This paper presents experimental validation of a distributed optimization-based voltage control system. The dual-decomposition method is used in this paper to solve the voltage optimization problem in a fully distributed way. Device-to-device communication is implemented to enable peer-to-peer data exchange between agents of the proposed voltage control system. The paper presents the design, development and hardware setup of a laboratory-based testbed used to validate the performance of the proposed dual-decomposition-based peer-to-peer voltage control. The architecture of the setup consists of four layers: microgrid, control, communication, and monitoring. The key question motivating this research was whether distributed voltage control systems are a technically effective alternative to centralized ones. The results discussed in this paper show that distributed voltage control systems can indeed provide satisfactory regulation of the voltage profiles.

“…In this sense, the development of the innovation in ICT (e.g. artificial intelligence, the Internet of things, cloud technologies) brings a further digitalization of the distribution networks, where small producers connected in the low voltage levels gain prominence in the energy system (Mayer et al 2018). Based on the latter, the power system is evolving towards a digitalized system in which ICT is one more of its components, instead of a separate layer (Babazadeh and Nordström 2014).…”

“…Although the ICT employment and its development is crucial to increase awareness of a power system operation state, it is not exempt from vulnerabilities that could jeopardize its security (Mayer et al 2018). Therefore, the digitalization of the power system is accompanied by ICT related threats and risks that could lead to a power system failure, such as software errors, communication impairments, and even malicious intentional cyber-attacks.…”

“…The intermittent nature of the renewable energy sources, in addition to their massive decentralized installation in distribution networks, pushes the implementation of different controller strategies to optimally manage the network, which require the joint participation of a large set of controllable elements (VDE (FNN) 2016). Moreover, this management is accompanied by the introduction of a more complex information and communication technologies (ICT), as decentralized controllers act together based on the information exchange between them and remote substations in the power grid, turning the conventional power system into a digitalized one (Mayer et al 2018).…”

Systematic dynamic assessment for resilient operation of distribution networks

et al. 2018

The integration of decentralized energy resources is changing the ways distribution grids are being operated. Moreover, a major change is the implementation of active control strategies to adapt to the energy transition, such as voltage and reactive power in-feed control. Correspondingly, the dynamic nature of these controllers, the potential conflict of control objectives and uncertainty of these sources require frequent assessment of the system's dynamic behaviour. For this reason, this paper defines high level guidelines that allow simplifying Dynamic Security Assessment (DSA) in distribution networks, through the implementation of a methodology to determine the interactions of the network with its controllers. With this in mind, the focus of these guidelines is kept in reducing the computational effort, by reducing the number of dynamic simulations, as well as the amount of active controllers necessary for DSA. These guidelines are verified in an artificial 242-busbar distribution network, resulting in a reduction of 21,4% in number of dynamic simulations required for DSA.
