Restoration of radial distribution networks

European Transactions on Electrical Power, 1997
AbstractThis paper describes an efficient and robust heuristic method for restoration of radial distribution networks for the purpose of re‐constructing normal operating conditions. Due to its computational efficiency, this approach can be used in both the planning and operating environments. Important implementary aspects of methodology and results of

State estimation algorithm for radial distribution networks

2017 XXVI International Conference on Information, Communication and Automation Technologies (ICAT), 2017
State estimation is a basic function, which results are used in almost all other functions for the analysis, management and planning of distribution networks. The paper describes the process of load calibration that is one of the basic steps in the process of state estimation in the distribution network.

Optimal Capacitor Placement in Radial Distribution Networks

IEEE Power Engineering Review, 2001
The capacitor placement (replacement) problem for radial distribution networks determines capacitor types, sizes, locations, and control schemes. Optimal capacitor placement is a hard combinatorial problem that can be formulated as a mixed integer nonlinear program.

Impact of increased distributed photovoltaic generation on radial distribution networks

2016 International Conference on Control, Decision and Information Technologies (CoDIT), 2016
In this paper, the analysis is carried out over distribution test systems. The analyses show that voltage variation problems occur in different nodes of the distribution networks with an increase of penetration level. However, proper selection of dispersion level can improve the voltage profile and decrease losses of the distribution systems. Depending

Voltage Stability in Radial Distribution Networks

2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 2019
Voltage stability is a matter adressed mainly in transmission network. In distribution network the focus must consider a few variations with the traditional model, specially the well-known issues of unbalance and the R/X relation that causes the jacobian matrix bad condition. The length of the feeder is another matter among peculiarities of the system.

Optimal insulation in radial distribution networks

Electric Power Systems Research, 1996
This paper presents a model of unsupplied energy reduction achieved by the insulation of specified parts of lines belonging to a radial distribution system. An optimization procedure is developed that defines which network sections should be insulated to obtain the greatest possible reliability enhancement, subject to investment cost limitation, or to ...

Radial versus primary network distribution

Electrical Engineering, 1934
In this paper is set forth the comparative investment indistribution plant necessary over a 10-year period to provide for load increase in a typical section of Chicago, either by means of the existing radial feeder system or a primary network system. The results show that, in terms of both total new investment and accumulated annual costs, the use of ...

Impact of distribution STATCOM allocation on radial distribution networks

2015 International Conference on Energy, Power and Environment: Towards Sustainable Growth (ICEPE), 2015
In this paper, the impact of distribution STATCOM (DSTATCOM) allocation on radial distribution systems is presented. A DSTATCOM is placed at each bus of a distribution network, one at a time, and its impact on system power loss is investigated. A new mathematical modelling for DSTATCOM is done to suitably incorporate it in the forward-backward sweep ...

Optimal Location of Distributed Generators in a Radial Distribution Network

2020
Electrical power loss and low-voltage profile represent loss of revenue to power utility providers as well as electricity end users. Utility providers therefore need to take steps towards minimizing power losses and ensure appreciable bus voltage at the load ends. There are various methods for improving the performance of a power network.

Allocating Loss with Network Reconfiguration in Radial Distribution Networks

2018 International Conference on Recent Innovations in Electrical, Electronics & Communication Engineering (ICRIEECE), 2018
In this paper, loss is allocated to the various nodes in a radial distribution network when the network undergoes reconfiguration to reduce the overall power loss. A new method of loss allocation is formulated using the bus identification scheme described.
