“…Potentially, the option of grid reconfiguration could also be considered for thermal overloading. Multiple research works show the importance of meshed operation of the distribution grids, such as reduced line losses and increased RES penetration in the distribution grids [25,26]. Although this work does not consider a dynamic reconfiguration, such dynamic changes could have devastating effects on system stability, especially in the distribution grids.…”

The drastic increase in distributed energy resources (DERs) leads to challenges in the operation of distribution systems worldwide. While several solutions for grid monitoring and control are available on the market and in literature, this research is the first of its kind aiming to supervise the grid by providing a modular configurable unified hardware and software architecture. The control algorithms are configured using data models according to IEC 61850‐7‐3 and IEC 61850‐7‐4. The novel system architecture is a portable, modular and flexible architecture that aggregates smart grid control functions onto a standardised hardware platform, emphasising the need for hardware independence. The central controller contains several smart grid control functions and the various field devices are distributed across the distribution grid. This paper deals with the simulation of different real‐world distribution grids on the Real‐Time Simulator (RTS) and experimental verification of the control algorithms. Smart grid control functions such as Coordinated Voltage Control (CVC) and Optimal Power Flow (OPF) are experimentally verified on a German grid. The grid dynamics are compared when the central controller executes the CVC against the OPF implementations. The experimental results, advantages and challenges of each control are presented here. The results also showed the variation in grid behaviour when the control parameters were varied. The paper also shows that the algorithm and the choice of the control parameters depend upon the distribution grid's complexity and the system operator's individual needs. The results illustrate the potential of such a universal distribution automation solution for system operators worldwide.

“…Multiple DSOs in Germany operate meshed LV grids already. Research such as [29] exhibit the importance of the meshing of distribution grids while [30] discussed grid topology reconfiguration. This idea is also implemented in this model, where both branches in the Cigré LV networks are provided with an option to be connected at the end of the branches, if required.…”

“…The study involves the comparison of results from enumeration, constraints, and loops analysis methods. The authors in [21] develop a model that estimates the maximum penetration of DGs based on a steady state analysis. The approach uses some elements of an optimal power flow analysis and bus voltage and current flow limits to estimate the maximum allowable DG penetration at each node of the considered system.…”

Prospects of a Meshed Electrical Distribution System Featuring Large-Scale Variable Renewable Power

Electrical distribution system operators (DSOs) are facing an increasing number of challenges, largely as a result of the growing integration of distributed energy resources (DERs), such as photovoltaic (PV) and wind power. Amid global climate change and other energy-related concerns, the transformation of electrical distribution systems (EDSs) will most likely go ahead by modernizing distribution grids so that more DERs can be accommodated. Therefore, new operational strategies that aim to increase the flexibility of EDSs must be thought of and developed. This action is indispensable so that EDSs can seamlessly accommodate large amounts of intermittent renewable power. One plausible strategy that is worth considering is operating distribution systems in a meshed topology. The aim of this work is, therefore, related to the prospects of gradually adopting such a strategy. The analysis includes the additional level of flexibility that can be provided by operating distribution grids in a meshed manner, and the utilization level of variable renewable power. The distribution operational problem is formulated as a mixed integer linear programming approach in a stochastic framework. Numerical results reveal the multi-faceted benefits of operating distribution grids in a meshed manner. Such an operation scheme adds considerable flexibility to the system and leads to a more efficient utilization of variable renewable energy source (RES)-based distributed generation.
