Distributed Generator Placement And Sizing in Unbalanced Radial Distribution System
Distributed Generation & Alternative Energy Journal, 2010To minimize power losses, it is important to determine the locationand size of local generators to be placed in unbalanced power distribu-tion systems. Because of some inherent features of unbalanced distribu-tion systems, such as radial structure, large number of nodes, and awide range of X/R ratios, the conventional techniques developed forthe ...

Intelligent control for a radial distribution system with distributed generation
2011 International Conference on Energy, Automation and Signal, 2011Now days the Distribution Network Organizations (DNO's) have set some rules to maintain the voltage at a specified level to control the increase of voltage variations and controls the power factor. The main objective of this paper is that in cases of weak networks the voltage level is maintained by the distributed generation (DG) by importing or ...

Distribution systems—basic techniques and radial networks
1984Over the past few decades distribution systems have received considerably less of the attention devoted to reliability modelling and evaluation than have generating systems. The main reasons for this are that generating stations are individually very capital intensive and that generation inadequacy can have widespread catastrophic consequences for both

Optimal Sizing of Distributed Generation Placed on Radial Distribution Systems
Electric Power Components and Systems, 2010Abstract Distribution network planning identifies the least cost network investment that satisfies load growth requirements without violating any system and operational constraints. Power injections from distributed generation change network power flows, modifying energy losses.

Overcurrent protection issues for radial distribution systems with distributed generators
2009 IEEE Power & Energy Society General Meeting, 2009The integration of distributed generators (DGs) into distribution systems is being proposed as a solution to meet increasing load demands and to utilize more renewable energy. Existing overprotection schemes must be modified to address the new system characteristics of radial distribution systems with DGs. Minimum “off-the-shelf” overcurrent protection

Distributed generation for line loss reduction in radial distribution system
2012 International Conference on Emerging Trends in Electrical Engineering and Energy Management (ICETEEEM), 2012This paper presents a method to select the load buses for the placement of distributed generation (DG) based on loss reduction and voltage improvement sensitivity of the system. The DG placement and its precise size to reduce the line loss has been considered and evaluated.

Decentralized control of distributed energy resources in radial distribution systems
2016 IEEE International Conference on Smart Grid Communications (SmartGridComm), 2016We consider the decentralized control of radial distribution systems with controllable photovoltaic inverters and storage devices. For such systems, we consider the problem of designing controllers that minimize the expected cost of meeting demand, while respecting distribution system and resource constraints.

Determining the impact of distributed generation on power systems. I. Radial distribution systems
2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002Distributed generation (DG) has much potential to improve distribution system performance and it should be encouraged. However, distribution system designs and operating practices are normally based on radial power flows and this creates a special challenge to the successful introduction of distributed generation.

IEEE Power Engineering Society General Meeting, 2004., 2003
To improve system reliability for radial distribution systems with distributed generation (DG) under fault conditions, switch placement schemes are proposed to form self-supported areas after fault isolation. Customer priority is also considered in this problem.

Optimal conductor selection in planning radial distribution systems
IEEE Transactions on Power Systems, 1988A fast algorithm to help in the selection of proper conductors for feeder expansion plans is presented. The optimal conductor type is determined for each feeder segment in order to maintain an acceptable voltage profile along the entire feeder, minimizing capital investments and the cost of feeder losses.
