Abstract
Electric power has become an essential measure of the structure of modern society with most of today’s daily activity based on the proposition that the desired electric power constantly exists. In The Electrical Distribution System (EDS), each component is essential to the process of distributing power from the site where it is generated then supplied to the customer who utilizes it. Distribution system plays an utmost role in providing the electrical energy from its generation point to the consumers’ end by the use of transmission system. Since the R/X -Where R is the Resistance and X denotes for the impedance- ratio in the distribution network is high, the losses in the distribution system is more. The DGs employed in this work is a mix of Photovoltaic panels (PVs) for active power compensation and capacitors for reactive power compensation. Location, range and type of capacitors used in the system manipulate the amount of compensation provided by the capacitors. To decide the location and size of the DGs, a load flow will be used and losses in the radial network are considered. The backward-forward sweep load flow technique is used on the IEEE 69 bus standard network. Also, the Genetic algorithm, antlion technique and Cuckoo search algorithm (CS) are used as optimization techniques. The results are tested on the IEEE 69-bus standard test network to validate the proposed algorithms. The proposed algorithms showed enhanced results compared to the genetic algorithms.

The other section will be a table of comparison between the Genetic Algorithm (GA) in finding the size and location of the Distributed Generators (DGs), the antlion algorithm and the Cuckoosearch algorithm
The Genetic Algorithm (GA), Cuckoo search optimization algorithm and the Antlion Optimizer algorithm (ALO) techniques are presented in this paper to solve the problem of selecting the optimal size and location of DG placement in in the radial distribution system IEEE-69 bus system as a radial distribution system in order to minimize the total power losses
Summary
The configuration of an Electrical Distribution System (EDS) is adjusted to diminish the real losses. There are many ways to reduce the active power losses of distribution network. Genetic Algorithm is selected to unravel the network reconfiguration issue as well as the capacitor placement issue These two ways will be merged together to reach the best effect of reducing losses. To check the efficiency and the performance of the mentioned algorithms in choosing the ideal location and size of DGs or Capacitors in radial distribution power system, three test systems were used [4]. Examining the power flow of a certain network in any radial distribution-system is considered to be the life-line of the network It demonstrates the active and reactive power losses in each branch of the networks in addition to the demonstrations of the voltage magnitudes of each bus of the network under the steady state. 0.9 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 Bus or Branch
