is work is dedicated to the economic scheduling of the required electric stations in the upcoming 10-year long-term plan. e
calculation of the required electric stations is carried out by estimating the yearly consumption of electricity over a long-time plan
and then determining the required number of stations. e aim is to minimize the total establishing and operating costs of the
stations based on a mathematical programming model with nonlinear objective function and integer decision variables. e
introduced model is applied for a real practical case study to conclude the number of yearly constructed stations over a long-term
plan in the electricity sector in Jeddah City, Saudi Arabia. e current planning method is based only on intuition by constructing
the same number of required stations in each year without searching for better solutions. To solve the introduced mathematical
model, a novel recent gaining sharing knowledge-based algorithm, named GSK, has been used. e Augmented Lagrangian
Method (ALM) is applied to transform the constrained formulation to become unconstrained with penalization to the objective
function. According to the obtained results of the real case study, the proposed GSK with ALM approved an ability to solve this
case with respect to convergence, efficiency, quality, and robustness.
1.Introduction
In the coming years, the population projection is expected to
rise worldwide, and this should be accomplished through an
enough increase in the supply of electricity to cover the
anticipated higher demand.
Expert opinions suggest that the expected load demand
is a key factor needed for preparing the potential power
needs. Planning authorities around the world state that the
forecast of the population is to be continuously increasing
[1]. is increase should be balanced by an enough increase
in the supply of electricity.
Since electricity demand is in a direct relation to the
anticipated population growth, the electricity company
should support the current network by installing addi-
tional stations to meet the growing demand [2]. e in-
frastructure utilities demand such as water, electricity,
wastewater, and communication would surpass propor-
tion to the population growth and the expansion of new
urban areas. e responsible authorities are required to
support the corresponding networks by installing new
stations to meet the growing demand and prevent busi-
ness disruption and economic losses due to electricity
failures [3].
