A New Approach for Substation Expansion Planning

Abstract

Substation expansion planning (SEP), as a major module of power system planning modules, is addressed in this paper. For long-term transmission SEP, a new approach based on a genetic algorithm (GA) optimization tool is proposed, in which by defining appropriate objective function and various constraints, new as well as expansion of existing substation requirements are determined. The proposed algorithm is successfully tested for the Iranian Power Grid in 2011.Index Terms-Genetic algorithm (GA), optimization, power system planning, substation expansion planning (SEP).

Power substation location selection using fuzzy analytic hierarchy process and PROMETHEE: A case study from Bangladesh

“…Initially a literature review was conducted to identify various criteria and sub-criteria considered by location researchers and DMs [1,2,5,8,10,19,21,22]. Fourteen specialists from engineering, medical and academic background with Bachelor degree and average work experiences of 13 years in this field were chosen to form the decision team.…”

“…Carrano et al [4] combined quasi-Newton and GA for the optimal expansion of energy distribution systems. Sepasian et al [8] also proposed GA for longterm transmission substation expansion planning (SEP). Farrokhifar et al [2] developed a comprehensive cost function for the problem of optimal location of sub-transmission substations considering technical constraints and economical parameters.…”

Substation and transmission line expansion planning using Adaptive Tabu search algorithm

“…Reference [1] proposed the simultaneous SEP and TEP algorithm by using DC optimal power flow, while Mixed integer programming is presented in [2]. Reference [3] proposed the SEP algorithm by using genetic algorithm method. Reference [4] presented TEP based on genetic algorithm with reliability consideration.…”

“…In references [1], [2], [3] and [4], the solutions are found from the list of candidates. References [2] and [3] have an algorithm to find the candidate TSs.…”

Converter placement in the interconnection of railway power grid and public power grid based on cost-reliability approach

“…From power system point of view, several literatures investigate the problem of transmission capacity expansion and substation expansion planning [3][4][5]. But, the problem of interconnection expansion planning between two different networks is poorly investigated.…”
