In the Saudi Master Gas System Expansion project, portal frame of overhead line high-voltage substation was reformed. The safety and stability laying cable guaranteed through optimized design supporting structure production head. Good practical results have been obtained, construction quality period guaranteed. It provides a guiding operational statement for improved technology in substation.

An expert system for distribution planning is proposed in this paper. Choosing a best location of a distribution substation and grouping the various load points to be fed from a particular distribution substation has always been a concern to the distribution planners. Here in this paper the authors present a hybridization of K-means clustering method with fuzzy context aware decision algorithm ...

This paper presents the concept of the generalized power source in an active distribution network. After the energy storage system (ESS), distributed generators (DG), and demand-side controllable load are connected to the active distribution network, part of the system load can be undertaken by these ESS, DG, and controllable load instead of relying on the capacity of the substation, which grea...

In this paper, a model for hybrid transmission expansion planning (TEP) and reactive power planning (RPP) considering demand response (DR) model has been presented. In this study RPP considered by TEP for its effects on lines capacity and reduction of system expansion costs. On the other hand the expansion of the transmission system is an important subject, especially dealing with the new i...

this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...

The planning of wind farms exhibits several interesting problems. One of them is the minimum cost cable installation in wind farms. In this master thesis we regard a subproblem of it, namely the Substation Cable Installation Problem (SCIP). The SCIP deals with the minimum cable installation connecting wind turbines to a substation. It is therefore defined as follows: Given a set of coordinates ...

Emergency response operations in electric distribution systems involve a host of decision-making problems at the reliability, performance monitoring and evaluation, and contingency planning levels. Those operations include fault diagnosis, fault location, fault isolation, restoration, and repair. As the first of a two-part survey, this paper reviews optimization models and solution methodologie...

One ultimate goal of power network planning is to construct power systems that are environmentally friendly. However, it is still a challenging issue to efficiently consider environmental factors in power network planning problems due to the complexity and the diversity of environment. This paper presents a nonlinear approach to formulate the multi-dimensional spatial power network planning pro...
