Abstract
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.
Highlights
The resulting model is of a stochastic mixed integer linear programming type, whose objective function is minimized to achieve the optimal operation of a system that features large quantities of variable renewable energy sources (vRESs) power, while respecting a number of technical, economic, and environmental constraints
The analysis is carried out to study the operational flexibility that can be provided by operating vRES-rich distribution grids in a meshed manner
The analysis includes the impact of such a scheme on the use and integration of vRESs
Summary
Distribution power systems are experiencing massive transformations that are buoyed by the increasing need to integrate more variable renewable-type distributed generations (DGs) This means that distribution grids will be equipped with the necessary tools to enable bidirectional power flows, which is contrary to their traditional setup [1,2,3,4,5,6,7]. When a fault occurs in the system, fast de-loopers can be deployed to quickly switch from a meshed to a radial topology so that conventional protection devices can properly act Another enabling technology with regards to a meshed topology’s operation is Fault Current Limits (FCLs) [18]. The operation of distribution networks in a meshed manner may become the norm in the near future
