flow (LF) calculation with sensitivities, derived from a linearized model of the network, the controller can work in real-time applications. Moreover, the computational burden of the proposed controller is reduced since the CCU is activated only when a voltage violation or considerable change of operation condition occurs. The performance of the proposed controller is demonstrated on a 11-kV test network with 75 buses and 22 distributed generators.

基于MPC的有源配电网络集中电压和无功控制。

本文提出了一种主动配电网络在线集中控制的方法。它基于模型预测控制（MPC）的原理，将比例积分（PI）控制单元与校正控制单元（CCU）结合在一起。拟议中的控制器旨在适应主动式配电网络中分布式发电的日益普及。它有助于持续满足传输系统运营商（TSO）的无功功率要求，同时在有源配电网中保持可接受的电压曲线，同时最大程度地减少总有功功率损耗。该控制器还确保符合配电网络运营商（DNO）的运行要求。通过用灵敏度代替满载流量（LF）计算，从网络的线性化模型派生出来的控制器可以在实时应用中工作。此外，由于仅当发生电压违规或操作条件发生重大变化时才激活CCU，从而减轻了所提出控制器的计算负担。所提出的控制器的性能在具有75条母线和22台分布式发电机的11 kV测试网络上得到了证明。
