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

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.

Demand response in radial distribution networks: Distributed algorithm

2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012
Demand response has recently become a topic of active research. Most of work however considers only the balance between aggregate load and supply, and abstracts away the underlying power network. In this paper, we study demand response in a radial distribution network, by formulating it as an optimal power flow problem that maximizes the aggregate user

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 ...

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.

Network pricing for high voltage radial distribution networks

2011 IEEE Power and Energy Society General Meeting, 2011
Network pricing is considered to be one of the effective ways to guide future demand and generation connection in distribution networks so as to encourage more efficient network usage and guide optimal development. Presently, the Distribution Reinforce Model (DRM) is utilized for High Voltage (HV) and/or Low Voltage (LV) distribution network pricing in

Voltage collapse proximity indicators for radial distribution networks

2007 9th International Conference on Electrical Power Quality and Utilisation, 2007
Based on the single-line equivalent system of a radial distribution network, two simple methods to evaluate two efficient voltage collapse proximity indicators are presented and discussed. The two methods differ on the determination of the parameters which define the equivalent system from which the indicators are derived.

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 ...

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.

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 ...
