Solid power system planning is fundamental to the safety, reliability and economy of power system operation. In the deregulated power grid environments, power grid planners not only have to handle massive geographic data, power equipment parameter data and grid operational data, but also have to solve very complex decision-making problems when they are committing power grid planning. Thus, it is necessary...
After the occurrence of grid emergency, fast and accurate evaluation of harmful levels of the incident and identification of disaster-level are the basis for activate contingency plans, reasonable allocation of resources and thus crisis management. Combined with the practical, the paper sets up grading evaluation index system of power emergency from the power grid losses, the user lossed and accident...
The present study, firstly, puts forth a comprehensive and reasonable reliability assessing theory system directing at fuzzy layers and the incomprehensive factors of current distribution network. Next, the four major characteristics influencing reliability of the distribution system have been defined and research has been conducted on grade one and grade two as well as basic index involving those...
Recently, most methods for replacement decision-making of electrical equipments in distribution network have some limitations like insufficient concern with reliability and economy. As a solution, a new method considering both network reliability and equipment economy is presented in this paper. It consists of two parts: equipment-replacing necessity decision-making, which is used for all electrical...
This paper reviews literature that identifies the need for decision-making associated with the design and operation of electric power grids including microgrids. In particular, it examines the current applications of analytic hierarchy process (AHP) as the decision-making tool for electric power grids and microgrids. AHP is a decision making tool based on expert judgments that has been successfully...
