“…The feasibility of this proposed approach has been verified by using the analysis of an example and by proposing some measures to improve the comprehensive benefit. The experimental results indicate that the comprehensive benefit grade of the power distribution network planning project is "better" since the correlation degree is [0.024, 0.055] at j = 4 and the benefit grade variable eigenvalue is j * ∈ [3.33, 3.418] ∈ [3,4]. In brief, this paper offers a new method to solve similar problems of power distribution network construction projects.…”

“…Use j * ∈ [0, 1], [1,2], [2,3] and [3,4] to represent the comprehensive benefit level "poor", "fair", "good", and "better", respectively. In this paper, the benefit grade variable eigenvalue j * can be computed by using Equations (24) and (25), which is j * ∈ [3.33, 3.418] ∈ [3,4]. Therefore, the evaluation result indicates that the comprehensive benefit grade of the power distribution network planning project is "better", and there is a development trend towards "better".…”

“…How can we analyze the comprehensive benefit of urban distribution network planning quantitatively? The traditional assessment of an urban distribution network planning project has been mainly the individual evaluations, including reliability [1][2][3][4][5][6], safety [7], power quality [8], risk [9], and efficiency [10]. These studies tend to evaluate the technical level of the power distribution and subjectivity in terms of determining the weight, which previously affected the evaluation of the benefit of the power distribution network planning project, are all resolved.…”

Reasonable distribution network planning is an essential prerequisite of the economics and security of the future power grid. The comprehensive benefit evaluation of a distribution network planning project can make significant contributions towards guiding decisions during the planning scheme, the optimization of the distribution network structure, and the rational use of resources. In this paper, in light of the characteristics of the power distribution network, the comprehensive benefit evaluation index system is constructed considering the influencing factors of technical benefit, economic benefit, and social benefit. To eliminate the influence of subjective factors on the evaluation effects and the uncertainty of the influencing factors effectively, the improved interval analytic hierarchy process is employed to calculate the index weights more simply. Moreover, based on the traditional single-factor extension evaluation, this study proposes a multi-level extension assessment model to evaluate the comprehensive benefit of the power distribution network planning project. The model can not only identify the key factors that affect the evaluation effect of the power distribution network planning project, but also can predict the overall development trend of the project. Finally, using a specific urban distribution network planning project as an example, the findings indicate that the comprehensive benefit grade of this power distribution network planning project is "better" due to the benefit grade variable eigenvalue j * ∈ [3.33, 3.418] ∈ [3, 4], and illustrates that the model is credible and practical to achieve the comprehensive benefit evaluation of the power distribution network planning project.

“…Assumptions have to be made carefully, so the problems solution comes in a reasonable time and as close to the optimum as possible. There are plenty of algorithms proposed for network planning; most of them can be applied for planning radial networks, such as [7] - [11], and only a few for planning meshed networks, as [1], [5], [12] and [13].…”

Abstract.With the development of the Distributed Generation (DG), the role of power distribution networks becomes more and more important, and their configuration tends to change from radial to meshed. In this paper, algorithms for planning meshed networks are proposed. The problem of network planning has been transformed to an operational research problem. The algorithms are automated to reduce the planning time. Additional checks have been added to reduce the total length of the final network. A reliability assessment has been proposed to locate the weak spots of a network and to compare different solutions. Finally an application of the proposed algorithms is demonstrated.

This paper presents the correlation between the reliability and the weather scenario of Bangladesh Power System (BPS). Reliability of the power system is one of the major features of power quality. The variation of electrical demand above its base value is its common characteristic. The weather dependent variation of demand, especially where the weather is severe in nature, requires a significant reserve margin to ensure an acceptable level of reliability of the generation system. In Bangladesh, a significant difference in demands of winter and summer is generated due to weather variation. As a result the utility has to ensure an additional seasonal generation reserve capacity to maintain an acceptable level of reliability. This paper determines the correlation between the weather variables, namely temperature and relative humidity, and the reliability of Bangladesh Electricity Network. It also investigates the additional generation requirement during summer season to maintain an acceptable reliability level.
