DER and load allocation for an unbalanced distribution networks state estimator

This paper describes the work done in the 3PHASE project, regarding the development of a state estimator for distribution networks handling substantial integration of DER (Distributed Energy Resources), AMI (Advanced Metering Infrastructure) data and unbalanced and asymmetrical configurations. The load and DER power allocation presented here, as part of a DMS system, constitutes a first estimation of the network, assuming an extreme importance for other studies as it helps solve the lack of m...

Innovative Smart Grid Solutions for Network Planning and Access

Smart Grids are the cornerstone for Distribution System Operators transformation. Having new solutions to deal with historical and future problems is key to ensure a smooth transition to an advanced power system that not only integrate a large share of renewables and distributed energy resources (e.g. storage, electrical vehicles), but also requires efficient operation, better planning and exceptional customer service. EDP Distribuição is at the forefront of this transformation, as it is deve...

Using LV Real-Time Data for Pseudo-Measurements Generation in MV Distribution Networks

This paper presents a new method to generate pseudo-measurements of different electrical quantities for distribution secondary substations. The idea is to take advantage of the stronger correlation that exists between electrical variables in a given MV/LV substation and the correspondent downstream network. Autoencoders trained with historical data are integrated on an optimisation algorithm, together with real-time metering information of the LV network, for accurately estimate pseudo-measur...

Advanced System Architecture and Algorithms for Smart Distribution Grids: The Sustainable Approach

In order to allow large scale integration of Distributed Energy Resources in a secure and efficient way, the EU Project SuSTAINABLE designed a reference architecture for management and control of the distribution system as a whole. This novel architecture is based on the hierarchical architecture already deployed in the InovGrid test site in Évora, Portugal InovCity. This will require the development of specific algorithms and tools to support distribution system operation that are able to ex...
