Non-Synthetic European Low Voltage Test System

In this work, a standard network made with real data obtained from the GIS (Geographical Information System) of the company, combined with real readings from smart meters is proposed. The authors not only provide (as additional material) the raw data obtained from the GIS and the Smart Meters but also the necessary MATLAB functions to automatically build the OpenDSS model, load it with the real data of the smart meters for 20 days and solve the power flow problem. The present system represents a real European low voltage urban distribution network with 10290 nodes, 8087 customers, 1138 power supplies, 136 fuses/breakers and 30 power transformers. The use and development of standard test systems has been critical for testing all kind of algorithms, operation procedures and planning purposes in transmission and distribution networks. With the irruption of the advance metering infrastructure based among others on smart meter technology, distribution systems suffered a drastic modernization in many regions of the world. The smart grid concept translated to the terminal distribution systems implies a drastic change of paradigm in the way these kind of systems have been planned and operated. Even when there exist several distribution test systems, most of them are synthetic and there is very few test feeder and networks representing European style distribution system. In this paper, a real comprehensive distribution test network representing a network of a typical town in Europe is presented. The model also has a provision to incorporate the smart meter data as obtained from the consumer's meter to study the distribution network states. This test network will provide the researchers a tool to work in algorithms and optimization of resources for European style distribution systems. The test network also includes the effect of neutral voltage in European style distribution network. The researchers provide together with the distribution company the raw data extracted from the GIS system and all the functions to convert the data into an OpenDSS model as well as the loads extracted from real smart meters representing 20 days. ' The function A_MakeNet.m is used prepare OpenDSS file and save it in folder RunDss The function B_MakeLoad.m is used to create the load-shape file from the smartmeter data extracted in file1, file2, etc. The OpenDSS code thus generated from raw-data is stored in folder /RunDss. The file 'Master.dss' is a default file and is also available in /RunMat/SrcDss. Power flow simulation can now be done by running C\_Run.m in MATLAB. It makes use of COM interface to do powerflow simulation in OpenDSS engine and stores the final result in /mat/bus.mat. The explanations about the data set, and all the functions are contained in a paper with the same title of the dataset that it is under review and will be linked to this dataset.
