“…Such generators typically are installed at the distribution system level, so they are driving the scientific community to deal with new problems of planning and managing distribution networks in normal and abnormal operating conditions in the presence of the so-called distributed generation (DG). The new challenges for researchers and managers involve the complete change of the distribution paradigm from passive networks with unidirectional, top-down energy flows to active networks with bi-directional energy flows [1][2][3][4].…”

Abstract:In this paper, we analysed the growing penetration of generating units from renewable energy sources in transmission power systems. Among the possible effects of the interaction of distributed generation (DG) with transmission systems, we considered the abnormal operating conditions caused by short circuits in the transmission systems and the resulting voltage sags that occur in the network. A systematic method is presented for analysing the voltage sag behaviour of any transmission system in which large DG units are connected to the transmission system by means of High Voltage/Medium Voltage (HV/MV) stations. The method proposed for obtaining the voltage sags is the fault position method (FPM), from which we derived a graphical visualization of the during-fault voltage (DFV) matrix as a valuable tool to obtain an immediate measure of the propagation of voltage sags in the network. The results obtained were based on a portion of a real transmission system. The system that we considered is an actual portion of the Italian transmission system, and all of the quantities we used were obtained from the data of the Transmission system operator (TSO).

“…However, as the penetration levels of these distributed generators (DG) continue to grow to the extent that it is affecting the normal operation of a power system [1][2][3][4]. The large-scale real power injection by DG systems at certain locations on power transmission/distribution networks can violate the power system constraints, such as, excessive feeder voltage rise [4].…”

“…The reliability impact of these resources is an important aspect that needs to be assessed because their large scale of penetration may affect the proper operation of the power system distribution networks [1][2][3][4][5]. These plants inject active power into the network, and so they may cause fluctuations in the power injected as they depend mainly on fluctuating natural resources or they may cause voltage variations [6][7][8][9][10].…”
