Abstract

In this paper, a decentralized voltage control service for the distribution system operator (DSO) is proposed and a comparison with a centralized strategy, such as the conservation voltage control (CVR) technique is presented. The service is designed to provide short term power reserve to the grid and it implements a local voltage-led demand response. The proposed service manages residential units' power demand by regulating the household devices' main voltages in a local way instead of changing the secondary voltage of the medium voltage/low voltage (MV/LV) transformer. The proposed service allows having a wider voltage regulation range, overcoming the CVR limits due to voltage violations at the end of the feeders. In order to analyze the decentralized control impact in terms of maximum control range available on the LV distribution grid, a simulation set based on OpenDSS and MATLAB is carried out. The results are compared with those obtained by using the CVR technique in order to highlight the advantages provided by the proposed solution.

住宅能源区集中与分散有功控制的比较研究

本文提出了一种分散的配电系统电压控制服务，并与集中的电压控制策略(如守恒电压控制技术)进行了比较。该服务旨在为电网提供短期电力储备，并实现本地电压主导的需求响应。拟议的服务以本地方式调节家用设备的主电压，而不是改变中压/低压(MV/LV)变压器的次级电压，来管理住宅单位的电力需求。拟议的服务允许具有更宽的电压调节范围，克服了由于馈线末端电压违规而造成的CVR限制。为了从最大控制范围角度分析分散控制对低压配电网的影响，基于OpenDSS和MATLAB进行了仿真。结果与使用CVR技术获得的结果进行了比较，以突出所提出的解决方案提供的优势。
