Abstract
The increasing demand for clean and nonfossil energy has escalated the integration of renewable power sources into the distribution system. Renewable distributed generators (DGs) have the potential to reduce the environmental impact when the integration into the distribution system is carefully optimized. However, serious technical issues will be raised when the integration is not properly implemented. This chapter presents optimal siting and sizing of renewable DG units within distribution systems. Both deterministic and probabilistic models of renewable-based DG units will be discussed in details along with characteristics of well-known renewable generators. The effects of DGs on...

Abstract
Electric distribution system is one of the most important parts of power systems owing to delivering electricity to consumers. The major amount of losses in a power system is in distribution level. Optimal distributed generation (DG) placement and sizing have a significant effect on power loss reduction in distribution systems. In this paper, a mixed integer conic programming (MICP) approach is presented to solve the problem of DG placement, sizing, and hourly generation with the aim of reducing power loss and costs in radial distribution systems. The costs include both investment and operational costs of DGs. Hourly load variations are considered in the model. To verify the effectiveness of...

Abstract
One of the beneficial impacts of Distributed generation (DG) units on electrical network is power loss reduction in the distribution feeder on which DG is located. In this paper the effect of DG on power losses of a distribution feeder with a combination of uniformly distributed and lumped loads is investigated, and a mathematical model of power loss reduction as a function of DG and the feeder parameters is extracted. Then, based on the derived formula, optimum conditions of utilizing and locating the DG units are obtained. © 2006 IEEE
Efficient immune-GA method for DNOs in sizing and placement of distributed generation units
, Article European Transactions on Electrical Power ; Volume 21, Issue 3 , 2011 , Pages 1361-1375 ; 1430144X (ISSN) ; Ehsan, M ; Sharif University of Technology
Abstract
This paper proposes a hybrid heuristic optimization method based on genetic algorithm and immune systems to maximize the benefits of Distribution Network Operators (DNOs) accrued due to sizing and placement of Distributed Generation (DG) units in distribution networks. The effects of DG units in reducing the reinforcement costs and active power losses of distribution network have been investigated. In the presented method, the integration of DG units in distribution network is done considering both technical and economical aspects. The strength of the proposed method is evaluated by applying it on a small and a realistic large scale distribution network and the results are compared with...
