Abstract
The significance of Distributed Generators (DGs) in the technical and economic operations of electric power distribution systems cannot be overemphasized in recent times. This is essential as a result of the incessant increase in electrical energy demand, which is becoming considerably difficult to meet with the conventional means of energy supply. Thus, DGs offer better alternatives for providing a quality supply of energy near the site of consumption. This type of energy supply is cleaner and cheaper most of the time due to the lessened transmission losses, which consequently reduced the cost of operation at the transmission and distribution levels of the power system. In this work, an approach for placement and sizing of solar PV DGs into radial distribution networks (RDN) based on the solar PV capacity factor of the site was analyzed using particle swarm optimization. The aim of this study is to analyze the effect of the approach on the real and reactive power losses within the network as well as the bus voltage profile. Constraints on credible system operation parameters, which includes bus voltage limits, power balance, and power flow limits, are considered in the formulation of the optimization problem. In order to verify the viability of the deployed approach, steady-state performance analyses were executed on IEEE 33-bus RDN; and the results obtained were compared with the results from other approaches reported in the literature.

Summary
In the early times, centralized generation was the only means for the provision of electricity, which involves using conventional generators for the production of electricity. In recent times, the modernization of power system structure is highly essential due to the increase in electrical energy demand, and this has necessitated the need to move from centralized generation to decentralized generation. The decentralized generation consists of using small power-generating units either in the form of renewable or non-renewable energy sources installed and integrated into the power system at the distribution end very close to the local users [1]. The distribution network is usually radial in structure in its operational simplicity [2]. In recent years, the distribution networks (DN) have witnessed a rapid integration of distributed generators (DGs) as a result of the advances being made in renewable energy technologies. There has been an increase in government drives to reduce carbon emission, achieve energy sustainability, enhance iations
