This paper proposes a practical approach to estimate the symmetrical short-circuit current (SCC) levels in overcurrent protection devices (OCPDs) installed on radial feeders for any penetration level of inverter-based distributed energy resources (DERs). The proposed method restores lost phase coordination by estimating SCC values and changing TMS OCPDs accordingly. is validated comparing resul...

Extreme weather events that are increasing in frequency and impact can cause extended disruptions to power grids. To increase the resilience of grids, focus is shifting from infrastructure hardening quickening restoration distribution systems after a disaster. One method achieve this through use microgrids leveraging distributed generation islanded mode. While much work has been done using for ...

Abstract We present an operation management controller for low voltage (LV) grids that coordinates a multitude of distributed energy resources (DER) in real time to maximize the utilization renewable production. It utilizes LTE radio network connects DERs distribution system operator. In our approach, utility functions are assigned DERs, and maximization is formulated as optimization problem. T...

Islanding operation is one of the main features of a MicroGrid (MG), which is realized regarding the presence of distributed energy resources (DERs). However, in order to deal with the control challenges, which an MG faces during island operation, particularly when the transition is associated with certain excessive load, an efficient control strategy is required. This paper introduces a Centra...

Mixed integer linear programming (MILP)–based distributed energy management for networked microgrids embedded modern distribution systems is proposed. Considering the diverse ownership of microgrids, resources (DERs) that interface directly with utilities and responsive loads, an alternating direction method multipliers–based framework was formulated scheduling by adjusting nodal price signals ...

The increasing integration of distributed energy resources (DERs) has provided the opportunity to deliver clean, and low-cost power for consumers. However, without appropriate coordination, injected by DERs can violate operational limits electricity distribution networks cause issues such as over-voltage lines congestion. Recently, promising concept Operating Envelopes (OEs) been introduced sup...

Demand-Side-Management (DSM) is one of the key applications in the future smart grid, creating a new degree of control in order to reduce losses and fluctuations caused by volatile distributed energy resources (DERs). To integrate the consumer side, several approaches like flexible tariffs, have been proposed and tested. However, many of these approaches not have been adopted widely yet because...

Integrated community energy systems (ICESs) are emerging as a modern development to re-organize local energy systems allowing simultaneous integration of distributed energy resources (DERs) and engagement of local communities. Although local energy initiatives, such as ICESs are rapidly emerging due to community objectives, such as cost and emission reductions as well as resiliency, assessment ...
