“…Imbalance of three-phase line geometry was not taken into account. Ashourian developed a load flow program for unbalanced radial distribution networks, which can incorporate distributed energy resources as either a PV model or a PQ model [7]. Unbalanced line mutual couplings were considered and the voltage imbalance percentage was also examined.…”

In distribution power systems line transposition is not a common practice and phase loading levels are always changing. Therefore, perfect balance is never achieved at a distribution level. Non-transposed lines can cause unequal voltage drops between phases and this may be further exacerbated by uneven loads in each phase. Consequently, the voltage magnitude of a certain phase may suffer a severe decrease, breaching the lower voltage limit or unbalanced three-phase voltages at a remote bus may violate the percentage voltage imbalance accepted in the standards. This paper examines the mechanism of causing uneven voltage drops and investigates the impacts of unbalanced line configurations with different phase loading levels on network voltage imbalance. Methodologies are proposed to analyze voltage drops affected by line and load imbalance. Based on these methods, general guidelines are recommended to mitigate the voltage problems, which are useful for network analysis, planning and reconfiguration.

“…Before starting the main power-flow steps, the networks should be recognized. Reading network data, identifying all nodes beyond all the branches, constructing PV node sensitivity matrix ZV are some of these cases which were introduced by Shirmohammadi and Gosh in [4,5]. DGs as PQ operation are modeled constant PQ-load.…”

“…Energy efficiency, reduction of the power loss, reduced and deferral distribution investments, network (voltage) support, quality of supply improvement are some of the expected benefits of using DGs. Though, there are lot of advantageous of using DGs, but some concerned issues can be put to using DGs such as network protecting, load shedding, DG discarding, voltage supporting and bidirectional power flowing [1,5]. In order to development of ADN, appropriate operation and control, It should be concerned both DG operation and distribution network structures in power flow analysis which is an unavoidable tool for power system analysis.…”

Unbalance active distribution network (UADN) is the combination of unbalance distribution network (UDN) and distributed generations (DGs) such as gas generator, wind turbines, fuel cell, photovoltaic system, etc. Regarding to unbalance structure, different kinds of DGs models and bidirectional power flow, some network parameters such as amplitude voltage, voltage unbalance Factor (VUF), and power losses of network will alter accordingly. A suitable power flow analysis will provide a platform to analyse these behaviours in steady state condition. This paper offers appropriate method for handling DGs in a Power flow program which is developed using MATLAB® for practical unbalanced distribution network at Iran and investigate the impact of DG location and DG control mode (as PV and PQ mode) on voltage profile, reducing power loss and VUF.
