Electric Utility

It proposes a lossless and stateless compression method for IEC 61850 Sampled Values flows. A set of bitmaps is introduced to indicate the size in bytes of the sampled currents and voltages, and to flag the presence or absence of the Quality field. The method has been evaluated for different profiles, and it can provide bandwidth savings between 30 and 52%, with a very low computational cost as a counterpart. It has been implemented and tested in two different hardware platforms, with traffic generated by a Merging Unit.

This dataset is created by an experimental setup of a DC-PV -Battery-based grid-connected distributed generation system. This dataset is split into four parts such as irradiance, and temperature, which were measured by a meteorological station, and lastly, PV output current and voltage acquired by an inverter. Furthermore, we can have a chance to obtain the output PV power by multiplying current and voltage. The dataset has 288 elements for one day as a time series since the station obtains the data within five minutes. However, the whole dataset has three days of data with 864 elements.

This data provides the simulation parameters and the optimal results of the comprehensive active distribution network (ADN) expansion planning model that includes both wire alternatives (WAs) and nonwire alternatives (NWAs). The primary motivation is to find the optimal sizing and siting of NWAs while considering WAs such that the ADN’s dynamically growing electrical load and electrical vehicle (EV) demand are met while maintaining network limits.
