Proper location of DGs in power systems is important for obtaining their maximum potential benefits. This paper deals with DG for minimizing active power loss and D-statcom for reactive power loss minimization is considered. The proper siting of DG and D-statcom is a recently developed combination with the aim of reducing line loss in a radial distribution system. Loss Sensitivity Factor (LSF) ...

The power world is sauntering towards ecofriendly distributed generation (DG), their integration into the distribution network postures challenges to existing load flow techniques. This paper is concerned with developing models of various types of wind turbine generating systems (WTGSs) used as distributed generation (DG) sources and demonstrating their application for steady state analysis. As...

This paper reviews different approaches for unbalanced load flow analysis within a distribution network, especially in a microgrid (MG). Models of untransposed distribution lines and unbalanced loads are considered for each methodology, as these are common in a MG scenario. Various commercial software packages are also investigated and assessed in terms of solving the power flow of the MGs and ...

This paper introduces the modeling of Static Series Voltage Regulator (SSVR) in the load flow calculations for steady-state voltage compensation and loss reduction. For this approach, an accurate model for SSVR is derived to use in load flow calculations. The rating of this device as well as direction of required reactive power injection to compensate voltage to the desired value (1) is derived...

Load characteristics play an important role in distribution systems, which are traditionally designed to supply peak load; hence, decreasing this peak can considerably reduce overall grid costs. Basic components of smart grids such as smart meters allow two-way communication between the utilities and customers; in this context, controllable smart loads are being introduced, which allow developi...

In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...

In this paper, load flow solution is obtained for radial distribution system using a new algorithm. Network topology is exploited to build two matrices for obtaining load flow solution of radial distribution system. Effective load at each node consists of two parts. Part one is the sum of all active and reactive powers connected to nodes beyond a particular node. And part two is the power loss ...

With the implementation of competitive electricity supply system all over the world, there is the need of optimal utilization of the existing generation sources at the same time to curtail the generation from the conventional power plants and add the renewable sources generation looking into the environmental concern and limitation of the fossil fuels. This has lead to the motivation for the st...
