“…The CRITIC method uses a set of matrix calculations to analyze a data set that covers the different cases under analysis and all the decision criteria to be considered. The objective is to minimize the criteria values and select the best alternative in a weighted manner [11,[23][24][25][26].…”

The growth in the demand for electrical energy, which is driven by the constant growth of the metropolises and the expansion of the productive capacities of the industrial sector, entails the inevitable development of the electrical system to satisfy all the required demands in a convenient, efficient, and reliable manner. In this scenario, power distribution companies will continue to need to expand their electrical systems in the short and medium term to obtain the lowest investment and operating prices for the period considered in the analysis horizon. The expansion of the system can be projected statically or dynamically, which depends on the criteria that each distributor, in turn, applies in their expansion projects. Multi-criteria decision making can provide deeper analysis perspectives considering infinite possibilities for optimal network sizing and the technical, operational, quality of service, and even system reliability factors. This research proposes a multi-criteria decision technique based on the CRITIC method to determine the optimal design of an electrical distribution system. For this purpose, several design scenarios are defined with different types of electrical conductors, and the power flows are calculated in each. From these simulations, the results obtained in voltage profiles, namely active and reactive power losses, current levels, and the costs associated with the conductors used, are recorded. With the multi-criteria technique, the winning alternative is the design scenario containing the best joint solutions for the analysis variables. The proposed methodology is validated in an IEEE 34-bar test system. The Matpower tool, available through Matlab, generates power flows for each proposed design case. The results obtained in the analysis variables are generated and stored in a decision matrix of 210 alternatives. The proposed method represents a novel and powerful alternative for design proposals of distribution systems considering quality, efficiency, and cost criteria.

“…The issue of diminution of power losses and strengthening voltage distribution through reconfiguration was not addressed in this method [1]. The procedure for changing the status of switches is known as reconfiguration, and its aim is to shorten losses and strengthen voltage distribution [2], [3]. The optimisation challenge is solved with a heap-based optimizer that employs a corporate rank hierarchy to obtain the best radial distribution networks (RDN).…”

<p>Restoration of service during faults to healthy zones and the minimization of true or real power losses are the main aspects of the satisfactory operation of an electrical distribution system (EDS). These objectives can be achieved with artificially intelligent optimisation techniques through electrical distribution system reconfiguration. The restoration of service is an important part of ensuring a stable power supply. If there is a fault with the EDS, the damaged zone is separated, and the healthy system is restored without breaching limitations. In the distribution system, ohmic losses are 25-35%. It is essential to reconfigure the system toreduce these losses. In this paper, a hybrid artificial rabbits’optimisation and improved mayfly optimisation (ARO-IMO) technique is adopted for restoration of serviceand loss minimization. The method being suggested will be carried out on an IEEE 4-feeder network for restoration of service and on IEEE 33 and69 radial distribution networks (RDN) for diminution of losses.</p>

“…Achieving this demands significant investments that the electric power distributors must assume to guarantee the desired reliability indicators. These indicators for level 3 of Reliability in electric power systems (distribution level) are known as Average Energy Not Supplied (AENS), System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and Customer Average Interruption Duration Index (CAIDI) [5], [6]. Measures to reduce failure rates and interruption repair times require considerable investment in human, material, and technical resources for repair and preventive and corrective maintenance [7].…”

“…In this chapter, the multicriteria decision methodology will be presented as an alternative to solving engineering problems that require an optimal solution. The multicriteria method allows for solving optimization problems that depend on multiple variables considering the conflict that may exist between them [1], [6]. Multicriteria, multi-objective optimization, or multicriteria decision-making methods solve optimization problems involving multiple conflicting objectives or criteria.…”
