Decentralized Optimal Power Flow for Low Voltage DC grids: An algorithm for online optimization on a physical environment

The DC Optimal Power Flow (DC-OPF) problem is a widely-studied topic in the field of power systems. A solution to the problem consists of minimizing the running costs of the power system, through defining the optimal operating state for each entity in the system, while adhering to a set of physical constraints. A lot of research has been...

Design of a protection scheme for an off-grid microgrid with inverter-based power sources

The electrical infrastructure is evolving, shifting into a decentralized grid that allows the incorporation of renewable energies and mitigates the negative effects of power outages. It is predicted that this will lead to a substantial increase in the amount of microgrids deployed worldwide. Especially in locationswith a less reliable grid, the...

Stability and Decentralized Control of Plug-and-Play DC Distribution Grids

Changes in distribution grids pose significant challenges with respect to the control and management of these grids. Stability and decentralized control are vital to ensure the availability and accessibility of plug-and-play dc distribution grids that are (temporarily) without communication. Therefore, this paper presents guidelines for these...

Toward the Universal DC Distribution System

AbstractDue to an increasing number of power generation units and load devices operating with direct current (DC) at distribution level, there is a potential benefit of leading efforts toward building a DC distribution system. However, the implementation of DC distribution systems faces important challenges, including the market inertia of AC...

A Smart Home: Main Control Unit and Nodes

In order to cope with various supplies and loads in an autonomous microgrid, a system of sensors and a control unit was developed. The goals of this system are to cope efficiently in the event of an energy supply shortage, and to prevent such events as much as possible. To achieve these goals, the aim was to manage energy in the system as...
