Distributed Energy Resources (DER) has introduced new challenges in regulating the power system frequency. These challenges are mainly due to its intermittent power generation/load demand, which consequently results in stability problem of power system. There are very few articles in literature that discuss about the stability issues and dynamic control of DER. Hence, in this article an attempt has...
In this paper, the mathematical Analysis of UPQC which is combination of Shunt-APF and Series-APF in distribution power systems discussed. It is more extensive by adding a series VSC from feeder to feeder. UPQC is added in each line coming from various substations to mitigate different power quality problems to maintain good voltage profile at supply side and the load end current disturbances in distribution...
This paper presents and validates the balanced radial distribution network (RDN) Matlab/Simulink model. The validation of Simulink model is carried out by comparing node voltages, total active and reactive power loss of balanced RDN with an existing vector distribution load flow (VDLF) method. The Simulink model is very helpful for proper sizing of distributed generation (DG) in RDN in considering...
This paper concerns the changing dynamics of planning and operations of the North American Bulk Power System (BPS) due to the confluence of trends in increasing Variable Energy Resources (VER), the retirement of conventional power plants and the current and future environmental regulations. The work presented is part of a larger effort by the North American Electric Reliability Corporation (NERC)...
In this paper, the impact of models of voltage dependent loads have been discussed for the analysis of URDS (Unbalanced Radial Distribution Systems) for the future expansion of electrical distribution network. Load growth need to consider for better operation of the distribution system. Minimum voltage, system real and reactive power losses, number of iterations and CPU time are calculated with different...
