Real European Low Voltage Test Network for Smart Grid Applications

Abstract

With the rise in smart grid implementation in Europe, the requirement of a real test system where different smart grid application can be tested is inevitable. Most of the existing test feeders or networks are based on North American style distribution system. There are very few test systems representing the European style but they are not complete and do not represent actual European style network and feeder. In this thesis, changes are proposed in the existing model for IEEE European LV test feeder to make it represent an actual European style feeder. The proposed modified IEEE European LV test feeder will have four-wires model instead of three. The European distribution networks have TT grounding neutral, which is isolated from the ground of consumers. So the return path of all neutral current is through the neutral conductor, which gives rise in neutral voltage. The concept of neutral voltage is neglected in the original test bus system which we have included in modified test feeder. In the second part, a methodology is discussed to convert GIS data obtained from EDP Spain to OpenDSS model using the set of codes. Further, a comprehensive European test network with 30 LV substations, 10290 buses and 8087 load point with smart meter data of 20 days has been proposed to represent the European style LV distribution system. This test system provides the possibility to reconfigure LV network as well as provides an important base for economic and technical studies in large scale Network.
