Optimal distribution substation placement is one of the major components of optimal distribution system planning projects. In this paper optimal substation placement problem is solved using Imperialist Competitive Algorithm (ICA) as a new developed heuristic optimization algorithm. This procedure gives the optimal size, site and installation time of medium voltage substation, using their relate...

The connection points between MV and LV distribution networks are MV substations. Optimal sitting, sizing and timing of MV substation placement is the major planning problem in MV-LV distribution system planning projects. In this paper the optimal MV substation placement problem is solved using Imperialist Competitive Algorithm (ICA) as a new developed heuristic optimization algorithm. This pro...

ABSTACT This paper presents a new method for solving Substation Expansion Planning (SEP) problem using three basic algorithms in fuzzy clustering. Clustering algorithms are mainly associated with distance functions and measure dissimilarities of data set in different clusters. It is equivalent to measure similarities of data in a cluster. That is, a lot of varieties exist to find and create suc...

presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...

A new method to solve the single and multi-objective distribution expansion planning problems including DG is investigated in this paper. The sizing and placement of DG as well as the required power of the main grid would be optimized using proposed method to meet the demand. Binary Particle Swarm Optimization (BPSO) algorithm is used to solve the optimization problem for three objective functi...

network expansion studies normally offer new power lines, new substations or expansion of existing substations. they are generally proposed based on technical requirements, but financial restrictions are not considered. because of financial restrictions, ranking of network expansion plans is required. in this paper an algorithm for such ranking, based on technical and financial view points and ...
