State Estimation in Medium Voltage Distribution Networks

Transition from fossil fuels to sustainable sources of energy like wind and solar is the need of the hour. All over the globe, plans are in motion to achieve this goal. This implies addition of new elements to the grid in the form of Distributed Energy Resources (DERs). These affect the working of distribution grids and to ensure reliable as...

Modelling and flexibility assessment for operational studies of future active distribution networks

At present, the energy transition is increasingly being driven by the integration of renewable energy into the grid. However, this weather-dependent energy generation imposes challenges to the system operators since the deviations between the forecasted and the actual generation keep increasing due to this intermittent generation. Moreover, new...

Digital Twin Application for Congestion Management in Distribution Network

High penetration of rooftop PV generation in the distribution network increases the variability of power flows and the frequency of network and hence congestions occurs at various network locations of the network. Congestions have various defects such as it deteriorates network performance, power quality and therefore can lead to a shutdown by...

Flexibility trading for aggregators of electrical vehicles within the Universal Smart Energy Framework: A research on trading flexibility in a USEF compliant market at distribution level for aggregators of electrical vehicles

Increased use of the distribution grid due to the uptake of distributed energy resources and the expected penetrations of Electrical Vehicles (EVs) could lead to congestion problems in the distribution grid. Congestion refers to issues related to the overheating of components or voltage issues in the distribution network. Avoiding these issues...

A sustainable procurement policy proposal for distribution system operators

The environmental and social impact of the energy generation and distribution industry on the biosphere is negative or unknown due to a lack of supply chain transparency. For electricity and gas distribution system operators (DSOs), the opportunity to contribute significantly to more environmental and social sustainable development in the energy...

The distribution system operator as flexibility manager of distributed energy resources: A spreadsheet based simulation study on the case of the Netherlands

Within the Netherlands, house owners set up projects in which all houses within a neighbourhood are collectively renovated and equipped with distributed energy resources (DERs) at the same time. These projects are called ‘neighbourhood distributed energy resource projects’ (NDPs). As some of the equipped DERs electrify much of the heating...

The DSO and residential energy efficiency; a good match? An analysis of the potential role of a distribution system operator in the residential energy efficiency field

Residential energy efficiency is an increasingly important notion in light of the increasing energy prices and increased focus on an environmentally sustainable society. DSO’s have the potential to make a great contribution to the field based on their unique market position, but are held back by regulation and market opposition. This article...
